How to Stop a Home Gym from Smelling

How to Stop a Home Gym from Smelling

Working out at home can be a great way to save money and get in shape, but it can quickly become a deterrent if your home gym starts to smell bad. In this blog post, I will discuss tips on stopping a home gym from smelling. We will also cover some common causes of gym odor and how to prevent them. Let’s get started.

Why Do Home Gyms Smell Bad?

There are several reasons why home gyms can start to smell bad. They include:

Poor ventilation

Ventilation is among the most critical factors in keeping a home gym smelling fresh. If your gym is located in an enclosed space with little or no ventilation, the sweat and body odor from your workouts will quickly build up, leading to a nasty smell.

Dirty equipment

Another common cause of foul odor in home gyms is dirty equipment. If you don’t regularly clean your gym equipment, it can start to harbor bacteria and dirt, which can lead to an unpleasant smell.

Stale air

If your home gym is located in a basement or other area that doesn’t get much fresh air, the air can start to feel stale and stuffy. This can also contribute to an unpleasant odor.


Another common cause of bad odor in home gyms is moisture. When you sweat during your workout, the moisture can collect on surfaces and start to grow mold or mildew. This can lead to a musty or unpleasant smell.

Bacterial Buildup

This is one of the most common causes of bad odor in home gyms. When you sweat during your workout, the bacteria on your skin can transfer to surfaces in your gym. Over time, this can lead to a buildup of bacteria, which can cause an unpleasant smell.

Using scented body oils

Another unlikely factor causing your home gym to smell is the scented body oils you might be using. These oils can interact with the sweat and bacteria on your skin to create an unpleasant odor.

Rust or rubber odors

Rubber can sometimes give off an unpleasant odor, especially when it’s old or worn. If your gym equipment is made of rubber, the bad smell could be the source. Rust can also cause an unpleasant odor, especially if it’s left to build up on surfaces.

Leaving dirty gym clothes in your gym bag

If you leave your gym clothes in your gym bag after your workout, they can start to harbor bacteria and sweat, which can lead to an unpleasant smell. Be sure to wash your gym clothes as soon as possible after each workout.

How to Stop a Home Gym from Smelling

Now that we’ve covered some common causes of bad odor in home gyms, let’s discuss tips on how to stop a home gym from smelling.

Here are a few tips:

Make sure your gym is well-ventilated If your space is not well-ventilated, the sweat and body odor from your workouts will quickly build up, leading to a bad smell. Be sure to open windows or use a fan to circulate fresh air during and after your workout.

Even after your workout sessions, you want to make sure you are airing out your space. This will help to prevent the smells from becoming trapped and intensifying.

  1. Invest in a quality air purifier

Air purifiers are among the best ways to remove bad odors from your home gym. They work by circulating and filtering the air, which helps to remove bacteria, dirt, and other contaminants that can cause an unpleasant smell.

If you choose an air purifier for your home gym, you must pick one with a HEPA filter. This will help remove any bad smells and pollutants from your gym.

  1. Clean your equipment regularly

Another important tip for preventing bad odor in your home gym is to clean your equipment regularly. This includes wiping down surfaces after each use and deep cleaning them weekly.

Deep cleaning can be done by using a disinfectant or sanitizing surface wipes. You can also use a vinegar solution to deep clean your gym equipment. Just be sure to rinse the surfaces well after cleaning them with vinegar.

  1. Wash your gym clothes regularly

Another important tip for preventing bad odor in your home gym is to wash your gym clothes regularly. Gym clothes can harbor bacteria and sweat, leading to an unpleasant smell. Be sure to wash your gym clothes as soon as possible after each workout.

  1. Use a time-release air freshener

Time-release air fresheners are a great way to keep your home gym smelling fresh and clean. These air fresheners slowly release fragrance over time, which helps to mask any foul odors that might be present.

Be sure to choose an air freshener that is designed for small spaces such as home gyms. You also want to choose a fragrance you enjoy, as you’ll be smelling it for a while.

  1. Use a dehumidifier

Since moisture is among the most significant contributors to bad odor in home gyms, using a dehumidifier can be extremely helpful. Dehumidifiers work by removing moisture from the air, which helps prevent bacteria and mold growth.

Choose a dehumidifier that is big enough for your space and has an automatic shut-off feature. You also want to empty the dehumidifier regularly, as the collected water can become stagnant and lead to a bad odor.

  1. Check for mold and mildew

Mold and mildew can also cause an unpleasant smell in your home gym. These growths thrive in moist and humid environments, so be sure to check for them regularly.

If you do find mold or mildew, be sure to clean it up immediately. You can use a commercial mold and mildew cleaner or make your own by mixing equal parts of water and vinegar.

  1. Wear clean clothes

This may sound like a no-brainer, but it’s essential to make sure you are wearing clean clothes when working out. Sweat and body odor will quickly build up on dirty clothes, creating an unpleasant smell.

  1. Use charcoal filters

Charcoal filters are another great way to remove bad odors from your home gym. These filters work by absorbing odor-causing particles from the air, which helps to keep your gym smelling fresh and clean.

Activated charcoal filters are the most effective type of charcoal filter. However, there are so many out there to choose from that it can be challenging to know which one to get. Do your research and read reviews to find the best charcoal filter for your needs.

  1. Use essential oils

Essential oils can also be used to freshen up your home gym. These oils are known for their ability to mask bad odors and create a pleasant scent in your space.

You can either diffuse essential oils throughout your gym or make your own DIY air freshener using a few drops of oil and water. Be sure to choose an essential oil that you enjoy the smell of, as you’ll be smelling it for a while.

  1. Use clean towels

Make sure the towels you use in your home gym are clean. Towels can harbor bacteria and sweat, which can lead to an unpleasant smell. Be sure to wash your towels regularly and store them in a dry place when not in use.

You may also want to consider using paper towels for wiping down surfaces after each use. This will help to prevent the spread of bacteria and keep your gym smelling fresh.

  1. Avoid carpets

Carpets are a breeding ground for bacteria and can quickly become smelly. If possible, avoid using carpets in your home gym. If you must use a carpet, be sure to clean it regularly and vacuum it often.

Consider using a yoga mat or exercise mat instead of a carpet. These mats are easy to clean and won’t harbor as much bacteria. Plus, they provide a comfortable surface to work out on.

  1. Hire professional cleaners

For all-around deep cleaning and freshness, hire professional cleaners to clean your home gym regularly. They will be able to get rid of any bad odors that might be present and leave your gym smelling fresh and clean.

Be sure to ask about their cleaning methods and products before hiring a company. You want to ensure they use safe and effective products that won’t damage your gym equipment.

Following these tips can keep your home gym smelling fresh and clean.

Final Thoughts

Taking simple precautions is easy to prevent your home gym from smelling bad. Be sure to use a dehumidifier, wear clean clothes, and use charcoal filters to keep your gym smelling fresh and clean. You can also use essential oils or hire professional cleaners for an all-around deep clean.

Hopefully, this article has given you some helpful tips for stopping a home gym from smelling. If you have any other suggestions or questions, share them in the comments below.

Dehumidifier Smells Musty?

Does Your Dehumidifier Smell Musty?

Musty is a word that describes the smell of mold.

When your dehumidifier smells musty, it is almost more than certain that it has mold and bacteria growing in the water or the filter and you need to give the whole unit a thorough disinfecting.

Dehumidifiers like their cousin, the humidifier have a predisposition for becoming moldy because of standing water.

And dehumidifiers even more so.

dehumidifier is moldy


1.  The Dark

The fact that dehumidifiers are collecting water into a basin that is dark makes them more likely to grow mold and bacteria even faster. Low light and dark are essential for mold to grow.

2. Collect airborne contaminants

Dehumidifiers also have the added component of removing airborne germs like bacteria, molds, spores, and pollen from the air which go into the water tank and are allowed to grow and populate till the tank is emptied and cleaned.

3.  Not visible

Unlike a humidifier that usually has a clear basin that you can see the water and get a visual idea of whether it is getting dirty, dehumidifiers collect water into a bucket that you cannot see.

And in this case, out of sight, out of mind, can mean that mold and bacteria can get a stronghold.

With all this in mind you can see that a dehumidifier has an even greater predisposition to growing bacteria and mold inside of the water than a humidifier.

This is a very serious situation when it is not taken care of in a timely manner.

Inhaling bacteria that has grown on water can make you very sick.

Legionnaires disease and Pontiac fever to a lesser degree or diseases that are caused by breathing in water grown bacteria.

Legionnaires disease is responsible for death in many people, especially the elderly and people with weakened immune systems.

Whether you’re talking about a dehumidifier, a humidifier, or an evaporative cooler, these types of appliances are prone to becoming germ farms.

And they all require a stricter attention to keeping them clean because of that fact.


There is one caveat to helping you keep a dehumidifier cleaner longer. That is to run a continuous hose from it so that the water does not collect in the dehumidifier but goes outside.

But regardless, even with the continuous hose, they need to be cleaned often to ensure that they are kept safe and healthy.

how to clean a dehumidifier

How to Clean Your Dehumidifier

Routine cleaning of the dehumidifier is essential for keeping it from developing germs and bacteria and also for running efficiently.

The main components that you want to dial in on when cleaning a dehumidifier are:

  • The water basin
  • The filter
  • The coils
  • outside

1. The water basin

Arguably the most important part of cleaning a dehumidifier is keeping the water basin and around it disinfected.

Bacteria can begin to grow in water in as little as 48 hours. And since dehumidifiers have all the criteria; low light, dust, and moisture, for mold to flourish,
Special attention should be given to the water basin to ensure that it is kept clean and disinfected thoroughly and often.

Fortunately it’s not a tough job.

a. unplug the machine

No use risking the chance of being shocked regardless.

To clean the water basin on your dehumidifier, simply take the basin off and dump the water out.

Using cleaning vinegar, which is a little more acidic than regular white vinegar, completely scrub out the basin and rinse it.

Add a couple of cups of vinegar back into the basin and fill it up. Allow it to sit for at least 30 minutes.

Dump the vinegar out, rinse it out with warm water and allow it to completely dry.

2.  The filter

Dehumidifiers are almost identical to window air conditioners in their mechanics.
And if the filter is allowed to get dirty enough to inhibit the airflow, the machine will not do its job properly.

To clean the filter, simply pull it out and knock off the loose material into the trash.

To take a cleaning brush and scrub the rest of the debris out of the filter.

Knock it off again, into the trash.

At this point, if the air filter is particularly dirty, canned air can be used to blow the filter out even further.

And if it’s still grimy after that, wash it under the faucet using warm water.

If you end up having to clean the filter with water, be careful to let it dry completely before you reinsert it.

Since water is one of the components of mold taking root.

3. The coils

The coils are less likely to be dirty and are not considered an essential part of routine maintenance. But they can still get dirty over time.

If the coils on your dehumidifier or window AC get dirty. The machine will not run as efficiently and use more energy.

Dirty coils can also cause the machine to freeze up quicker.

To clean the coils, a can of coil cleaner can make the job very easy.

Coil cleaner foams up similar to bathroom cleaner. Simply spray the coil cleaner all over the coils, let it foam up and sit.

After it has sat for the amount of time that the direction says, wash the coils off with warm water, preferably with the spray bottle, and let it completely dry.

4. Outside

Wipe the outside thoroughly with cleaning vinegar. Sure to get into the nooks and crannies where water can get access to and eventually cause bacteria to grow on the outside of the machine.


Does the dehumidifier smell musty?

A musty smell is almost always certainly an indication that there is mold somewhere in the vicinity.

When you smell that mustiness coming from your dehumidifier, then the most logical reason is that it has mold and bacteria growing or starting to grow in the water or even around the water basin.

Since dehumidifiers pull moisture out of the air that is filled with bacteria and allergens like mold spores and dust mites,

The moisture that is collected inside of the dehumidifier has a chance of developing mold and bacteria even faster than just standing water on its own.

And you couple that with the fact that it is dark inside of the basin, you have all the ingredients for mold and bacteria to take root faster.

Bacteria growing on standing water can be dangerous to breathe.

Legionnaires disease is caused by inhaling a certain bacteria that has grown on water.

So keeping the water basin emptied and thoroughly cleaned on a dehumidifier is very important.

Fortunately it’s a job that you can do with some household items like a scrub brush and some vinegar.

   And if the area where you have your dehumidifier can accommodate it, you can skip the water basin all together and hook up a continuous hose. So that the water coming into the machine goes outside instead of collecting into a bucket.


How to Reduce the Humidity in a Air Cooler?

Can you reduce humidity in an air cooler?

Evaporative air coolers have the advantage of being cheaper to run than a portable or window air conditioner because they don’t use as much energy.

Air coolers are a much simpler design in that they are basically a fan blowing over and through water.

  And if you live in a very dry area, the extra moisture that evaporative air coolers create is welcomed. And evaporative air coolers do a very nice job of cooling a house when the air is dry.

But if you live in an area with a normal range of humidity, air coolers have the disadvantage of creating much more humidity in your house then you need.

And the result is the uncomfortable feeling of stickiness, as well his other symptoms like fatigue. Too much humidity can just put you in a bad mood. 

So it’s not surprising that one of the first things people want to know about air coolers is how to reduce the humidity in the house when using one.

Unfortunately there is not one magic bullet to reduce the humidity created by an air cooler.

But… There are a few things that can help you reduce the humidity in your home caused by an air cooler.

high humidity remedies1.  Open Windows

There is a misconception that air coolers work best when a room is tightly closed. Not so.

Opening the window or Windows on the other side of the house actually helps pull the air through the house making the air cooler more efficient.

And the open windows let dryer air back into the house which can help lower the humidity caused by the air cooler.

2.  Extra Fans

Adding some extra fans in the house will help dry the air.

Anything that causes rapid air movement, including a fan, can evaporate moisture.

Though the amount of air being moved by a fan may not amount to much drop in the humidity, having air blowing directly on you will help reduce the feeling of humidity.

Think about it this way: if you were to sit in front of a fan with your hair wet, your hair would dry faster.

If your skin is feeling sticky from humidity and you sit in front of a fan, the humidity on your skin would dry out.

3.  Exhaust Fans

What do you do when after you take a steamy shower and the mirror and the windows are fogged over with condensation?

You turn on the exhaust fan.

Same thing in the kitchen. If the air is getting steamy from cooking and boiling, you flip on the exhaust.

Installing and running a few exhaust fans is an excellent ideal to pull some of the excess humidity caused by your air cooler out of the house.

4. Desiccant Dehumidifier

Desiccant Dehumidifiers or dehumidifiers that do not use a compressor and coil system. Instead they use a silica gel chemical absorbent to absorb moisture out of the air.

Silica gel is known as the little packets that are included in all types of products. Anything from shoes to electronics to help keep moisture out.

Desiccant dehumidifiers are full size units that are able to work spaces up to 480 ft.

And they also come in portable containers that you can place around your house.

  To stop a dehumidifier is completely silent because they do not use a compressor or a fan to reduce the humidity.

What about Compressor Dehumidifiers?

Can you a run a dehumidifier with an air cooler?

Technically you can use a standard compressor based dehumidifier to help reduce the humidity caused by an air cooler.

But you have to remember they do exhaust heat out of the rear. Which will compete with the cool air coming from the air cooler. And they are loud.

This is a more experimental approach to lowering the humidity caused by an evaporative air cooler. And it’s probably worth a shot if you happen to have a dehumidifier on hand.

But if you were thinking about purchasing a dehumidifier to lower the humidity caused by a evaporative air conditioner, then it begs the question:
Why don’t you just purchase a window air conditioner or portable air conditioner instead of an air cooler?

Other Natural Humidity Remedies

All natural dehumidifiers are a good way to reduce humidity in your house while running an evaporative air cooler.

Some of the most popular are:

  1. Charcoal briquettes
  2. Calcium chloride
  3. Rock salt
  4. Coffee creamer

1.Charcoal Briquettes



Charcoal is a naturally porous absorber that can be used as a do-it-yourself dehumidifier.

Simply filling some containers with about 8 to 10 charcoal briquettes and setting them throughout the house will have a dehumidifying effect that will help dry out your air.

2.Rock salt

Rock salt is also a well-known damp absorber.

The idea is to take two buckets. Drill holes in the bottom of one and put it inside of the other bucket was something in between the buckets to keep them apart. ( It doesn’t matter what you use, I use the lid off of a peanut butter jar that was in the trash)
Then fill the top bucket with rock salt.

3.Calcium Chloride

Calcium chloride is an all natural dehumidifier also.

The ideal here is to take a sock and fill it with calcium chloride then hang the sock somewhere with a bowl or a bucket beneath it to capture the condensation that will begin to drip from it.

4.Coffee Creamer

Cheap coffee creamer is a surprisingly good moisture absorber. And there is really no technique to using it.

Simply purchase the biggest container of cheap white coffee creamer that you can buy and pour it into a bowl.

The coffee creamer will draw moisture.

You’ll know to replace it when the coffee creamer gets too hard.

Dehumidifying Plants



Plants are natural dehumidifiers all on their own.

Anything that pulls moisture out of the air is going to be a dehumidifier and plants certainly qualify. Some plants more than others.

The best plants for dehumidification or plants that have waxy or hairy leaves with a large surface area.

Here’s just a few as an example.

1.  Cactus

Cactus flourish in dry regions because of their ability to draw moisture out of the air.
There’s not an easier plant to take care of than a cactus either.

2.  English ivy

English IVY is a super easy plan to take care of that’s also a great starter plant. It also is a great dehumidifier and thrives off of the humidity in the bathroom.

3.  Spider Plant

Spider plant is an easy indoor favorite. It grows easy and it grows quick in about any circumstance you put it in.

4.  Peace lily

Peace lily is a lovely plant that is not only a dehumidifier, is a air purifier too. This plant removes air pollutants like formaldehyde and xylene and is a addition to your home if you suffer from seasonal allergies or asthma.


Does air cooler increase humidity?

No doubt an air cooler increases the humidity in the space it is being used in.

Evaporative air coolers or basically a fan blowing over evaporated water as a means of cooling the air off as it’s blowing.

Essentially a giant humidifier.

Can an air cooler cool the room?

An evaporative air cooler can cool the room off nicely in the right circumstances. For instance, if you live in a dry area, then an air cooler can make a room feel very comfortable.

But if you live in an area that is already humid, then an air cooler will just pile on the humidity and add insult to injury.

Is there an air cooler with humidity control?


Unfortunately there’s not really an air cooler that has humidity control since the primary function of an air cooler uses humidity to help cool off a room.

But there are a few ways to help reduce the humidity caused by air coolers that are worth looking into.

Opening the windows on the opposite of the house will create air flow and help dry out the air at the same time.

Exhaust fans will also help pull the moisture out of the air.

Desiccant dehumidifiers or dehumidifiers that absorb moisture out of the air without the noise and the heat of a compressor.

They can be purchased as full size dehumidifiers or as containers of desiccants that you sit around the house.

There are also some nice do-it-yourself dehumidifiers that can do a good job.

Rock salt and calcium chloride make great moisture condensers.

Charcoal briquettes and cheap coffee creamer are also great humidity absorbers.

And don’t forget about the house plants.

House plants are one of nature’s Best dehumidifiers and they add oxygen to your air. Some plants even purify the air as they dehumidify.

Should You Run a Dehumidifier and a Air Conditioner at the Same Time?

If you’re a homeowner, you are well aware of the difference a rainy spring in the summer season can make compared to a dry spring and summer.

  And there are a lot of advantages that come with the extra rain. For one you don’t have to spend an arm and a leg watering the grass.

Plus the vehicles get a lot of good washing without going through the car wash or pulling out the hoses and brushes at home too.

But there are definitely disadvantages to having an extra rainy season.

And one of the primary ones is the amount of humidity in the home and how to deal with it.

Dehumidifiers are machines that are designed with excessively humid seasons in mind. But they come with a lot of questions.

Should you run a dehumidifier and air conditioner at the same time?

You shouldn’t have to run a dehumidifier at the same time as an air conditioner in an average rainy season.

The air conditioner dehumidifies as it cools and as long as you’re talking about typical on and off rain, the air conditioner should keep up just fine.

But as you know, there are always exceptions to the rules.

And sometimes a rainy season means that the rain does not let up for days and sometimes for weeks.

  And if you’re in Seattle or Florida, the climate may be excessively humid, just because.

The rain and humidity in Northern Texas last year was so high that it looked like the air conditioners were busted and had major leaks going on because of the amount of condensation that was pouring out of them.

The window air conditioners were creating so much condensation that the ground beneath them was basically just saturated mud.

So yes there are times when the humidity can be so high that the air conditioner is going to have a hard time keeping up.

In that case, you can place a dehumidifier or two in your house to help reduce the indoor humidity and take some strain off of the HVAC. (Central heat and air)

And you could possibly be avoiding an expensive service call for your HVAC down the line by helping it out now with a dehumidifier.

where do you put the dehumidifierBut where do you put the dehumidifier?

Good question.

Dehumidifiers expel heat from the rear. So placing them in a room that you are using is not the ideal situation.

But as a means of reducing humidity to take the strain off of the air conditioner running continuously, you don’t necessarily have to have the dehumidifier in the same room that you live in.

Placing the dehumidifier or dehumidifiers in bedrooms or guest rooms that are not being used can still reduce the humidity enough to help the AC.

If you do not have extra rooms, place a dehumidifier, you can minimize the heat by making sure that the filter and the coils are kept clean.

And you do not have to have the heat coming off of the dehumidifier pointed at you.

Just make sure that the unit is not against the wall or draperies, etc.

Can you use a window air conditioner as a dehumidifier?

Most modern window air conditioners have a dehumidifier setting that allows you to run the unit as a dehumidifier (dry mode) without any cold air blowing.

The effectiveness of a window air conditioner to reduce humidity won’t be on the same par as a dehumidifier because the heat that a window air conditioner creates is expelled outside.

  And the heat from a dehumidifier is expelled inside and used to create a circle of humidity to extract the humidity out of a room further.

But a window air conditioner does not have to be in dry mode (dehumidifier mode) to dehumidify.

And as a means of reducing the strain on the main air conditioning, you can run the window air conditioner as a supplemental air conditioner.

That way it will be helping with the cooling and the dehumidifying.

Plus there are many times where certain spots in the house are not as well cooled by the HVAC as others because of the amount of vents or distance of the vents from the main air conditioning plenum.

So putting a window air conditioner in or near those areas can actually be a good solution to expanding your central heat and air during the summer.

More and more, you are starting to see window air conditioners that have a heat setting on them too. So provided you have the right window air conditioning, it could be a solution for the low heat in those areas during the winter too.

  But remember, the more air conditioners or dehumidifiers you have running, the more amount of energy it’s going to take. And dehumidifiers and window air conditioners are both considered energy hogs.

But neither are considered as much of an energy hog as the main HVAC. And when it is running overtime to keep up with the amount of humidity,

Finally. What if you’re using evaporative air cooling?

Can you run a dehumidifier at the same time as an evaporative cooler?

Evaporative cooling basically amounts to a fan blowing over water to cool off the air as it enters into your room.

In dry areas, they work very well.

In humid areas, not so much.

And one of the main questions that people have about air coolers is how they can reduce the humidity in the house that comes along with using an air cooler.

A dehumidifier will help reduce the humidity caused by running an air cooler.

The purpose of a dehumidifier is to extract humidity from a room. Rooms that are being cooled with evaporative cooling are humid.

But you have to remember that dehumidifiers do expel heat and that the cool air that you get from a water evaporator is not on the same par as running a refrigerated air conditioning system.

  So you may find that the heat from the dehumidifier might conflict with the cool air from the air cooler more so.

And the amount of humidity might outpace the dehumidifier.

  Evaporative air conditioning even with a dehumidifier is not really going to be ideal if you’re having an excessively humid season.

Can you use a window air conditioner as a dehumidifierRecap

Can you run a dehumidifier at the same time as an air conditioner?

There are times when running a dehumidifier with an air conditioner can actually help take the strain off of the main air conditioning and cool down the house better.

If you’re having an excessively humid season, the air conditioning can run 24/7 trying to keep up with reducing the humidity.

Dehumidifiers can offset the amount of work the air conditioner is having to do.

Window air conditioners used as  dehumidifiers

Window air conditioners typically have a dehumidifier setting called dry mode that allows you to run the unit as a dehumidifier only.

But window air conditioners can also supplement the main air conditioning because they dehumidify and add cold air to the room at the same time.

This can be a good solution especially if you have hot spots around the house where the main air conditioning is not doing the full job.

  And window air conditioners can be purchased with a heat setting to offset the cool air from those same spots that are not getting adequate air from the HVAC.

For people using evaporative cooling, dehumidifiers can offset the amount of humidity being introduced into the room by the air cooler.

But air coolers are not necessarily made for regions that can experience high humidity.

And you may find that running dehumidifiers may reduce the humidity in the air enough to make the room comfortable without having to run the air cooler at all.

And since window air conditioners and dehumidifiers, depending on which one you purchase, can be a comparable price, you might decide that the better money is spent on a window air conditioner.


Can You Run a Dehumidifier with the Window Open?

Should you run a dehumidifier with a window open?


A dehumidifier requires that a room be sealed off, at least windows and doors closed to function optimally. Letting outside air in while the dehumidifier is running dilutes the process and introduces new moisture that increases the amount of energy it takes and decreases the effectiveness.

Opening the window in lieu of running the dehumidifier is an option if the humidity inside the room is higher than the humidity outside.

For instance, you’ve recently taken a steamy shower and you want to air out the room. Opening the window or turning on the extraction fan is a better option than running a dehumidifier.

Other similar indoor humidity problems can be related to running an evaporative air cooler or simply washing clothes and dishes.

These are usually temporary humidity problems that can be alleviated by letting some fresh air in.

But typically the indoor humidity is relative to the outdoor humidity. A rainy season outside will cause the indoor humidity to rise as well.

Hot humid temperatures outside will gravitate inside.

“Opening a window while you’re using the dehumidifier when the outdoor humidity is as high or more than the indoor humidity, you have zero chance of decreasing the humidity indoors with a dehumidifier.”

Indoor humidity problemsIn fact you will get a better result out of your dehumidifier if you take steps to seal up the windows and doors even further while you’re using a dehumidifier.

Most indoor humidity problems are related to the outdoor humidity affecting the indoor humidity levels.

Basements for instance, are usually built directly next to dirt that has a heavy moisture content. That is why the basement usually seems damp compared to other rooms.

Concrete walls can develop cracks where moisture can seep in from the ground and depending on your style a basement, pipes can be exposed and introducing moisture if there is any leakage.

Other areas like crawl spaces beneath the house can be continuously moist which has a direct effect on the moisture level inside of the house because of moisture coming up beneath the floor.

  A typical problem with crawl spaces is water in the yard that has etched out a ravine running to underneath your house. Broken gutters or dirty stopped up gutters can also be a cause of water seeping under the house instead of being directed out from the house.

Crawl space encapsulation is a process that uses a barrier to keep moisture from the ground from keeping moisture that is in the ground from humidifying your house through the floor.

Crawl space encapsulation can also include putting a large industrial dehumidifier beneath the house to extract the moisture.

But if the indoor humidity is much higher than the outdoor humidity, then you need to locate the source of the moisture and take steps to stop it.

Anywhere you have a leak, you have extra moisture in your home. A broken pipe, gaps in your windows or doors, or a leaky ceiling can all be a continuous source of humidity inside the home that if not fixed will cause the humidity to be high indoors.

  And running a dehumidifier even though it may be necessary to maintain a good comfort level in the meantime is only an expensive Band-Aid till you get the problem fixed.

Indoor humidity problems.


Humidity can do a number on the indoor structure of your house.

Window sills can warp and rot, wood flooring can expand as well as warp as well become creaky.

Ceiling texture can start cracking and flaking off and wallpaper can start coming loose.

And though very important, more important is the fact that your air quality can be compromised and cause allergies, headaches, fatigue, and even other more serious symptoms if mold has been allowed to take root and become part of your ambient air makeup.

How do you know?

How do you measure the humidity in your home?

Of course humidity is a relative term that means one thing to a person living in Arizona and quite another thing for a person living in Florida.

Certain climates especially if they are near the ocean are going to naturally have a higher level of humidity in the air.
And your personal comfortability meter is going to be a lot higher.

But if you are used to living in a dry climate and you take a vacation to the ocean, you may be completely overwhelmed by the humidity level.

So comfortability is not necessarily the best measuring stick for what is acceptable indoor humidity.

To be more exact and to keep an indoor relative humidity that is not only healthier but better for your home, you have to have a way to measure it.

The hygrometer is a gauge that usually comes in the form of a digital thermo hygrometer that you can install on a wall to be able to keep up with your indoor relative humidity level.

These little tools are inexpensive and can be placed in multiple locations throughout your house as a way to gauge where the higher humidity is coming from.

How do you measure the humidity in your homeWhat should the humidity level be inside your house?


The national library of medicine says that most health issues related to humidity can be curbed by keeping the indoor relative humidity between 40 and 60%.

The homeowners association says that the humidity should be between 30 and 60%.

So the ideal humidity to try to achieve inside the home is about 50%.

Dehumidifiers typically come with a built-in hygrometer and humidistat to gauge the indoor humidity so that the machine will run until the set humidity is reached.

Humidifiers can be purchased with built-in hygrometers and humidistats as well when the indoor humidity has dipped below 30 to 40%.


Can you use a dehumidifier with the window open?

To increase the effectiveness of a dehumidifier, close any windows and doors to the room that you are trying to reduce the moisture in.

Since the outdoor humidity is generally one of the main causes for excessive humidity indoors, opening a window with the dehumidifier running will only cause a never-ending cycle of extracting humidity from the air. And cause the energy hog dehumidifier to be even more expensive to run.

  If on the other hand, the fresh air outside is dryer than the air inside, then opening the windows in lieu of running the dehumidifier could be the better option.

Extraction fans in the bathroom and kitchen as well as the washroom will reduce the humidity without running a dehumidifier as a necessity also.

If the indoor relative humidity is consistently higher than the outdoor humidity, then you are more certainly looking at an indoor problem such as a leak from a pipe.

Fixing the issue is the only solution at that point.

If the outdoor humidity is continuously high then reducing the exposure indoors by sealing the house and fixing any issues with moisture and water humidifying from beneath the house is the key.

Maintaining an indoor relative humidity between 40 and 60% is the main objective.
You can use a hygrometer and even place them throughout your house to measure your humidity and gauge where the higher humidity levels are sitting in your home.

Can I Use a Humidifier Without a Air Conditioner? – With?

Can I use a humidifier without air conditioning?

The humidifier does not need cool air from an air conditioner to function. Its moistens  the air regardless of the temperature.

The humidifier is a device that’s purpose is to add moisture into the air.

And though an air conditioner’s primary purpose is to cool a room, it also dehumidifies in the process.

Air conditioners and dehumidifiers pull warm air out of the room and drag it across refrigerated coils that cause the moisture to condense and exit as a liquid.

This is why window air conditioners have a drip hole in the bottom of the case.

  It is so that the humidity that is pulled out of the air while the air conditioner is running has a place to escape from.

  Humidifiers are more commonly run in conjunction with heating systems and heaters.

During winter months when the air is naturally dryer and the heater is on and off drying the air out even further, humidifiers are used to combat the dry air.

Without the humidifier running you might start seeing a lot of telltale signs like everyone walking around zapping each other because of static electricity. Plus Dry lips and dry and bloody noses, and a lot of congestion.

But that does not mean that there is no need for a humidifier in the summer. Though we primarily think of the summer months as being extra humid, that is not always the case.

In Texas for instance, we have gone months without any rain and temperatures in the ’80s daily.

Which amounts to dry, dusty and windy heat.

You can bet we use our humidifiers with the air conditioner running.

  But, on the other side of the coin, if we’re having a rainy and humid season, you definitely don’t want to do something to add more moisture to the air like run a humidifier.

In fact, a dehumidifier may have to be run in conjunction with an AC when the relative humidity is so high that the AC cannot keep up with dehumidifying.

So regardless of the temperature or of the season, the humidifier is meant to add moisture to the air when the relative humidity is below the 40 to 60% mark.

And while it’s more common in the winter, dry conditions can occur throughout the year.

Getting to know the lingo

Of course there are so many devices, appliances and systems that do something to regulate the air, it is hard to know which is which and what does what sometimes.

  For instance, a true story. For years I personally ran an air purifier retail store.
The only thing we sold was air purifiers. 
We didn’t sell any other types of appliances or or anything that had to do with air other than clean it.

But like clockwork, every holiday when the family gets together, my brother-in-law asked me how my “water filter” business is doing. Jeez.

  The point is, unless you deal with these things on a consistent basis, there is really no need to keep up with what is what.

So when somebody asked me a question like ” can I use my humidifier without the air conditioner?” I’m more likely to believe that they meant “dehumidifier” instead of air conditioner.

The reason I say that is, air conditioners typically come with a dehumidifier setting. So that you can use the dehumidifier without using the air conditioner.

There are many times when the temperature is not all that excessive but the humidity level in the house makes it feel like it’s 110°.

  At those times, you can run the dehumidifier on your air conditioner without running the “cool” setting and be able to cool the house off by extracting the moisture out of the air and never turning the air conditioner setting on at all. 

In that case, the answer is yes. You can run the dehumidifier setting on your air conditioner without running the air conditioner per se.

humidifier-air conditionerRecap.

When someone ask” can I use a humidifier without the air conditioner ?” They can mean one of two things.


They want to know if it’s good to run a humidifier when the air conditioner is on?

Or they are confusing the dehumidifier setting on the air conditioner for a humidifier.

The answer is, you can run a humidifier anytime that the relative humidity is below 30 or 40%, and get benefit out of it.

Even in the summer, there are times when the air is so dry that it calls for a humidifier to be going even with the air conditioner running.

But air conditioners do not come with a humidifier setting.

They do on the other hand come with a dehumidifier setting.

Which leads me to believe that a lot of people confuse the lingo and call the dehumidifier a humidifier.

The dehumidifier on an air conditioner can be run without the air conditioner running on the cool setting along with it.

There are many times when reducing the humidity in a room will increase the comfort because it’s the humidity that’s making the room feel so uncomfortable.

Air conditioners and dehumidifiers are very similar appliances. If you take them apart, their mechanics look almost identical.

The difference is, an air conditioner cools the air as it pulls the moisture out and dispels the heat outside of the room.

A dehumidifier does not cool the room off as it pulls the moisture and it dispels The heat inside of the room which helps pull even more humidity out of the air.

You generally don’t need to run a dehumidifier if you have an air conditioner.

But there are times when the humidity level can be so high that the air conditioner can’t keep up with pulling the moisture out alone.

At that point a separate humidifier can help to reduce the moisture in a house further, cool things off a bit more, and take some strain off of the air conditioner.

Humidifier-Dehumidifier Combo-What Are Some Of The Options?

Unless this is the first thing you’ve read about the subject,

You probably have already realized that a humidifier dehumidifier combo is not really a thing that you can easily find on the internet.

Yes, you might find an experimental one somewhere…

But then again there’s probably a reason why they don’t exactly fill the shelves.

A humidifier and a dehumidifier, though they may sound like the same thing or very similar;

Are actually two very different machines with two entirely different functions.

A humidifier is used to add moisture to the air while a dehumidifier is used to extract moisture from the air.

Humidifiers and dehumidifiers are not two appliances that are ran at the same time.
That’s probably the biggest reason why you don’t find too many combination humidifier and dehumidifier machines available.

dehumidifier-humidifier Though you might be able to make the case that these two devices could be combined and work well together.

Why not? they both have a basin for water.

And you could easily see that basin being  used to capture water when the humidity is too high.
  And when the humidity is too low, adding water to the basin to humidify a room….

But the truth is, a dehumidifier is a pretty hefty device on its own that has a full compressor to condense the humidity out of the air.

   And even the smaller dehumidifiers are quite a bit larger than a room humidifier.

And considering the usefulness you get out of a dehumidifier compared to a humidifier,

  it doesn’t make it all that appealing to have a humidifier that is the size of a dehumidifier.

Another issue that I see is that a region that has a climate with excessive humidity is not likely to have a excessively dry season or vice versa.

And Dehumidifiers are more likely to be used less than a humidifier over the span of a year.

So having a device that is likely to be much bigger out of necessity,
during the time of year you don’t need it, doesn’t make combining a humidifier and a dehumidifier all that appealing either.

The bottom line is that these two devices are just not that useful when combined together. And the expense of doing so would not be worth it.

Dehumidifier Humidifier Combo alternatives

For a lot of people who live in climates that are primary dry, a full blown dehumidifier with pump and hose is just too much.

Desiccants placed around the house can be a good solution and a reasonable combination to go with your humidifier. And they are a fraction of the cost of a full size portable dehumidifier.

The easiest way to describe a desiccant is to remind you of the tiny bags that manufacturers include in packaging to help keep their products fresh.

Those are desiccant bags. And you can find them in everything from cookies to shoes.

  But desiccants also come in much bigger sizes and can reduce the humidity in a pretty good sized space.

Here’s a few examples of desiccant dehumidifiers that you can purchase.


Damprid is a desiccant container that is available in different sizes. It can also be bought in bags with a hanger similar to what you hang a shirt on.

One kind of Damprid includes activated charcoal that is excellent at getting rid of musty smells.
Damprid is an excellent solution to absorb excess moisture in a small area. It can also be put away from view very quickly.

Eva-dry E-500 Mini Dehumidifier



Eva Dry Dehumidifiers run totally silent, have a 10-year life span, and do not require any refills.
These are dehumidifiers with small desiccant absorber beads which are specifically designed for smaller areas such as safes and closets. You may need more than one.
These units can take in up to 8oz of moisture, without the maintenance and emptying irritations associated with the compressor-based dehumidifiers.

Dehumidifiers do not have to be the size of a portable air conditioner either. There are several models that can be used in much smaller spaces.

Levoair Dehumidifier

A small dehumidifier, with the drain hose.
The tiny dehumidifier is able to reduce humidity up to 333 square feet.
It’s very quiet because it doesn’t have a compressor. Which is the reason that most dehumidifiers sound so loud.
It has a handle that it can be carried around with,  and it is water-proof. Easily transportable with fewer chances of spilling.
A drain hose, already built-in, allows you to operate it without having to purchase it separately.

Room ventilation

So far we’ve only talked about combining a humidifier and a dehumidifier in a small portable package.

Many people find themselves with extra dry air in the winter and overly humid air in the summer.

So as we start to go down the rabbit hole of what to do to solve the problem, many times it seems obvious that we need a dehumidifier for the humidity and a humidifier for the dry weather.

But that is not necessarily the the answer.

  With modern building practices, houses and homes are usually sealed up exceptionally well.

  Though that is something you want, it can also be a problem when you’re talking about keeping the indoor humidity at the optimal level.

Sometimes just opening the window and letting some fresh air in will help with a dry or humid room.

But what about when opening a window is not an option? Like in the Winter.

That’s where adding a fresh air ventilation system to your existing HVAC can provide the fresh air into your home that can reduce humidity.

Many of these fresh air ventilation  systems come with humidity sensors so that they do not allow excessive outdoor humidity into the home.

And they also come with built-in dehumidifiers to help reduce the humidity if it becomes a problem also.

Panasonic WhisperComfort Spot Energy Recovery Ventilator

Panasonic WhisperComfort Spot Energy Recovery Ventilator (ERV) is a unique way to offer an even airflow with an integrated ceiling ERV.

It is ideal for one room. The Panasonic FV-04VE1 WhisperComfort Spot ERV Ceiling Insert Ventilator has the lowest rate for continuous air exchange. This ventilator provides fresh air to replenish exhausted air, balancing the air pressure in the home.

Extractor fans

Extractor fans are very useful for bathrooms because they pull the moisture out of the room via a fan  that expels into the attic.

Removing unwanted humidity by extracting it with a fan can be a much better solution than collecting it with a dehumidifier.

Extractor fans are also a great way to reduce humidity in a damp basement that doesn’t really need or have a place to put a full sized window AC.

AC Infinity AIRTITAN T8 Basement Ventilator Fan

  • A fan system that is designed to provide airflow and humidity control to basements and crawl spaces.  
  •  Reduces humidity by generating exhaust airflow, which helps to eliminate foul scents and fresh air out of your home.

Air conditioning

Refrigerated air conditioning, whether it be what’s coming into your home via the central heat and air or a window air conditioner automatically combine dehumidification as part of cooling your home.

Summertime heat can be compounded by high humidity in the air.

And it’s at those times that cooling down with a fan or even a evaporative cooler are not going to suffice.

Newer AC units most always come with a dehumidifier setting besides their natural humidifying capacity.



  • The LED display on the front of its panel
  • Provides fast and efficient cooling in rooms that range from 500 square. Ft.
  • Dehumidification can help maintain a comfortable atmosphere within

Refrigerant with flammable properties that could cause a fire or even an explosion


Doing a search for a dehumidifier and humidifier combo is mostly likely a dead end.

Even though they may sound like a great combination of products to pair together,

They are not two products that are ever used at the same time and the technologies that they use to do their thing are completely different.

They are not compatible in the same way that say, combing a dehumidifier with an air purifier would be. Since they both work to reduce airborne pollutants.

Some solutions that can help manage humidity in the home and be a good combo with a humidifier or dehumidifier are products like:

  • Desiccants
  • Fresh Air Ventilation systems
  • Extractor fans
  • Air conditioners

You can purchase a humidifier with all the bells and whistles you can think of. But none of them will dehumidify.

Same thing goes for dehumidifier. There are some amazing units out there that will dry your room out like a prune. But they won’t add a bit of humidity.

Wall Mounted Dehumidifier (What are Some of the Options?)

Excessive moisture in your home can cause mold to take root and dust mites to thrive in abundance.

The result can be damage to the wood and drywall as well as the insulation inside the walls.

Allergies also have a tendency to flare up when the humidity is high inside of the house too. Mold spore and dust mite allergies are two of the most common household allergens that have their origin in high humid air.

Fortunately, it’s a problem that can be solved with the use of a dehumidifier.

Dehumidifiers can reduce the moisture in the air at a surprising rate and amount.

They not only help save your hairdo but can save you a lot of money in energy cost by taking the weight off of the home air conditioning system.

Which will also lead to less maintenance on your HVAC unit.

But said dehumidifiers are not always the most sexy of appliances. In fact, they can be a big eye sore that takes a lot of space, especially when they have a hose and pump hooked into them.

This is one of the reasons that homeowners are searching for a way to reduce the humidity in their home or also looking for a way to keep the dehumidifier out of the way and out of the middle of the floor.

Another reason is that dehumidifiers more than not, come with a drainage hose option. That means that they depend on gravity for the water to drain freely.

Mounting the dehumidifier to the wall is a way to ensure that there is enough height for the water to drain properly.

wall mount dehumidifier Wall Mounted Dehumidifier – What are some of the options?

Depending on the area and how much humidity you need to consistently reduce,

The solution may be as simple as keeping a few small desiccant dehumidifiers around the bathroom and in closets.

Desiccant dehumidifiers use silica gel to absorb humidity. Silica gel is more popularly known as the little packets that come in different types of products like running shoe boxes or potpourri, etc.

When used as a full-size dehumidifier, the amount of silica gel is not only much larger, the units must be charged in order to absorb enough humidity to be useful.

But humidity problems that require a larger robust solution like in the basement, you may look at a full in- wall dehumidifier or whole house dehumidifier that is required to sit on a mounted shelf or suspended stage.

Here’s a little more of a breakdown and some suggested methods that could be employed.

The dehumidifier industry is packed with manufacturers that build huge dehumidifiers that can reduce a mountain of humidity.

But sometimes, you just don’t need that much power or humidity reduction.

Many times the problem is as simple as a bathroom that doesn’t have an exhaust fan or a big enough exhaust fan.


Wall Mounted Dehumidifier for Bathroom


The bathroom it’s typically the smallest room in the house and putting another appliance on the floor is out of the question and even having a big appliance like a dehumidifier mounted to the wall in the bathroom is going to take up an enormous amount of space.

  But there is an alternative, and it just happens to be wall mounted.

Small Desiccant dehumidifiers like the Eva dry can absorb 4 to 8 oz. of water before recharging.

And the price for one is under $20.

Desiccant wall mount dehumidifiers are ideal for bathrooms, closets, cars, and gun safes.

And you could buy 15 of them for the price of one mid-size dehumidifier.

If your humidity issues are pretty much delegated to the areas in your house where there’s a lot of steam, aka the bathroom, laundry room, and kitchen.

Desiccant wall mount dehumidifiers can do a great job without ever having be emptied or have any type of hose attached to drain from. A huge plus.M

1. Eva-dry E-500 Renewable Mini Dehumidifier

It is rechargeable and excellent for your closet areas, cabinets, and gun safe.


DampRid is a silica gel all-in-one bagged absorber. It is ideal for hanging in the closet, cabinets, or anywhere in the home where you are experiencing mustiness and damp air DampRid also has a version that comes with Activated Charcoal 

The average size basement is around eight hundred to a thousand square feet.

Which in dehumidifier terms means a whole different level of cost to purchase a wall mount dehumidifier.


Below is a few Ideas and Products for mounting a dehumidifier on the wall.

Storage utility hooks

A easy solution for mounting a dehumidifier on a wall if you are willing to think outside of the box and you’re not specifically looking to mount a dehumidifier for the aesthetic appeal,

Then coupling a dehumidifier that is outfitted with a carrying handle with storage utility hooks is a viable option.

Storage hooks can hold anywhere from 30 lb to 80 lb depending on the material that you put them into.

Since basements usually have cement walls, they are ideal for holding heavy objects.


Donatello dehumidifier with drain hose

This small dehumidifier covers 350 square feet and holds 68 Oz which equates to 34 lb. Which is easily in the range of weight that standard utility hooks can handle.

This dehumidifier runs without a compressor which means that it is very quiet and can run all day and all night without making any loud noises.

It does not however come with a hygrometer.
To be able to monitor your relative humidity in order not to run your dehumidifier too long or not long enough you will need to purchase a separate hygrometer.

Though it is a smaller dehumidifier, you can see how a dehumidifier could be mounted to the wall but simply sitting the unit on storage hooks using the handle.

A shelf that can handle 40 to 50 lbs. is the same concept. Sitting your dehumidifier on a shelf will get it off the ground and give it the gravity it needs to drain without a pump.


Santa Fe Ultra MD32 in-wall dehumidifier

Santa Fe In-Wall Dehumidifier (UltraMD33)The Santa Fe Ultra MD32 in-wall dehumidifier fits inside your wall between two studs.

It can handle a 1200 square-foot basement very well and it has a lot of perks like almost silent operation since it is inside of the wall.

It will also collect up to 33 pints a day for multi-family housing.

It has an awesome finished look for a dehumidifier.

Some of the features include a

  • Moisture sensor

This is a sensor that alerts you when there’s any type of leakage.

  • 4 year warranty due to its galvanized steel cabinet that is built to last.
  • Can work in a variety of temperatures. Including 49° which is cooler than most dehumidifiers.
  • Very quiet. At 46db it is approximately the volume of a refrigerator.

The downside is that it does not come with a pump and the installation kit for it is also purchased separately.

The drain hose will also have to be installed inside of the wall.

If your basement is not finished, it does have an installation kit for you too mounted on the outside of the wall.

This dehumidifier will keep you from having a messy portable dehumidifier with a pump and garden hose running out of it sitting in your basement.

2. EBac AD850E

Ebac AD850E DehumidifierThis dehumidifier is wall mounted and can also be freestanding. It has the look of a hotel air conditioner.

It can easily handle a large basement up to 1700 square feet.

This commercial wall mount dehumidifier looks great. The noise is kept below 50 db and it can operate in a room as cool as 41 degrees.

But it does not come with a hose..

This dehumidifier also doubles as an air purifier and comes with two removable washable air filters.

It’s contemporary design lends itself for you in a variety of commercial settings including pools, spas, museums, schools, gyms, etc.


Crawl space whole house dehumidifier



If your primary reason for searching out a wall mount dehumidifier is not aesthetics, can purchase a crawl space dehumidifier complete with a pump and drain hose for a third of the price.

And have a much more powerful dehumidifier they can handle up to 6,000 square feet.

And Commercial dehumidifiers are usually mounted using a hanging kit.

Not exactly the same as mounting it on a wall, but if you’re willing to think outside the box, and the look of it is not your primary issue,

Then you could have a much better dehumidifier and still be able to keep it off of the floor and out of the way.


Colzer crawl space commercial dehumidifier

This dehumidifier comes complete with a pump and a drain hose and is able to pump out a hundred 45 pints a day.


Alorair Sentinel HDi65

Alorair is warrantied for 5 years.

18000 CoVac BTU Ductless mini split with Cooling Heating and Dehumidifier

Humidity control is not the only issue that people have to deal with when they are trying to control the climate in thier basement.

Finding a way to efficiently heat and cool a basement can be just as much or even more so of a problem then reducing humidity.

Mini split air conditioners are the equivalent of having a HVAC specifically for the room they are placed in. Which means they automatically dehumidify as they cool.

And for much less than the price of a commercial in wall dehumidifier or a wall adjacent dehumidifier,

You can control the overall humidity plus the temperature in the basement and still keep it wall mounted and out of the way.

If you have one of the rare basement setups that offers a window big enough for a window air conditioner, then controlling the humidity in your basement can be as easy as putting a window AC in the window.

Unfortunately this is only an option if you have a window that can fit a window AC in your basement. Most basement windows are narrow and it is almost impossible to find a window AC that is made for a narrow basement window.

Window air conditioners are featuring heat as a standard part of operation more and more.

Just like in the case of a mini split, if you have a window in your basement, a window air conditioner can double as a dehumidifier and heater.


Koldfront Wac 12001W 12000 BTU

This s a window air conditioner / heater / dehumidifier that can heat and cool a spaceship to 550 square feet. It’s dehumidification capacity is 60 pints per day.

LG electronics 8000 BTU heat and cool window air conditioner

This unit is Wi-Fi integrated and can work with Amazon Alexa and hey Google using voice commands.

It cools up to 320 square feet and has the optional supplemental heat setting to help heat your room on cooler days.

This unit is very well reviewed. It has been said to be very quiet and very economical compared to a central heat and air system.

The humidity in the basement and the rest of the house for that matter can all be reduced significantly through encapsulation and the use of a crawl space dehumidifier.

If you have a crawl space, then crawl space encapsulation is a much better option then trying to reduce the humidity inside of the basement via a portable dehumidifier.

The price may be a little more upfront, but it will pay for itself in energy savings and reduced maintenance on your house.

Considering the asking price for some of these wall mounted and in-wall dehumidifiers,

The price of encapsulating your crawl space and keeping a dehumidifier there is really not all that outrageous.


Wall mounting a dehumidifier doesn’t exactly come with a lot of easy options.

Reasons why people want to mount a dehumidifier to the wall are to generally to get it off of the floor and out of the way and or to get rid of the big eye sore if having a boxy dehumidifier with a garden hose attached to it running out of the house.

Desiccant dehumidifiers are inexpensive and come in small wall mountable units. And work great in smaller areas like bathrooms and closets.

But once you move in to a arena where you need much more dehumidifying power, like a basement,

The options become much more costly.

In wall dehumidifiers are a good option but they do require installation.

Other commercial options like EBac AD85OE look great and can easily blend in any room and have the look of a hotel air conditioner.

But you will pay substantially for those aesthetics.

If aesthetics, on the other hand is not the most important issue,
And if you’re only wanting to get it out of the floor because it’s a tripping hazard,

Crawl space dehumidifiers can reduce the amount of moisture for a fraction of the price. And they come with their own hanging system to keep them off of the floor.

Basements with window access can use a window air conditioner two double as a dehumidifier.

Most window air conditioners come with a dehumidifier setting so that you can run the dehumidifier without the cool running also.

Window air conditioners or also starting to feature Heating as well.

Mini split air conditioners or installed with the compressor outside.

But they are wall mounted and look great, and they also double as a dehumidifier.


If you’re going to go down the road of an expensive in wall system, then might want to consider crawl space encapsulation,

which could eliminate the need of a dehumidifier in the house or basement. And make mounting a dehumidifier completely unnecessary.

But before you go down the road so to speak:

Before you buy any expensive equipment or have any work done to close off your crawl space,

It’s important to figure out why you’re having the issue with high humidity in the house in the first place.

Leaking pipes can create a ton of moisture beneath the house that can radically increase the amount of humidity you have inside of the house.

And leaking pipes are something you’re going to have to fix regardless.

Fix the pipes first and you may not even need a dehumidifier.

Another thing that often causes heavy moisture beneath the house is gutters that do not lead rainwater far enough away from the house for it not to River down into the crawl space.

Making sure that you do not have any water from the gutters or sprinklers making its way down beneath the house is also another easy thing you can do that can reduce your indoor humidity.

Bathroom Dehumidifier – What are the Best Options?

Bathrooms are typically one of the most humid rooms in the house. And it’s no mystery why. The shower creates a huge amount of moisture each and every time it is run.

But unchecked humidity in the bathroom will eventually lead to mold growth.

And though mold in the shower is easy to see, it’s all the other mold growing in dark spaces as well as on your towels, toothbrushes, and other items in the bathroom that makes it so disgusting.

Not only disgusting, damaging.

Mold can do a huge amount of damage and in a very short time. Areas like window frames and drywall can experience mold rot very quickly when mold is left to increase.

If you have a bathroom that doesn’t have an exhaust fan or maybe it does but it just can’t keep up with the level of moisture and condensation that you seem to be experiencing,

There is an option that will help reduce the humidity in your bathroom and it’s one that doesn’t carry that high of a price tag.

What I’m talking about is a small bathroom dehumidifier.

Do dehumidifiers work in bathroomsDo dehumidifiers work in bathrooms?

Dehumidifiers work well in bathrooms. Not only does a dehumidifier easily reduce the moisture in the bathroom,

Being close to a sink or shower makes the maintenance of emptying a dehumidifier or running a continuous drain hose much easier.

Bathrooms in most houses generally do not come in over 40 square feet.

And the smallest portable compressor dehumidifiers typically cover around 250 square feet.

So a dehumidifier can keep the air in the bathroom very dry.

Will a dehumidifier keep mold from in the bathroom?

A dehumidifier will help keep mold from growing because moisture in the air is essential for mold to take root.

And that is exactly the point of a dehumidifier, to remove moisture from the air. 

But If you want to eliminate the chances of mold growing in your bathroom, you will have to address other standing water issues on a regular basis as well as running a dehumidifier.

What is the best dehumidifier for a bathroom?
In our opinion the best bathroom dehumidifier is the Medea 1500.

It is not only small enough to completely dry out a bathroom, it is large enough to use in a laundry room, bedroom, or kitchen.

It also has a built-in pump and a washable air filter. A couple of things hard to find on a small bathroom dehumidifier.


Being such a small room, the bathroom actually has a few good options for what you might consider to be the best bathroom dehumidifier.

The first option

Desiccant Bathroom Dehumidifiers


Desiccant humidifiers come in small mountable units that can be placed on the wall out of the way.

  They do not require the typical maintenance of emptying a dehumidifier. Nor do they have to have any type of pump or garden hose ran to them.

The only maintenance is that they are recharged once every couple of months.

These small bathroom dehumidifiers are perfect for helping dry out a medium to a small amount of humidity.

They are all so perfect for closets, pantries, and other small areas

The downside is there is no measurable way to reduce the humidity.

So they will require a separate hygrometer to actually keep tabs on the humidity level inside of the bathroom.

1. Eva-dry E-500 Renewable Mini Dehumidifier

Eva dry dehumidifiers are completely silent, have a 10-year lifespan, and do not require any refills whatsoever.

These are small absorbing dehumidifiers that are designed for small spaces like closets and safes, and might require more than one unit for a bathroom.

These units can absorb up to 8 oz of moisture without any of the maintenance and canister emptying annoyances of compressor dehumidifiers.

2.Pro Breeze Wireless Mini Dehumidifier

Very similar to the Eva dry. These mini dehumidifiers are inexpensive and can make a big difference in a musty bathroom.

Pro breeze can remove moisture in areas of the 333 cubic feet up to 1 month before recharging.

They are safe, space saving, non-toxic devices they can be used in larger areas like a bathroom or much smaller areas as small as a gym bag.

These are very small dehumidifiers that are meant for areas with only mild humidity problems.


Damprid is a container that comes in various sizes of silica gel. It can also be purchased in hanging bags.

One variety of Damprid contains activated charcoal which is very good at getting rid of musty odors.

Damprid is a good solution for absorbing excess moisture in a bathroom. And it can be placed out of sight very easily.

Desiccant Dehumidifiers will need a hygrometer to be able to measure the humidity in the bathroom

4. Govee WiFi Thermometer and Hygrometer

The Govee is a Wi-Fi thermometer/ hygrometer that can hook up to your Wi-Fi or through the Bluetooth.

It has multiple alert functions that you can set up to keep you aware of any changes in your temperature or humidity and be able to react quickly when one or the other falls out of range.

It also keeps a record of your data up to 2 years and can be exported in CSV format entirely for free.

 5. JEDEW 2-Pack Mini Hygrometer Thermometer

If you just need to know the relative humidity and the temperature of the room but you don’t necessarily want or need alerts coming into your phone,

Then JEDEW is a super basic gauge that does just that.

These thermo-hygrometers are very sensitive and measure the humidity every 10 seconds.

They work with temperatures from 32 to 152 degrees Fahrenheit and relative humidity levels from 10% to 99%.

A small portable bathroom dehumidifier

A mini dehumidifier works exactly the same way as a full size portable dehumidifier.

The only difference is that it is much smaller and works in a smaller room.

And even though these dehumidifiers are small, they still can dry out the air in a room that is 250 average square feet.

That means you will not have any problems drying the air out in a room the size of a bathroom.

And it also means that you will have a great small dehumidifier to use in your laundry room, kitchen, or bedroom.

The benefit of using a traditional bathroom dehumidifier is that they or much more exact and can be set to reach a specific humidity level when desired.

They also have features like Auto shut off when the tank is full, and humidistats to shut the machine off when the desired relative humidity is reached.

There is maintenance involved in the form of emptying the bucket when it is required.

But there’s also the option of hooking a continuous drain line in order to avoid ever having to empty the machine.

But just like a humidifier, they have to be cleaned regularly to avoid mold and bacteria from taking root in them.

1.Pro Breeze electric dehumidifier

Pro breeze also has an electric dehumidifier they can cover up to 215 square feet.

It is capable of removing up to 9 oz. of water a day and has a 16 oz/ tank capacity.

Very compact and lightweight, it can easily sit on the bathroom counter.


It doesn’t have drain hose capacity. But since it is intended to be used in the bathroom, there is very easy access for emptying the canister.

2.Levoair Dehumidifier

A very small dehumidifier that features a drain hose.

This little dehumidifier can work in areas of 333 square feet.

It is whisper quiet. Because it does not feature a standard compressor which is the reason most dehumidifiers are so loud.

It is a portable handle and is leak proof.
Which means you can carry it from room to room without spilling.

Built-in drain hose means you can run it without having to empty it.D

3.Beyn Mini Bathroom dehumidifier

Beyn is an extraordinary very attractive dehumidifier that comes with a removable water tank or an optional drain hose. It covers 269 Sq. Ft.

It is lightweight and portable and comes with automatic shut-off to provide you with the security of knowing that it will not overflow when it is full.

The optional drain hose will allow easy drainage into your sink.

This is a very well reviewed product.

The only downside is that it will require an elevated shelf to sit on because it is gravity-based.

4.Midea 1500 square foot dehumidifier

Portable dehumidifiers can take up very little room in the corner of a midsize bathroom.

But they can reduce a significantly larger amount of moisture. And they can easily be used in other areas besides the bathroom.

The Midea 1500 filters the air as it needs humidifiers and can do so in a room 1500 square feet.

It features:

  • Auto restart for power disruptions
  • Optional drain hose capacity.


5.Whirlpool 40 Pint Portable Dehumidifier with Built-in Pump

Q & A

What can happen if you have excess humidity in the bathroom? Mold, damage?

Having excess moisture in the bathroom can cause a lot of damage. Specifically mold damage.

When you’re having a problem with excessive moisture in the bathroom, you will eventually discover that you have mold growing.

And when it becomes visible in the shower, you can be sure that it has found a whole host of dark places to take root as well.

High unchecked humidity in the bathroom will eventually lead to mold feeding on your wood surfaces, window frames, baseboards, etc. and can lead to significant damage.

Other areas you may find mold growing:

  • Ceiling tiles, wall tiles
  • Carpet and rugs
  • Gypsum board (drywall) and the insulation inside the walls. Drywall typically bows out when it’s full of moisture and the paper begins to peel.

Once mold has become a problem in the bathroom, the spores from the mold will be everywhere from your towels, toothbrushes, as well as your pillows and bedding if your bedroom is adjacent.

When do you need to use a bathroom dehumidifier? Winter, summer?

The summer months news typically when you find the higher levels of humidity outside and when you have the most problems controlling the humidity inside.

But humidity inside of the bathroom can be an issue in the winter also when the outside air is cold and it is coming in contact with the warm inside air via the window.

You have probably noticed condensation on your windows during the winter.

The condensation will lead to mold just as fast as any other type of moisture.

So controlling the humidity in the bathroom can be a all year endeavor

Where would you put a dehumidifier in the bathroom?

  Finding the space in a bathroom for a dehumidifier is not the easiest thing to do, especially if you, like me, live in a house with a lot of females.

The ideal spot for a dehumidifier in a bathroom would be on an elevated spot on the sink countertop.

That way you could run a small hose to the sink from the dehumidifier and not have to continuously empty it.

The same concept would work well for the shower too. An elevated spot next to the shower would give you excellent access to either emptying the dehumidifier we’re running a continuous drain hose to the shower drain.

  Desiccant dehumidifiers come in small portable units easily hung on the wall next to the shower.

Desiccant dehumidifiers do not extract nearly the amount of water as a traditional mini compressor humidifier, so using more than one in the bathroom is a good idea.

Does a bathroom dehumidifier use a lot of electricity?

The amount of electricity that a bathroom dehumidifier uses depends on the level of humidity and the runtime of the dehumidifier to extract the humidity everyday,

You can expect a small dehumidifier to use as much as 30 Watts and a larger dehumidifier to pull as much as 70 Watts.

How loud are bathroom dehumidifiers?

Bathrooms are pretty loud spots in my house, it’s not uncommon to hear the radio blasting, shower running, and hair dryer is going at the same time.

  Dehumidifiers can be compared to the level of noise you would get from a window air conditioner. Around 65 db.

Pretty loud. 

But the bathroom is not exactly in use as much as the living room or a bedroom.

What’s the difference between desiccant bathroom dehumidifiers and mini dehumidifiers?

Desiccant dehumidifiers absorb humidity much like a sponge. They also never have to be emptied or run with a continuous drain hose.

They are also much quieter.

Desiccant dehumidifiers for small spaces like bathrooms and closets, or easily mounted to the wall or hung from a hook.

You probably know “desiccants” as the little silica gel packets that come and everything from shoe boxes to keeping gerbil snacks fresh.

Desiccant dehumidifiers are the same concept in a much larger version.

Traditional compressor dehumidifiers extract moisture from the air exactly the way that a window air conditioner does. It pulls air in with a fan, drags it pass a series of condenser coils that capture the moisture and then releases the air back into the room dry.

A mini compressor dehumidifier can extract moisture from a room as big as 200 or even 300 square feet.

That’s much more then you will be able to achieve with a small desiccant dehumidifier.

But there is also maintenance to be considered with compressor dehumidifiers.

If you do not go the drainage hose method, you ‘ll have to empty the bucket for the dehumidifier to run.

And the potential of having standing water is much higher. Dehumidifiers must be cleaned often to avoid mold growing in the machine.

They can also be quite loud.

But One mini portable dehumidifier is big enough to use in the bathroom, bedroom, laundry room, and kitchen.

 Will a dehumidifier soak up water?

A dehumidifier will make it easier for water to dry and is often used to help clothes to dry faster on hangers.

But it is primarily a device to remove moisture out of the air.

Although it will help considerably to reduce the capacity for mold to grow, it will not soak up standing water, nor will it wipe down or squeegee off shower walls, or condensated windows.

Bathroom dehumidifier versus an extractor fan

Installing a dehumidifier is as simple as plugging it in and turning it on. But you will have to empty the bucket on a continual basis and keep the machine clean.

Which to be fair is a much easier endeavor when you are next to a sink or a shower.

On the other hand, a humidity extractor fan just has to have a switch flipped on. No other maintenance involved.

But installing a humidity extractor fan will take much more than plugging it in.

It will require cutting a hole in the ceiling, and hardwiring it into your existing electrical grid.


Though the bathroom can be one of the most humid rooms in the house

Dehumidifiers are devices that can do a great job of remedying that problem.

Small dehumidifiers that you can benefit from using in your bathroom come in both desiccant and compressor type.

Desiccant dehumidifiers use chemicals to soak up moisture in the air. They are very inexpensive and work well for light to medium humidity.

They are also very safe and require very little maintenance. The only maintenance that you will have to keep up with using a desiccant dehumidifier is keeping it charged.

A small compressor type bathroom dehumidifier uses refrigerator cooling coils to condense the moisture in the air.

The water that is captured through the condensation process either goes into a bucket that has to be emptied or can be drained through a continuous drain line.

Compressor dehumidifiers can extract much more moisture out of the air then desiccant dehumidifiers are capable of.

Traditional bathroom dehumidifiers also I’m more likely to come with bells and whistles like built-in hygrometers, auto shut off when the tank is full, and auto defrost if the temperature is lower.

Desiccant dehumidifiers will require a separate hygrometer in order to be able to keep tabs on your relative humidity.

What Do the Numbers on a Dehumidifier Mean?-11 Question Set

What do the numbers on a dehumidifier mean?

Dehumidifiers can be a mysterious thing when you first begin to mess with one.
The different settings and symbols and not to mention the numbers can be confusing.

The main number that appears illuminated on a dehumidifier is the relative humidity inside of the room where you have the device.

It’s the number that you are attempting to lower by using a dehumidifier.

According to the national library of medicine-PubMed, 40 to 60% relative humidity is the Ideal moisture level to avoid problems with either high or low humidity.

Are dehumidifiers safe to leave on?

Dehumidifiers are safe to leave on because they almost exclusively come with an auto shut-off that turns the machine off when the bucket or the basin is full of water.

That means you’re not going to come home to a floor full of water if you happen to leave the house with your humidifier running.

Should I run a fan with a dehumidifier?

Running a fan and a dehumidifier at the same time can be advantageous because both the fan and a dehumidifier have a drying effect on the air.

After all, if you have done a recent painting project that you need to dry  faster you would probably put a fan blowing on it to help it do so.

The same goes for drying your hair, if you want to dry it faster, you can sit in front of a fan or better yet use a hair dryer. Which is essentially a hot fan.

A fan will also help move the humid air in a room towards the dehumidifier where it can do its job better.

And the entire purpose of a dehumidifier is to extract moisture from the air to dry it.

Not to mention that the two can be purchased together in one unit.

So there is no conflict in using a fan and a humidifier at the same time.

Should I run a dehumidifier with an air conditioner?

Using a dehumidifier at the same time as an air conditioner can actually help reduce the wear and tear on your air conditioner because even though an air conditioner dehumidifies as it cools,
It has to work harder when the air is extra humid.

Running a dehumidifier can’t take the strain off of an air conditioner and help it cool easier.

But, remember dehumidifiers operate much like a window air conditioner that exhaust heat out of the rear. Which helps with the humidification process but tends to make the room feel a little swampy.

  So if you’re using a portable dehumidifier, the room that you place the dehumidifier on is not exactly going to feel cooler even though the air conditioning may be working better.

How to know if you need a humidifier or dehumidifier?

If you live in an area that is typically dry, then higher humidity is easy to identify. Your skin is clammy and your hair is frizzy.

But if you’re used to living in an area where high humidity is part of the climate, you may not even be aware that your humidity is spiking.

A hygrometer is a gauge that is designed to tell you what the relative humidity is inside of a room or your house.

If the humidity inside your home is above 60%, then running a dehumidifier is needed to bring that number down below the 60% mark.

Honeywell Small Room Dehumidifier

Is it okay to sleep in a room with a dehumidifier?

Sleeping in the same room as a dehumidifier doesn’t have any adverse effects health wise, there is no threat of dehydration or anything that will harm you but..

Dehumidifiers can be compared to running a window air conditioner. If you’ve ever walked behind a window air conditioner, you probably remember feeling the heat coming off of the rear of the machine.

Dehumidifier works much the same only the heat that comes off the rear of it does not expel outside but inside of the room.

Dehumidifiers are also not the quietest of devices.

Technically there’s no problem with sleeping with a dehumidifier in the same room,

But you may be looking at a swampy feeling, loud night.

What’s better: a dehumidifier or an air purifier?

Dehumidifiers and air purifiers both reduce allergens.

Dehumidifiers reduce humidity problems like high dust mite populations and mold growth which results in high populations of mold spores.

These devices, by reducing the humidity, reduce the allergens caused by the humidity.

Air purifiers reduce allergens by filtering them out of the air.

And they do so regardless of whether the humidity is high or low.

Air purifiers are not dependent on the humidity being at a certain level for them to do their job whereas a dehumidifier is useless when the air is dry. Which is about half the year.

Which is better? A dehumidifier or an air purifier? An air purifier is more useful throughout the year than a dehumidifier.

But it is definitely better to own both and use a dehumidifier when needed.

When should you not use a dehumidifierWhen should you not use a dehumidifier?

Dehumidifiers or devices meant to extract moisture out of the air when the humidity level is too high inside of a house.

If the humidity in the home is already at the optimal level of between 40 and 60%, then you should not use a dehumidifier.

  Another issue that can interfere with a dehumidifier that can keep you from using it is lower temperatures.

As you probably will know if you have read the rest of this article, dehumidifiers run very similarly to window air conditioners that use refrigerant to condense the humidity out of the air.

Just like on an air conditioner, if the temperature is too cold, the condenser coils on a dehumidifier will freeze over.

There are many dehumidifiers that come with a defrost setting for this very problem.

There are also dehumidifiers called desiccant dehumidifiers that do not use a compressor at all. Though not as powerful at removing moisture from the air, it can be a good alternative if your primary issue with humidity is during the cold season.

How long should you leave a dehumidifier on?

40 to 60% humidity is the optimal humidity inside of a home or building according to the national library of medicine.

If you are using a dehumidifier to bring down the moisture level inside of your house, then you should be prepared to leave it on till you have reached the relative humidity of 60% and below.

ThermoPro TP50 Digital Hygrometer

Do humidifiers make the room colder?

Dehumidifiers can have a cooling effect on a room when the temperature is not too hot and humidity is the main thing that is making the room uncomfortable.

But unlike an air conditioner or a fan, the dehumidifier is better left to run before you are planning on using the room.

Even though in theory, you are lowering the humidity which is the main threat to your comfort, The heat that expels from a dehumidifier will have the opposite effect of making a room cold while the dehumidifier is running.

Should a dehumidifier run constantly?

There are times when the humidity is so high that a dehumidifier may seem like it constantly runs and never turns off.

For instance, running a dehumidifier in a crawl space or a humid basement will require a humidifier to run much longer to reduce which is essentially an everlasting problem.

On the other hand, if the humidity level in a room does not warrant the use of a dehumidifier, then the dehumidifier may run constantly because it can’t extract enough humidity to ever reach the point where it shuts off.

  That also answers the question of why your dehumidifier may not be collecting any water. There is simply not enough humidity for it to do so.

But if the relative humidity is high, and your dehumidifier is not collecting any water, you have definitely ruled out the relative humidity being a problem, and can focus on the issue being a mechanical problem with the device.
