Finding the Right Size Humidifier for Maximum Comfort

A humidifier is a useful appliance that can add much-needed moisture back into dry, heated indoor air. Maintaining proper indoor humidity levels between 30-50% has many benefits – it alleviates dry skin, sinus congestion, and static electricity, protects wood furniture and houseplants, and creates a generally comfortable environment.

However, choosing the right size humidifier for your room is important. A unit that is too small will not be able to keep your air properly humidified. On the other hand, one that is too large may over-humidify your space and encourage mold growth. The key factors that determine what size humidifier you need are room size, desired humidity level, and mist output.

This comprehensive guide will walk you through how to calculate the ideal humidifier capacity and output for any residential space.

We’ll cover how cubic feet and humidity needs determine size, compare warm vs cool mist options, discuss key features to look for, and provide tips for proper placement and maintenance. With the right information, you can ensure you select a humidifier that efficiently hydrates your indoor air without becoming an overflowing, leaky nuisance.

Factors That Determine What Size Humidifier You Need

There are several variables that influence what size humidifier is required for a given room or open area. Taking these factors into account will help you choose a model with ample misting power to humidify your space optimally.

Desired Humidity Level

The ideal indoor humidity range for comfort and health is 30-50%. Levels below 30% tend to worsen respiratory issues, cause dry skin and sinuses, and build up static electricity. Over 50%, moisture encourages mold, bacteria, and pests.

A humidifier that is undersized for your room won’t be able to maintain sufficient humidity. Checking the target mist output (in gallons/day) specified by the manufacturer is the best way to ensure the humidifier can hydrate air to your desired humidity percentage.

Use a hygrometer to monitor the current relative humidity in your room before purchasing a humidifier. Keeping it between 30-50% by adjusting your humidifier’s settings prevents under or over-humidification.

Room Dimensions

Naturally, larger spaces require more humidifying power than smaller rooms. To choose an adequately sized unit, you first need to measure your room and calculate its square footage and cubic feet.

Use a tape measure to find the length, width and height of the room in feet. Multiply these three dimensions together to determine the room’s total cubic feet.

Length x Width x Height = Cubic Feet

As an example, a bedroom measuring 10 x 12 feet with an 8 foot ceiling would be:

10 x 12 x 8 = 960 cubic feet

In general, the more cubic feet your space has, the more misting capacity it needs to maintain humidity.

Type of Humidifier

There are several different humidifier technologies, each with their own efficiency and performance. Ultrasonic and warm mist humidifiers tend to humidify large areas better since they produce more mist.

Evaporative humidifiers use wicks and fans to distribute moisture. They work well for small to mid-sized rooms but may not disperse mist widely enough for large open areas.

Knowing the type of humidifier technology and its rated mist output for optimal coverage will help determine if it’s a good fit.

Presence of Doors, Windows and Vents

Rooms with lots of doors, windows or ventilation allow humidified air to escape. More openings mean you need a unit capable of higher mist production to compensate.

Air vents, ceiling fans and other circulating systems also reduce humidity by moving conditioned air out. A powerful humidifier is key for well-ventilated rooms to replenish the lost moisture.

Climate and Time of Year

Dry climates and cold seasons with indoor heat require added moisture. If you live in an arid environment or run your heater often, your humidifier will need to work harder compared to other times of year.

Size up when shopping for a unit you plan to use frequently in dry, winter months. The right capacity helps maintain comfort when your climate works against you.

Calculating Your Room’s Humidity Needs

Once you know your room’s dimensions in cubic feet, you can use some general guidelines to determine its ideal humidifier mist output capacity.

These estimates assume an 8 foot ceiling. Taller rooms require slightly more humidification power.

Let’s refer back to our sample 10 x 12 foot bedroom that had a cubic footage of 960. At that size, it qualifies as a medium room. The ideal humidifier would have around 3-5 gallons per day of misting capability.

Whenever possible, check the manufacturer’s specifications for a given model’s recommended room size suitability and mist output rating. This provides a more exact capacity guide compared to general cubic feet estimates.

Here are two more room size examples with the suitable humidifier output:

• Living Room
  • 14 feet x 18 feet x 9 foot ceilings
  • 14 x 18 x 9 = 2,268 cubic feet
  • Large room over 1,000 square feet
  • Needs 5-8 gallon/day humidifier
• Studio Apartment
  • 300 square feet x 9 foot ceilings
  • 300 x 9 = 2,700 cubic feet
  • Medium room 500 – 1000 square feet
  • Needs 3-5 gallon/day humidifier

Factor in Climate and Ventilation Too

Note that these humidity output recommendations assume average climate and ventilation conditions. Particularly cold, dry air or a room with lots of windows or fans necessitates a unit with more power.

It’s always better to size up if you live in an arid region or have high ventilation. You can always turn down the mist level later, but an undersized unit won’t be able to produce enough humidity for large, dry spaces.

Warm vs. Cool Mist Humidifiers

Humidifiers come in two main technologies: warm mist and cool mist. Let’s compare their operation and ideal room size uses.

How Warm Mist Humidifiers Work

Warm mist units work by boiling water and releasing the steam into the air. The heat involved kills up to 99% of mold and bacteria in tap water, making warm mist models a good choice for allergy sufferers.

On the downside, the hot steam and surfaces can pose a safety risk, especially around children. They also consume more electricity.

Best Room Size for Warm Mist Models

Thanks to their robust steam output, warm mist humidifiers work well for large spaces starting at 1,000 square feet or more. The heat output also helps add comfort in cold climates. Just take safety precautions if kids or pets are present.

How Cool Mist Humidifiers Work

Cool mist humidifiers don’t heat the water. Instead, they use wicks, filters, and fans to evaporate room-temperature water into a fine mist. Other “filter-free” models use ultrasonic vibrations to generate a micro-fine vapor that efficiently humidifies.

Benefits include being safer around kids and pets and using less energy. However they are prone to more mold growth without hot steam to kill bacteria.

Best Room Size for Cool Mist Models

Ultrasonic and evaporative cool mist humidifiers work well for small to medium rooms less than 1,000 square feet. Quiet ultrasonics can even treat larger spaces, but may need frequent refilling.

If you have a nursery or kid’s room, opt for a cool mist to avoid accidental burns. Just be diligent about cleaning it often.

Other Important Features to Consider

Beyond basic warm vs cool mist types, also compare features that affect performance and convenience.

• Runtime Per Tank Fill – Units with a larger water tank capacity need less frequent refilling. If you don’t want to be constantly topping it off, choose a humidifier that can run at least 24 hours before needing a refill.
• Tank Capacity – Check tank size in gallons. Bigger is better for larger, drier rooms. Humidifiers with 1 gallon tanks are suited for small to medium rooms. Go larger for open concept areas. Some humidifiers come with optional extended tanks you can purchase separately for even more runtime between refills.
• Noise Level and Sleep Mode – Ultrasonic and warm mist options are the quietest humidifier types. If the unit will be used in a bedroom, look for a sleep mode that dims lights and reduces fan noise.
• Filters: Washable vs. Replaceable – Replaceable filters last longer but cost more over time. Washable ones save money but require more frequent cleaning and replacement when they wear out. Either type works for general home use.
• Controls and Humidistat – Digital controls allow setting a precise humidity percentage. Models with a built-in humidistat automatically shut off when the desired level is reached, preventing over-humidification.
• Special Features – Consider convenient extras like aromatherapy trays for adding essential oils, air purifying filters, night lights or humidifier/sound machine combos. These may come in handy for nurseries and kids’ bedrooms.

Proper Placement and Maintenance

To function safely and effectively, humidifiers require the right placement and regular cleaning and maintenance:

• Place on an elevated, hard surface at least 2 feet from walls/electronics. Keep away from drafts or vents.
• Fill with distilled or filtered water to prevent mineral buildup. Avoid untreated tap water.
• Change water daily and clean all parts thoroughly. Disinfect with bleach solution weekly to prevent mold.
• Replace filters, membranes, and wicks per manufacturer schedule.
• Let unit dry out between uses to extend lifespan. Store with no water during off seasons.
• Use a hygrometer to monitor humidity and avoid over-humidification. Keep around 30-50%.
• Clean hygrometer sensor regularly for accurate readings.
• Descaling solution removes mineral deposits if tap water is used.

With regular cleaning and detergent-free water, a cool mist can safely humidify a nursery. Just monitor humidity closely and empty water daily. Warm mist models are lower maintenance but too hot for baby rooms.

Where Should You Put a Humidifier When You’re Sick?

If you’re using a humidifier while you’re sick, placement becomes even more important. Set it up on a stable, elevated surface near where you sleep or rest — usually a nightstand or dresser — but keep it at least 2 feet away from your head to avoid direct mist. Make sure the mist disperses evenly into the room and isn’t blowing directly at your face. Proper placement helps relieve congestion and keeps humidity levels balanced for better healing.

Conclusion

Choosing the ideal humidifier starts with calculating your room’s cubic feet and understanding the factors that determine required mist output. Compare manufacturer specifications for models rated for your room size and desired humidity level.

Cool mist works well for smaller areas under 1,000 sq ft, while warm mist better serves large open spaces and cold climates. Consider convenience features like runtime, controls, and noise level too.

Proper placement, daily cleaning, and monitoring humidity prevents issues like leaks and over-humidifying. Maintaining your humidifier well also extends its functional lifespan.

With the right sized unit for your needs, you can enjoy balanced humidity between 30-50% all year long. This protects your home, possessions and health without promoting mold growth. Breathing properly humidified air feels fresh and soothing.

I enjoy plants. I get a real jolt out of seeing plants and flowers that I have potted and kept up with the watering, thriving and growing, big and luscious.

I also have a couple of excellent areas where I put my plants that they seem to grow like crazy in.

One being the window sill in the kitchen,

and  the other one being a bathtub (it’s a ridiculously small bathtub, I don’t know what the builders of the house were thinking when they put it in)

that sits underneath a skylight in the bathroom.

Both of those areas work well for growing because of their easy access to water and direct sunlight for 4 or 5 hours a day. Not to mention the amount of humidity in those rooms.

But I also have a room where even though it gets a lot of sunlight, it is very dry and a pain to carry water in there  to take care of the plants.

I know that makes me sound lazy, but there is a big difference in taking care of plants when you have easy access to water. Take it from me.

My Plant Humidifier Experience

Recently I decided to go the humidifier route, with the plants in that room.

After all, it only makes sense.

When you compare that room to the other rooms where we keep plants, there’s an obvious difference.

The plants in the bathroom and in the kitchen both get a lot of humidity.

Bathrooms are naturally humid because of the showers going on and kitchens also get their share of humidity from the kitchen sink.

So putting a humidifier in the other plant room to keep moisture in the air seemed like the perfect ideal.

So what did I learn from it?

Are humidifiers good for plants?

Putting a humidifier with my plants works pretty well. Does it transform that area into a greenhouse? Not exactly. But it does make a difference.

The plants seem to be a little greener from just having a little humidity settling on them.

They have that vibe of being happy and healthy, the way they’re reaching for the sky..

I told you I like growing plants.

Do plants need a cool or warm mist humidifier?

I originally used a vaporizer because we just happen to have one in the closet.

And it made sense that tropical plants probably like hot humidity because of their natural habitat and what.

It also seemed like a good idea because the water in the vaporizer was being boiled which means less chance of mold and bacteria growing in it.

Both of those assumptions were true.

But nevertheless, I decided to take out the vaporizer and put a cool mist humidifier in there instead ,because the vaporizer was making the room feel too swampy.

Did I see a difference in the plants by swapping out the vaporizer with the humidifier?

No I didn’t. I’m guessing humidity is humidity no matter what the temperature is.

When should I use a humidifier for my plants?

Some of the other particulars like when and how, I just Googled them.

In Particular, I needed to know when to use it and where to put it.

I needed to know when the actual humidity in the house warranted using a humidifier and I needed to know when, as in what time of the day to use it.

What I found out about “when to use it” made perfect sense when I heard it.

The ideal is to run the humidifier in the morning before the sun shines directly on the plants.

That probably all depends on which room you’re putting them in and what time the Sun shines into that room.

The Sun hits my room in the afternoon, so running the humidifier in the morning is better for me.

The main reason and why it makes so much sense is that if you are running your humidifier at the same time that the Sun is directly hitting your plants,

The condensation that the humidifier creates can have a magnifying glass effect which can cause the sun to burn your plants.

The same reason why they say not to water your grass in the afternoon sun.

Told you it would make sense when you heard it.

As far as the humidity level in the house, it turns out that plants are very similar to humans in the level of humidity that they find most beneficial.

Though some tropical plants need more humidity, most plants thrive best when the humidity in the house is between 40 and 60%.  Other plants like succulents prefer desert conditions so a humidifier is pretty useless for growing cactus.

How do you know what your humidity is?

A little device called a hygrometer. It’s also called a humidity gauge or a humidity meter.

As a standalone device, they’re pretty cheap. Around the $20 mark.

But you can also buy a humidifier that has a humidity meter built in. And a humidistat to control when the humidifier comes on and turns off according to the relative humidity of the room at any time.

A much more convenient option.

Where do you place a plant humidifier?

The other thing I needed to know was where to put the humidifier in relation to the plants.

The answer I found when I Googled this didn’t make as much sense to me.

It’s  because I would think that plants would love the feeling of having condensation on them.

Since, especially when you’re talking about tropical plants, they are used to having the rain pour down on them.

But the experts say that putting the humidifier too close to your plants can cause them to become limp and mushy.

This probably warrants experimenting.

I think I’m going to have to feel this one out a little longer, because with the amount of sunlight coming into that room, I haven’t noticed any mushiness in my plants.

Plant Humidifier Drawbacks

The main drawback is the maintenance required for the humidifier itself.

Not only is keeping it filled with water a drag, it also has to be cleaned weekly to avoid mold and bacteria growing in it.

So if you are shopping for a humidifier, I suggest you find one that has a big tank that doesn’t require refilling as often,

And find something that is easy to clean. Dishwasher friendly.

Recap

A humidifier for your plants is a great idea.

What better way to simulate the natural habitat of a tropical plant than to add moisture into the air with a humidifier?

Just remember that humidifiers require  some work. They have to be refilled and cleaned fairly often.

And there are some rules about when and where you want to put it. Like when to use it and where to put it.

And if you are shopping for a plant humidifier,

A few tips you might want to consider are:

1. Find one that’s easy to clean.
2. Find one that is big enough to run a long time without having to refill it.
3. Get one with a humidity meter( hygrometer) so you can make sure you’re running when you need it and not when you don’t.
4. And remember you can always go the vaporizer route to minimize  the cleaning.

Better yet, get a humidifier that can function as a cool mist humidifier or a warm mist (vaporizer).

Humidifiers have traditionally been a congestion and dry nose device and something that may not come to mind immediately when you’re thinking about moisturizing your skin.

But lately, humidifiers are as likely to be found in the beauty section as much as they are in the seasonal cold and flu section.

Why is that?

It comes down to the science and a level of understanding of how the relative humidity at any given time can be at the root of dry skin.

Though it is well known that not all skin types are the same and some people have naturally oily skin and some people not so much.

But regardless of skin type, dry skin as it is related to humidity, is basically dehydrated skin.

Dry skin = dehydrated skin.

Hadley King, MD states “dry conditions can cause small cracks on the epidermis that expose nerve endings and the deeper layers of skin to the outside world”
“Increasing moisture levels helps to maintain hydration. When skin is properly hydrated it naturally combats common winter skin concerns.”

Does the humidifier help with dry skin?

One of the easiest ways to help combat dry skin as well as being one of the best all natural moisturizers is a humidifier.

Humidifiers have a single purpose. To restore humidity back to the air.

According to PubMed, the relative humidity must be maintained between 40 and 60% to minimize adverse health effects including dry skin.

Humidifier benefits for skin

Keeping the humidity in your home at an optimal level with the use of a humidifier can benefit you and be an integral part of your skin care routine by Supplementing the moisture in your skin when the cold has dried you out and the heater is drying you up.

A humidifier also benefits the skin by keeping dust levels down. When the air is dry, dust floats easily, which in turn contacts your skin much easier, drying it out that much more.

Air that has the right humidity, moistens dust and keeps it from floating.

The relative humidity also keeps allergens and viruses from being able to travel as far. When the air contains the right relative humidity, viruses and allergens, as well as other airborne bacteria, becomes too heavy to float and fall through the surface much faster.

Steam humidifiers can also help open up your pores for deep cleaning.

Facial steam humidifiers hydrate your face and allow you to remove a deeper level of dirt and bacteria from your skin

What’s the best humidifier for skin?

Humidifiers can come equipped with all types of features that were once not heard of in the humidification arena.

But the feature you should be sure to include in the purchase of a humidifier is undoubtedly a hygrometer or hydrostat as it’s also called.

A hydrostat is like a thermometer for humidity. It tells you exactly how humid the air is and allows you to set it dial in the relative humidity level that you want it to be.

Without a hydrostat/hygrometer you have no way of knowing how much humidity you need or even if you need it at all.

Another feature that you should look into when purchasing a humidifier is the capacity to run as either a warm mist humidifier or a cool mist humidifier.

Both have their advantages.
For instance a cool mist humidifier may offer more relief for a dry throat and dry nasal passages. They are also infamously endorsed as a better option for cold symptoms or congestion and sore throats by Mayo Clinic.

Cool mist is also recommended for children because it doesn’t offer any risk of getting burned and when you’re sleeping with the humidifier running for relief during the night, steam is not something you’re looking for.

But on the other hand, steam humidifiers have other benefits like helping you be able to exfoliate your skin and well with different additives like eucalyptus that can help you better also.

So if you can purchase a humidifier that can operate as both a cool mist and a steam humidifier, that’s the direction to take.

Another thing you should keep in mind when purchasing a humidifier is that they require regular cleanings to keep them from becoming a point of origin for bacteria and mold.

There are many humidifier brands these days that make the process of keeping the humidifier clean much easier and less frequent.

Humidifiers like the Dyson AM10 use ultraviolet light to target bacteria and mold inside of a humidifier basin, while other humidifiers like the Taotronics use antimicrobial plastic in their construction to keep mode from being able to grow inside of the unit.

There are also different types of additives like Guardian Aquasticks you can put directly into the humidifier basin to keep mold and bacteria from becoming an issue as fast.

Wrap up

Humidifier Benefits for Skin

Dry skin and skin care maintenance may not be something you immediately associate with humidity and humidifiers, but the truth is the two actually go hand in hand.

Skin moisturizing should always start with making sure your air humidity is between 40 to 60%. If the relative humidity is below 40%, then your skin can become dehydrated very quickly.

Thankfully, there is an easy solution for dry air. The good ol humidifier.

Only humidifiers these days come with features like hydrostats that allow you to dial in the exact humidity you need.

Not only that, you can purchase humidifiers that can run up to 60 hours without refilling.

Other features like self cleaning technologies and combination hot and cold mist make humidifiers a must have for maintaining healthy skin.

Where to Put a Humidifier When You’re Sick

Experts recommend cool mist humidifiers near your bed (avoiding direct mist) for congestion & dry coughs. Read on for specifics!

According to the Mayo Clinic, a cool mist humidifier works by increasing moisture in the air, which can soothe irritated respiratory passages and make it easier to expel mucus. The moist air also prevents tissues in your nose and throat from drying out, which can worsen coughs and sore throats.

When you’re battling a cold, cough, or congestion, using a humidifier can be a game-changer for your comfort and recovery. Here’s everything you need to know about choosing and using a humidifier to ease your symptoms.

What Type of Humidifier Is Best for Coughing and Congestion?

For coughing and congestion, cool mist humidifiers are generally recommended. They add moisture to the air without heating it, making them safer around children and during sleep. Cool mist options like ultrasonic or evaporative humidifiers are ideal for easing respiratory symptoms.

What to Set Your Humidifier At When Sick

The ideal humidity level in your room should be between 30-50%. Higher levels can promote mold and dust mites, while lower levels might not provide enough relief. Use a hygrometer to monitor and adjust your humidifier accordingly, aiming for the higher end of this range when dealing with congestion.

How Close Should a Humidifier Be to Your Face?

It’s best to place the humidifier about 3-5 feet away from your bed. This distance allows the mist to disperse evenly throughout the room without directly impacting your face, which can cause discomfort or excessive moisture.

Does Sleeping with a Humidifier Help a Cold?

Yes, sleeping with a humidifier can help alleviate cold symptoms. The added moisture in the air can soothe irritated tissues in your throat and nasal passages, making it easier to breathe and promoting better sleep.

When running a humidifier overnight, water quality and humidity level matter just as much as placement. Using mineral-heavy water or letting humidity climb too high can lead to residue, irritation, or discomfort by morning — especially when you’re already sick.

If symptoms seem worse after overnight use, it’s often tied to water choice or buildup rather than the humidifier itself. We explain when distilled water really makes a difference (and when tap water is usually okay) in our guide to using distilled water in a humidifier.

Does Sleeping with a Humidifier Help with Congestion?

Absolutely. A humidifier can help loosen mucus, making it easier to clear congestion. The moist air also prevents the drying out of nasal passages, reducing the stuffy feeling that comes with a cold or flu.

Best Humidifier for Coughing at Night

When choosing a humidifier for nighttime cough relief, look for:

• Quiet operation: Ensures your sleep isn’t disturbed.
• Cool mist feature: Safer and more comfortable for continuous use.
• Adjustable settings: Allows you to control the output for optimal comfort.
• Easy maintenance: Reduces the risk of bacteria and mold growth.

Ultrasonic cool mist humidifiers are often favored for their quiet operation and fine mist, making them excellent for use during sleep.

Why Does my Humidifier Smell Like Fish?

A fishy odor coming from a humidifier is an indication that there is mold and mildew somewhere inside the humidifier. Stagnant water is typically present when a humidifier is smells like fish or urine.

If you have a humidifier that has a unpleasant smell emanating from it, you can be sure a deep cleaning is needed. The humidifier should unplugged and carefully taken apart and washed thoroughly.

You should consider soaking each part in hot water. A dash of bleach added to the water will help kill any lingering bacteria. If you have a humidifier that is dishwasher safe, then by all means, take that route.

Other complaints about odors coming from a humidifier usually are related to the smell of plastic burning or just the smell of burning.

The smell of plastic burning from the humidifier can be the simple smell off-gassing from the plastic heating up for the first few times if the humidifier is new. A smell that should very quickly wear off after a few uses.

On the other hand, is humidifier is not new, then there is a problem with overheating.

In that case, a inspection should be done around the humidifier to see if you find any type of visible burn marks or plastic warping. The power cord should also be inspected to make sure that it is not burning at the outlet.

If there is a problem with the power going to a specific outlet, you can easily plug the humidifier into a different outlet that is on a different circuit and see if you get the same type of burning smell. If you do, then your humidifier is to blame. If you don’t, then your own electrical system is to blame.

Portable humidifiers typically only use about 30 to 50 w. Very little energy, and not enough to trip a breaker. Burning is not natural.

Humidifier Hacks for Smelly Humidifiers

People have tried all types of solutions and additives to put in humidifiers to keep them from smelling and help add a fragrance to the room through the use of a humidifier.

Some make a lot of sense and work great, others not so much.

Caution: Humidifiers have a lot of working parts that need to have a clear pathway for water to flow. Anything you put into a humidifier that can clog up a nozzle for instance is a No-No.

Humidifiers that can be used for aromatherapy and essential oils have a separate compartment to put those items.
The reason is that they are oily and oil does not mix with water.

The result of adding essential oils directly into the water of a humidifier is the likelihood of clogging up the waterways needed inside of the humidifier for it to work properly.

Can you put Vicks in the humidifier?

Vicks is a perfect example of a product that should not be added to the water of a humidifier. The gummy texture of Vicks will clog up a humidifier very quickly.

But on the other hand, if you use a Vicks humidifier that has a separate compartment to put the Vicks salve, then the combination is an excellent means of moistening the air and adding the medicated aroma of Vicks that can help you breathe better and relieve congestion.

“The point is no oily or gummy anything should be added into the water of a humidifier.”

But there are things you can put into the water of a humidifier to help keep the humidifier fresh and clean and also add an extra ambience to a rooms existing atmosphere.

Can I put perfume in my humidifier?

Adding perfume or cologne to the water in a humidifier is a excellent and convenient way to add a fresh scent to the air while you’re humidifying it.

Do not use any type of perfumes that have a oily texture to them though. Most perfumes in colognes are alcohol-based and do not have anything in them that will clog a humidifier.

The caveat of putting perfume in the water of your humidifier is to start off slow and only add a few sprays or squirts and then see what kind of difference it makes. If you need more you can always add a little more. Not as easy to take some out. You’ll end up having to dilute the water by dumping some out which will be a waste of perfume and water.

Can I put bleach in my humidifier?

Adding a small amount of bleach to the water of a humidifier is a great way to reduce the amount of time it takes for mold and bacteria to take root inside of the water basin.
Remember A little dab will do you when it comes to bleach. The ideal is to add only enough bleach to aid in keeping the humidifier cleaner.
Too much can give you a headache and many people are very sensitive to the smell of bleach.

So be cautious not to overdo it and start off very light and only add a little more in steps as needed.

Many humidifiers brands suggest adding a drop of bleach into the water basin of their humidifiers. So it is a common practice.

Can I put lemon in my humidifier?

Lemon is a great additive to put in the water basin of humidifier. Not only does lemon have very many natural cleaning agents in it that will help reduce and keep the amount of mold and bacteria that can take root in a humidifier down, it also will add a fresh lemony citrus scent to your room when the humidifier is running.

Lemon scent is one of the most air freshening and odor killing and reducing scents there is. Many household cleaners come in lemon scent for just that reason.

It only makes sense that adding lemon scent to a humidifier makes good sense.

Can you put vinegar in a humidifier?

Vinegar is a all natural mold inhibitor and mold and bacteria cleanser that makes a great additive to put in your humidifier water.

Vinegar also has its own medicinal properties that can aid in the loosening of chest congestion when you breathe it.

And a lot of people do not realize that in a Coke vs Pepsi type of challenge between bleach and vinegar, the vinegar was better at cleaning mold then bleach. And has a much better success rate at cleaning mold that is below the surface.

How much vinegar do you add to the humidifier water? The answer is two you can smell it. Nobody likes the overpowering smell of vinegar, so starting off small and adding a little till you get just the right amount is the best way to add vinegar to your humidifier.

Can I add baking soda to my humidifier?

Baking soda is a great odor absorbing substance that can be added to the water basin of a humidifier to reduce the musty smells that can come from a humidifier.

Baking soda also has a cleaning element to it that will help break down and rid your humidifier of mold and bacteria.

When it comes to adding baking soda to your humidifier, you should check your owner’s manual because baking soda has an abrasive texture to it and can cause erosion in certain cases.

Can I put vanilla extract in my humidifier?

Vanilla extract should not be put directly into the water of a humidifier because of its oily texture. Oil and water do not mix. The result will be oil clogging up the necessary waterways that your humidifier requires for working appropriately.

Can I put Downy in my humidifier?

Putting Downy in a humidifier will not provide any extra benefit to the humidifier because it is a fabric softener. It will also not add any benefit to the air quality since air lacks the capacity be softened.

But many air fresheners come in Downy smell and any problem that could arise from adding fabric softener to the water in your humidifier is very minimal because fabric softener dissolves in water very well.

Can you put hydrogen peroxide in a humidifier?

Hydrogen peroxide is a inexpensive alternative to adding commercial mold inhibitors to your humidifier water.

On top of being a mold inhibitor and cleaning agent, hydrogen peroxide also has
an enzyme type property that will help eliminate the smell of urine often associated with humidifier water.

One of the Great DIY humidifier hacks is adding a few drops of hydrogen peroxide to your humidifier water every time you fill it up.

Summary

Humidifiers are meant to add moisture to the air as a means of relieving the symptoms that often arrive with dry and arid conditions. But when they add more to your air, as in a fishy, moldy, and even a urine smell, you’ve got a problem with mold and bacteria growing in and around your machine.

But there are solutions to keeping any humidifier smells at bay and getting the right results that were intended with the humidifier in the first place.

The main thing to remember when adding anything to your humidifier water is that it has to dissolve in water and or mix well with water.

Anything that has an oily or gummy texture to it like essential oils or medicinal salves like Vicks can clog up your humidifier and make it ineffectual to do the job of moistening the air it is intended for.

But there are some great additives that you can put right into humidifier water, and most you probably have in your house already.

Many people get great results from putting all natural bacteria and mold inhibitors like vinegar, lemon, and peroxide right into the water basin of their humidifier.

Other items like cologne, perfume, and even fabric softener like Downey can turn the humidifier into an excellent combination air moisturizer and deodorizer.

We hope you found something in this article that you can use or spur your own imagination for ways that you can utilize your humidifier.

Humidifiers are notorious for being high maintenance machines because of the nature of their design and that they require a basin of water to work.

3 different types of Humidifiers that qualify as “self cleaning”:

1. UV sterilization
2. Germ resistant plastic
3. Germ and Bacteria Resistant Water Additives
4. Vaporizer

Why does that make Humidifiers high maintenance?

Because of the easy formation and growth of mold that happens inside of a humidifier when it is not maintained properly.

And the fact that the mold growth inside of the machine becomes part of the humidity being expelled into the room when the unit is in operation.

Breathing mold spores can trigger asthma and exasperate allergies. That’s not good.

Wouldn’t it be great if there was such a thing as a “self cleaning humidifier”?

Technically a vaporizer is a type of Humidifier that is considered a self cleaning humidifier because is boils water as a means of creating steam. The boiling process kills any mold or bacteria in the operation.

But vaporizers are not for everyone and most people considered them to unsafe to keep in the babies room or children regardless.

So where does that leave the idea of a self cleaning humidifier?

There is not yet such a thing as a completely self cleaning humidifier that requires no maintenance.

But there are multiple ways that the issue the mold growth in humidifiers is being addressed, and different technologies that are being invented and used to make humidifiers safer.

1. Antimicrobial plastic

One of the most exciting innovations in humidifiers is the use of germ and bacteria resistant materials in the construction of the humidifier.

Antimicrobial plastic contains biocide polymers that combat the production of mold and mildew on the surface of the plastic. It has a ton of applications and seems to be perfectly suited for humidifiers.

Not only can humidifiers be completely built out of antimicrobial plastic, the filter inside of the humidifier can also be coated with the same type of product to keep the filter from becoming a moldy mess too.

Which, as you probably have already realized, is an amazing leap for appliances like humidifiers and dehumidifiers, as well as air conditioners and water-based air purifiers.

Since the one thing all of these appliances have in common is that they are subject to mold and bacteria growth,

If the materials that the humidifier is constructed of are resistant to mold growth, and the filters within them are also resistant to mold, then the search for a self cleaning humidifier is nearly half over.

Nearly half?

Yes, nearly half. The reason is, that humidifiers not only grow mold on the plastic and construction itself, they also have a tendency to get mold on the surface of the water inside of the basin when it is not changed often.

And keep in mind, the whole point of the humidifier is to use the water in the basin to emit into the air to increase the humidity in a room.

If the water in the humidifier basin has mold and mildew when the machine is running, then the humidity droplets in your air will also be full of mold spores and bacteria.

Keeping mold and mildew from growing on the surface of the humidifier, regardless of it being inside or out, is a mind-blowing advancement in humidifier innovations, but it is yet only half the battle.

Keeping mold and germs from growing in stagnant water is the other side of the equation that would make a humidifier actually “self cleaning”.

2. Ultraviolet sterilization

Fortunately there is already people who are making products to remedy the situation of mold growing on the surface of the water inside of a humidifier.

UV lamps are used in multiple industries to help reduce the spread of mold, bacteria, and viruses.

You have probably seen aquariums with a blue light inside of them. The blue light is a ultraviolet lamp that is targeted on the inside of the aquarium to help reduce the amount of algae and mildew that tends to take over an aquarium pretty fast.

Another place might have seen this same procedure in action is in a barber shop. Barber shops oftentimes have a cylinder that they put their Combs and scissors in that employees a UV lamp to clean and disinfect their utensils while they are not in use.

This is exactly the same way that ultraviolet light can be used in a humidifier.

Positioning a ultraviolet light inside of a humidifier to continuously Target the water inside of the basin is a proven method of reducing the amount of contaminants that may be emitted into your airstream in the humidifying process.

Combining ultraviolet light in a humidifier that is constructed out of antimicrobial plastic seems to cover all the bases in the search for a self cleaning humidifier.

3. Germ and Bacteria Resistant Water Additives

Another technology that is used to combat the production of mold in the water of a humidifier is anti mold and germ pods that you purchase to place inside of the basin with the water.

This is more of a back road country recipe that has become more mainstream.

The ideal is to put an additive in the water that keeps mold from taking hold.
Colloidal silver is a natural antibiotic that also has antimicrobial properties.

Although you can purchase colloidal silver and just add it to the water in your humidifier, you can also purchase pods and sticks that contains silver in them that will do the same thing as adding colloidal silver.

“There is a problem with these additives though, they are only useful in ultrasonic humidifiers.”

Another do-it-yourself home recipe for keeping the water in your humidifier fresher longer is to add a little bit of vinegar to the water in your humidifier.

Vinegar is actually one of the best all natural mold cleaners there is. Even edging out bleach because of its ability to get down under the surface better.

Some people even advocate breathing vinegar steam to get rid of chest and head congestion. But if that is something you want to try, you should do your own research and probably stick with apple cider vinegar which is loaded with enzymes and vitamins.

Recap

There is no humidifier that it is 100% self cleaning. But there are newer technologies available that make it nearly a reality.

Technologies like antimicrobial plastic that resists mold growth can be used in the construction of the humidifier making the materials the humidifier is made out of already mold resisting.

The filters inside of humidifiers can be coded with the same type of polymers that are contained in the antimicrobial plastic, which we’ll also help the filter for becoming a mold farm.

As for the water in the basin, there is a couple of technologies that can help keep the water fresher, longer.

One one is the use of ultraviolet light targeting the surface of the water so that mold and algae cannot take root.

Another is to add anti mold pods that contains silver. Silver is a natural antimicrobial that can help the water in the basin of your ultrasonic humidifier stay safer.

After all the point is to add clean humidity to your air so that you can breathe better.
Adding humidity that is laced with mold and germs is a quick way to trigger allergies and asthma.

Many of the reviews of so-called germ-free humidifiers are negative because people seem to have the expectation that there is no cleaning involved whatsoever. Unfortunately that’s just not the case.

For instance, The main issue with using UV in a humidifier is that the UV light has to be targeted directly on the bacteria or mold to be effective at destroying the germs.

So even though incorporating a UV lamp inside of a humidifier will definitely help cut down on mold and bacteria,

You shouldn’t expect every square inch of the humidifier to be in the direct target of the UV.

Some, like the Dyson a.m. do a much better job then others,

But the idea that you do not have to clean the humidifier ever because it has a UV lamp is not realistic.

The same thing goes for humidifiers that have the antimicrobial silver induced plastic. Do they help reduce germs in the water tank of a humidifier? Yes, no doubt.

But does that mean that there is no cleaning to be done? Not at all. There has yet to be invented an additive but you can place it in a humidifier that will completely kill 100% of all bacteria and mold.

Self-cleaning humidifiers are better called low maintenance humidifiers because they incorporate methods to help curb bacterial growth and reduce the amount of cleaning.

Some are better than others.

But there is no such thing as a humidifier that is completely germ-free.

The reviews are hit-and-miss with a lot of people saying that the humidistat failed fairly soon after their purchase.

Boneco s450

There is a way to bypass all the issues of adding a ultraviolet lamp to a humidifier or putting additives in the tank or purchasing a humidifier that’s made out of antimicrobial plastic,

And that is to purchase a warm mist humidifier that boils the water before it is emitted into the air as steam.

Warm mist humidifiers or vaporizers are not for everyone because steam will raise the temperature in a room.

But as far as warm mist humidifiers go, Boneco has a humidifier that is next level.

Remarks

This is a warm mist humidifier that has all the bells and whistles you typically find with the big brands like Levoit.
Warm mist vaporizers or an easy way to get a bacteria free experience from a humidifier.

But they do use steam to humidify, which can make a room feel swampy.

This is a real nice humidifier but personally I would pick a humidifier that has a cool mist option as well as a warm mist often.
