What do the numbers on a dehumidifier mean? (11-Question Set)

What do the numbers and symbols on a dehumidifier mean?

Dehumidifiers can be a mysterious device when you first attempt to navigate one.

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.

Dehumidifier Numbers and Settings

relative humidity setting on dehumidifierRelative HumidityThe primary figure displayed on a dehumidifier indicates the relative humidity within the room where the device is placed. This is the value you aim to decrease by using a dehumidifier. Maintaining an optimal relative humidity level is essential to prevent issues associated with both excessive and insufficient humidity levels.

How to Find and Set Dehumidifier Settings on an AC

On some air conditioners (AC units), you may find a dehumidifier setting. Here’s how to locate and adjust it:

  1. Look for the remote control or control panel on your air conditioner.
  2. Check for a “Mode” or “Settings” button. Press it to access the different modes or settings available.
  3. Search for the “Dehumidifier” or “Dry Mode” option among the modes/settings. This mode is designed to reduce humidity in the room.
  4. Select the “Dehumidifier” mode and set your desired humidity level if applicable. Some AC units allow you to adjust the target humidity level.
  5. Confirm your selection, and the AC will start operating in dehumidifier mode, helping to reduce excess moisture in the air.

Benefits of Using a Dehumidifier

Maintaining the ideal humidity levels in your home offers a range of advantages that contribute to a healthier and more comfortable living environment. Here are some key benefits of using a dehumidifier:

  1. Improved Indoor Air Quality:

    Allergen Reduction: Dehumidifiers help reduce common indoor allergens like dust mites, mold spores, and mildew. Lower humidity levels make it less hospitable for these allergens to thrive, leading to cleaner and healthier air.

Asthma and Allergy Relief: By minimizing airborne allergens, dehumidifiers can alleviate symptoms in individuals with asthma and allergies, promoting better respiratory health.

Less Odor: Lower humidity levels can help control musty odors often associated with damp environments, ensuring your home smells fresher and more pleasant.

  1. Mold and Mildew Prevention:

    Mold Growth Prevention: Excessive humidity is a primary factor contributing to mold and mildew growth in homes. Dehumidifiers can significantly reduce the risk of mold infestations on walls, ceilings, and other surfaces, protecting your home from structural damage and health hazards.

Healthier Living: Mold and mildew release spores that can trigger allergies and respiratory issues. A dehumidifier can help safeguard your family’s health by preventing the formation of these harmful substances.

  1. Enhanced Comfort:

    Temperature Regulation: Maintaining the optimal humidity level in your home can make it feel more comfortable even at slightly higher temperatures. When the air is less humid, your body’s natural cooling mechanisms, like sweating, become more effective, allowing you to stay comfortable without lowering the thermostat.

Reduction in Stickiness: High humidity levels can make you feel sticky and uncomfortable, especially during the summer months. Dehumidifiers can alleviate this discomfort, making your living space more enjoyable.

Preservation of Belongings: Lower humidity levels can also protect your furniture, electronics, and other possessions from moisture-related damage and deterioration.

  1. Energy Efficiency:

    Energy Savings: Dehumidifiers can contribute to energy savings by making your air conditioning more efficient. When the air is less humid, your AC doesn’t have to work as hard to cool the space, potentially lowering your energy bills.

  2. Structural Preservation:

    Home Maintenance: By reducing excess moisture in your home, dehumidifiers help preserve the structural integrity of your house. High humidity levels can lead to rot, warping, and corrosion in building materials.

  3. Peace of Mind:

    Reduced Health Concerns: Knowing that your indoor air quality is optimal and that mold and mildew growth are being prevented can provide peace of mind for you and your family’s health and well-being.

Are dehumidifiers safe to leave on?

Dehumidifiers are safe to leave on because they almost all 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 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 they are running in 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.

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

Best Water for Humidifier-Distilled, Bottle, Boiled or Tap?

What is the Best Water for a Humidifier?

Distilled water is the best water to use in a humidifier because:

The use of distilled water helps keep your humidifier in good condition. Because of the process in which distilled water is made, It lacks minerals like calcium and magnesium, as well as sodium that can build up inside your humidifier and make it less effective.

Dry air in the Winter causes an array of issues. The skin breaks, the lips shrink and swell, and your nose becomes congested. The worst part is that these issues result from the air you breathe and are surrounded within your home, your own domain.
A humidifier is a device that can help avoid these issues. It can help bring the humidity to a level that is comfortable and much more healthy for the people in your home.
However, there are some disadvantages to using a humidifier incorrectly. It can increase maintenance expenses. It can also affect the quality of air in your home.
If you want to use your humidifier properly, the first thing you’ll need to be aware of is the kind of water you should be filling it with.

Distilled Water for Humidifier

Distilled drinking water is the most suitable kind of water to use in a humidifier. It has been processed to get rid of contaminants like bacteria and minerals. Particles that you do not want in your air or your humidifier.

Think about it…

The bacteria in your water can end up being in the air that you are breathing since it’s going through a humidifier. And Minerals and other particulates can end up damaging your unit and reducing the life of your humidifier.

Distilled water is produced when boiling water evaporates into steam and then cools.  The process causes the impurities in the water to be left behind as it turns into condensation. The condensation is collected and bottled as “distilled water”

Mold Prevention. Mold growing in a humidifier is one the biggest problems people face when using one. Distilled water is less likely to have mold spores present in it. Which will help keep mold and bacteria from taking root as quickly in the humidifier.

Less Dusty Humidifier dust is caused by the minerals that are in tap water and drinking water.  Because distilled water is treated to eliminate the minerals, it will help keep the problem of “humidifier dust” to a minimum.

Tap water in a humidifier?

Tap water for humidifiers is not advised. Tap water is typically a source of solids and minerals that could harm your humidifier. Tap water can result in calcium deposits developing inside of your humidifier.

Utilizing tap water for your humidifier can cause also lower the quality of your ambient air. It is is loaded with chemicals like fluoride that when moved through a humidifier become part of the air you breathe.

Also the white “humidifier dust” that appears on the surfaces around the humidifier can be kicked up into the air. Which will not only inhibit your breathing, will dry out your skin. One of the very things that you wanted a humidifier for in the first place. 

In order for mold to grow, it requires three different ingredients; water, low light, and a food source.

Tap water is loaded with minerals that can be considered the food source for mold to grow.

Though It is recommended to clean or replace the humidifier’s filter frequently and also clean the inside of any mineral build-up, using tap water will increase the frequency of replacing filters and increase your cleaning schedule..

Demineralization cartridges are available on many humidifiers and can be bought separately if you decide that using tap water is worth the risk.

bottled water for humidifierBottled Water in a Humidifier?

Using bottled water in a humidifier is only slightly better than using tap water. It is filtered but not to the point that it is free of the minerals that can cause deposits in your humidifier. 

A lot of bottled drinking water that you find on the shelf is natural spring water or at least that’s supposed to be the origin.

Natural spring water naturally has a lot of minerals and solids that will end up making your humidifier less effective.

If you read the label good on most bottled water, you will see that it says that minerals have been put back into the water for consumption.

But not to the point or the quantity that you will get from just putting plain tap water into your humidifier. So even though bottled water may not be the best water for a humidifier, it is a step up from tap water.

Should I use filtered water in my humidifier?

Using filtered water in a humidifier is better than using water straight out of the tap. But even filtered water is not 100% pure of minerals and other solids that can end up doing damage to your humidifier. 

And water filters are not able to get rid of all the fluoride and chlorine that is in tap water.

Though it is better than using tap water, filtered water still has much of the mineralization and propensity to develop mold and bacteria.

Should I boil the water I use in my humidifier?

 Boiling water is a do it yourself technique for humidifying your home without the use of a humidifier. When water is boiled it turns into steam and evaporates.

 Boiling water also kills any microorganisms in the water. 

But, the pot that you boil the water in is full of deposits and minerals left behind from the tap water.

If you pour the water directly out of the pot into the humidifier, much of the deposits that have been boiled out of the water will get back into the water.

The very thing you’re trying to avoid.

Much is made about how vaporizers and warm mist humidifiers are not as likely to develop mold and bacteria in them because the water is brought to a boiling point that kills the organisms. 

But you have to remember that minerals and deposits are left behind when you boil water.

Even in the case of vaporizers, distilled water is going to be the best water to use in your warm mist humidifier.

Caution:  And remember that the humidifier is made out of plastic. Pouring boiling water into it, is going to melt it. Let it cool first if you decide to do it this way.

Should I put hot or cold water in my humidifier?

Humidifiers do not need to have the water brought to any certain temperature before pouring it into the basin. 

 Normal room temperature is adequate. 

Some might get the idea of that because a vaporizer uses steam to humidify, that you have to put boiling water in it for it to work.

 Not so. The humidifier is built to warm the water on its own and does not require you to do anything besides fill it with room temperature distilled water. 

But by the same token, if you pour cold drinking water out of the refrigerator into a vaporizer, it’s going to take that much longer to work because it takes longer for cold water to get to a boiling point.

So just stick with room temperature.

And excessive cold or hot temperatures are not good for plastic and will eventually cause plastic to crack.

Recap

Distilled water is the best water to use in a humidifier because it goes through a process that eliminates the most minerals and microorganisms that can damage your humidifier and get into the air you breathe when you put them through a humidifier. 

It also is the best water to avoid the white dust that builds up around humidifiers.

 Bottle drinking water is a little better than using straight tap water in a humidifier but it’s still contains a great deal of the minerals that can cause a humidifier to scale up and be less effective.

And it is the minerals in the water that eventually become the white dust that you see settling around a humidifier.

 Boiled water does have the advantage of killing the spores and bacteria that can be in your average tap water, but when you boil water, the mineral deposit settle at the bottom. 

If you pour that water into a humidifier, you still have the problem of the mineral deposits getting into the humidifier.

Lastly, tap water is easily the worst water you can use in a humidifier. 

It is full of minerals and chemical treatments that will not only eventually damage your humidifier, will become part of the air you breathe when you use the water to humidify the air.

Tap water also becomes moldier faster and leaves the white dust that you were trying to avoid around your humidifier faster.

What are VOCs?

VOCs are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Examples include:

  • Paints and lacquers
  • Paint strippers
  • Cleaning supplies
  • Pesticides
  • Building materials and furnishings
  • Office equipment such as copiers and printers
  • Correction fluids and carbonless copy paper
  • Graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions
  • Hobbies
  • Dry-cleaned clothing
  • Air fresheners
  • Personal care products
  • Disinfectants

Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.

Best Air Purifier for VOCs and FormaldehydeHealth Effects of VOCs

Exposure to VOCs can cause both short-term and long-term health effects. General symptoms include:

  • Eye, nose, and throat irritation
  • Headaches
  • Loss of coordination
  • Nausea
  • Damage to liver, kidney, and central nervous system

Formaldehyde is classified as a human carcinogen and benzene exposure is associated with leukemia. Other health effects include:

  • Eye, nose, and throat irritation
  • Wheezing and allergic reactions
  • Fatigue
  • Skin rashes

Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans. The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effects. As with other pollutants, the extent and nature of the health effect will depend on many factors including level of exposure and length of time exposed.

What is Formaldehyde?

Formaldehyde is a colorless, strong-smelling gas commonly used in pressed-wood products, composite wood products, and furniture made with pressed wood products. It is also commonly used as an industrial fungicide, germicide, and disinfectant, and as a preservative in mortuaries and medical laboratories.

Formaldehyde is naturally occurring and can also be produced in small amounts by most living organisms as part of normal metabolic processes. However, elevated levels can cause adverse health effects.

  • Eye, nose, throat, and skin irritation
  • Wheezing and coughing
  • Asthma attacks
  • Fatigue
  • Skin rashes
  • Severe allergic reactions

Long-term exposure to high levels of formaldehyde is associated with an increased risk of cancer. The National Cancer Institute (NCI) determined that exposure to formaldehyde may cause leukemia, particularly myeloid leukemia, in humans.

What to Look for in an Air Purifier for VOCs and Formaldehyde

Here are the key features to look for when shopping for an air purifier optimized for removing VOCs and formaldehyde:

  • Activated Carbon Filter – The most critical component. Activated carbon adsorbs gaseous pollutants.
  • Large Carbon Filter Surface Area – The more carbon the better for catching VOCs and gases.
  • Sealed Edges – Prevents pollutants from bypassing the carbon filter.
  • Supplementary Filtration Technologies – PCO, PECO or other methods to destroy VOCs are beneficial.
  • Real-Time Pollution Sensor – Alerts you to spikes in VOCs and automatically adjusts fan speed.
  • App Connectivity – Allows monitoring air quality when away from home.
  • CADR Rating – A higher clean air delivery rate means faster air purification.
  • Noise Level – Units with large fans can generate significant white noise.
  • Coverage Area – Match the unit’s specs to the size of your rooms.

Also consider whether you want a portable unit or a whole-house system with multiple air purifiers working together.

Where to Place the Air Purifier

Strategic placement of your air purifier will improve its effectiveness. Some tips on where to put it:

  • Near known sources of VOCs and formaldehyde like pressed wood furniture or recently painted walls.
  • In rooms where you spend the most time such as bedrooms and family rooms.
  • Away from objects that may obstruct air flow.
  • Elevate the unit if possible to optimize air circulation.
  • Avoid corners and alcoves which can restrict air flow.

You may need more than one air purifier if your home is large, has an open floor plan, or VOC sources are located far apart. Let the unit run continuously instead of only when you are home.

FAQs

1. Do air purifiers remove all VOCs and formaldehyde?

The best air purifiers are highly effective at removing most VOCs and formaldehyde, but may be less effective on some types. No air purifier eliminates 100% of these pollutants. However, they significantly reduce concentrations to safer levels.

2. How long does it take an air purifier to remove VOCs and formaldehyde?

Air purifiers with large amounts of activated carbon and powerful fans can purge VOCs and formaldehyde within hours of operation. But it depends on VOC levels and other factors like room size. Run times of days or longer may be needed to thoroughly purify the air in some cases.

3. Is it worth buying an air purifier just for VOCs and formaldehyde?

If you are highly sensitive to VOCs/formaldehyde or know exposure levels are high, a specialized air purifier is worth the investment for your health. If exposure is moderate, a general HEPA air purifier with added carbon may suffice.

4. Can air purifiers help with “new home smell” from VOCs?

Yes, “new home smell” is caused by high levels of VOCs from new furniture, carpeting, paints, and building materials. An air purifier with substantial VOC removal abilities can help eliminate this smell faster.

5. Should I leave an air purifier running all the time?

It is generally recommended to run air purifiers continuously if trying to control VOCs, formaldehyde or other gaseous pollutants. This maintains lower concentrations consistently rather than allowing buildup when the unit is off.

6. How do I know if VOC or formaldehyde levels are too high in my home?

The most definitive way is to do professional air quality testing. But signs like persistent odors, eye/nose/throat irritation, breathing issues, and headaches may indicate a problem. Many air purifiers also have VOC sensors that display real-time readings.

7. Can air purifiers reduce the risk of cancer from formaldehyde?

The ability of air purifiers to reduce cancer risk is unclear. But by maintaining formaldehyde concentrations at or below recommended health guidelines, air purifiers likely help lower cancer risk.

The Bottom Line

VOCs and formaldehyde are two major indoor air pollutants that can accumulate to dangerous levels inside homes. Investing in an advanced air purifier with large amounts of activated carbon filtration and supplementary technologies will provide the best protection by removing these chemicals from the air you breathe.

Carefully research air purifier models, read reviews, and compare their VOC/formaldehyde removal capabilities before making a purchase. Strategically place the unit and run it continuously for optimal results. Improving indoor air quality promotes better health and can reduce irritation and symptoms caused by exposure to VOCs and formaldehyde inside the home.

AC Dehumidifier(Dry) Mode- What and When Do You Use It?

What is Dehumidifier (Dry) Mode in AC?

High Humidity is the number one cause of mildew and mold growth in the home.  It is also responsible for increased Allergy symptoms and can be a trigger for an Asthma attack.

Dehumidifier mode, also called Dry Mode,  on an AC is the setting that turns on the dehumidifying function of an air conditioner to reduce excess humidity in the air.

When there is too much humidity in the air, the temperature can seem hotter than what it actually is.
Using the dehumidifier/ dry mode on the AC will help reduce the moisture in the air and restore comfortability back to your home.

 

What is the function of dry mode in AC?

Dry mode in an AC functions like a dehumidifier. Dehumidifiers and air conditioners are actually very similar in the way they work. They both drag air across a set of cooling coils that causes the air to condense.

User Guidelines for AC Dehumidifier (Dry) Mode

Condition Dry Mode Usage Recommended Settings Notes
High Humidity, Mild Temperature Yes Moderate fan speed Ideal for reducing humidity without overcooling the room.
High Humidity, High Temperature Optional Combine with cool mode at a higher temperature setting Helps in maintaining comfort without excessive cooling.
Moderate Humidity, High Temperature No Use cool mode instead Dry mode is less effective and unnecessary.
Continuous High Humidity Yes, intermittently Use periodically to maintain comfort Prevents overuse and maintains energy efficiency.
Night Time or Low Activity Yes Lower fan speed, higher temperature Reduces noise and maintains comfort during less active hours.

AC Dehumidifier Dry ModeAir conditioner dry mode vs. dehumidifier

The difference is that air conditioners move the air across the cooling coils to cool off the air where is a dehumidifier moves the air across the cooling coils to condense the air but then reheats the air to repeat the process.

Dry mode vs. cool mode

Dry mode on your AC is the air conditioning setting that turns on the dehumidification function of the AC to reduce the humidity in the air.

Cool mode is the setting that cools down the air. Cool mode is the most common setting on an AC. It is the mood of the air conditioner that cools down the room to the temperature that you set the thermostat to.

Air conditioner dehumidifier mode

Humidity, especially the excessive humidity that tends to hit in the hottest months can be a real enemy to your air conditioning.

When the relative humidity gets to a certain level, you can feel like the air conditioner is not even on.

And usually what happens is that you run to turn the thermostat down cooler.

But with so much moisture in the air and adding more power to the air conditioner, the results of turning the air conditioner thermostat down usually leads to the unit freezing over.

Then there is no cool air coming from it at all.

Another reason that humidity threatens your AC unit is that your system has to run on overdrive to keep up with the extra demand that the humidity places on it.

But you may be sitting on an air conditioner that has a function to help in those situations. And you might not have even known it.

The function I’m talking about is the air conditioner dehumidifier mode.

The air conditioner dehumidifier mode is usually represented by a raindrop symbol on the thermostat. It is also called the dry mode if you have an air conditioner with this function but it does not say dehumidifier.

what is dry mode in ac

Does an air conditioner dehumidify?

When your AC is in dehumidifier mode,
It turns off the cooling function and slows down the fan so that the air conditioning functions as a dehumidifier to reduce the moisture in the air.

Does air conditioning dry out the air?

By reducing the moisture in the air, you can regain comfortability without even having the cool mode running.

Not only will that save you money on energy, it will help save you in the long run by not overworking your air conditioning system.

Best temperature for dry mode

The best temperature to use dry mode is when the humidity is excessive but the actual temperature is not that hot.

The ideal of turning the AC on dry mode is to reduce the moisture level in the air and restore the comfortability of the area without using the cool air mode of the AC.

The function of Dry mode on an AC is to lower the humidity in the room so that the air feels cooler. It does not actually control or utilize the thermostat to achieve a designated temperature.

Dry mode vs. Cool mode power consumption

ACs are one of the biggest energy hogs in your house. Everyone knows how much the utility bill can skyrocket in the summer months because of the power that an air conditioning system uses.

The different modes on an air conditioning unit or not only to help provide you with the most comfort possible in terms of climate control but also in financial terms.

The cool mode on an air conditioner is easily the most expensive to run. And it is the setting that most people tend to use exclusively.

But there are different times when using the cool mode on an air conditioner is not only more expensive, it can’t get the job done as well.

Dry mode on an air conditioner can actually lower your energy bill provided the climate dictates it.

When the humidity is so high that it is overcoming the air conditioning,

Turning the AC dry mode will not only help reduce the humidity in the air and make the air feel more comfortable, it will turn off certain features on the air conditioner that are causing the energy bill to be more expensive.

When the dry mode is functioning, it turns down the cool air and it slows the fan way down.

Which means the power consumption of the air conditioner is way down.

In other words, less power, more money in your pocket.

Not only does humidity cause your air conditioner I do feel like it’s doing less than an adequate job, it also makes your air conditioner overcompensate to try to get the temperature in the room down to a comfortable level.

That means the power consumption in cool mode during times of excessive humidity will actually cost you more.

Air conditioner dry mode in winter.

The dry mode on an air conditioner, though it works like a dehumidifier to a certain point.
But at the end of the day they do not have the full function of a dehumidifier.

A dehumidifier compared to a air conditioner not only condenses the water to capture the humidity, it reheats the air that is released.

An air conditioner simply does not have this capacity.

Even most dehumidifiers call for the temperature to be at least 60 degrees.
Which makes them obsolete during the winter.

Using an air conditioning as a dehumidifier during the winter will not work for that intention, it will most likely cause damage to your unit.air conditioner dehumidifier mode

Limitations and Considerations

While the dry mode in AC units can mitigate humidity to some extent, it may not match the efficacy of specialized devices like standalone dehumidifiers.

Considering such a product could enhance moisture management, especially in highly humid environments, providing a more comprehensive solution than AC dry mode alone.

Why Central Heating Causes Dry Coughs and How to Prevent Them

Why is My Central Heat Making Me Cough?

If you find yourself coughing more often when the central heating is on, you’re not alone. Central heating can dry out the air and irritate respiratory passages, leading to coughing for some people. However, it’s not just the dry air that could be causing discomfort. Mold in HVAC systems can also contribute to respiratory issues, including coughing. Thankfully, there are steps you can take to mitigate these effects and keep your airways calm.

Why Central Heating Causes Dry Air

Central heating works by warming air and distributing it throughout your home via vents and ducts. However, this heated air lacks moisture. As it circulates, the dry air evaporates moisture from surfaces like your skin, nasal passages, throat, and lungs, which can make tissues dry, irritated, and inflamed, triggering coughing.

Colder outdoor air holds less moisture than warm indoor air. So when you heat up cold outdoor air, its relative humidity drops dramatically. Central heating systems also lack a humidification component to add moisture back into the air.

dirty ductThe Hidden Hazards of Dirty Ducts

 Dirty ducts can significantly compromise your indoor air quality and the efficiency of your HVAC system.
Accumulated dust, pollen, pet dander, and other pollutants in the ducts can circulate contaminated air throughout your home, exacerbating allergies, respiratory problems, and asthma symptoms. Moreover, this buildup can restrict airflow, forcing your system to work harder and leading to increased energy consumption and decreased system efficiency.2

Recognizing the signs of dirty ducts is key to maintaining a healthy indoor environment.
Indicators such as visible dust buildup around vents, unusual odors when the HVAC system is running, and an increase in respiratory issues or allergic reactions can signal the need for professional duct cleaning. Ensuring your ductwork is clean not only enhances air quality but also contributes to the overall efficiency and longevity of your HVAC system.1

Ventilation and Air Circulation

Before we delve into advanced air purification technologies like UV light solutions, it’s essential to understand the foundational role of ventilation and air circulation in maintaining indoor air quality. Proper ventilation is key to ensuring a healthy living environment, especially during the heating season when homes are sealed tight against the cold.

Why Ventilation Matters

Ventilation involves the exchange of indoor air with fresh outdoor air, which helps to reduce the accumulation of indoor air pollutants, including dust, allergens, and volatile organic compounds (VOCs). Good ventilation practices can also help mitigate the drying effect of central heating by introducing air with a higher moisture content from outside, particularly in areas with relatively humid outdoor climates.

Strategies for Improved Air Circulation

  • Natural Ventilation: Simply opening windows and doors for short periods can significantly improve air quality, even in cold weather. This allows stale, dry air to escape and fresh, moist air to enter.
  • Mechanical Ventilation: For homes in extreme climates or those with poor natural ventilation, mechanical systems such as Heat Recovery Ventilators (HRVs) or Energy Recovery Ventilators (ERVs) can provide controlled ventilation without significant heat loss.
  • Ceiling and Exhaust Fans: Utilizing ceiling fans can help circulate heated air more evenly throughout your home, reducing hot and cold spots and improving comfort. Exhaust fans, especially in kitchens and bathrooms, are crucial for removing excess moisture and odors and preventing mold growth.

The Role of Air Circulation

In addition to bringing in fresh air, ensuring that the air inside your home moves effectively can prevent the accumulation of airborne pollutants. Air circulation can be enhanced with strategic use of fans, ensuring that air filters are clean and unobstructed, and making sure that furniture does not block air vents.

hvac coughMold in HVAC Systems

In addition to drying out the air, central heating systems can harbor mold, which exacerbates respiratory issues. Mold thrives in moist environments, and when it grows in the ductwork or on other HVAC components, spores can spread throughout your home. Inhaling these spores can cause allergic reactions, exacerbate asthma, and provoke coughing.

Regular HVAC maintenance is crucial to prevent mold growth. This includes cleaning or replacing air filters, ensuring proper drainage, and inspecting ductwork for signs of moisture or mold. If mold is detected, professional cleaning may be necessary to remove it and prevent future growth.

Can I Put a Window Air Conditioner Work on the Floor? Why Not?

Will a window air conditioner work on the floor?

Technically, a window air conditioner can turn on and run while sitting on the floor. However, the way a window AC unit expels heat, drains condensation, and exchanges air can make using it on the floor less than ideal. These units are designed to be mounted in a window or through a wall to ensure proper ventilation, efficient cooling, and effective moisture drainage. Placing a window AC on the floor may lead to reduced efficiency, potential damage to the unit, and inadequate cooling performance.

Introduction

It’s not uncommon to find yourself in need of an air conditioner while being confined to an area where installing one isn’t exactly straightforward.

Various circumstances might lead you to occupy a room without windows, or perhaps you’re in a garage, workshop, or another type of space not originally designed to accommodate a window air conditioner.
In such situations, it’s tempting to consider using a spare window air conditioning unit you might have on hand. The question arises: Can this device simply be brought inside and placed on the floor or a table to cool the room?

Unfortunately, the design of window air conditioners doesn’t support effective cooling when the unit is not properly installed in a window.

These devices are specifically engineered to operate within a window frame, ensuring optimal air exchange, efficient cooling, and proper moisture drainage.

When placed in an unintended location, such as on the floor, their performance is significantly compromised, leading to inefficiency and potentially even damage to the unit.

In this article, we aim to elucidate the critical role of placement in maximizing the effectiveness of a window air conditioner. The concept of placing such a unit on the floor serves as an illustrative example to highlight how positioning impacts its functionality.

How does the placement of a window air conditioner effects how it will cool a room.

Heat Expulsion

Window air conditioners are designed to expel heat from their rear. If you’ve ever passed behind one, you’ve likely felt the warm air being emitted. Placing a window AC on the floor would result in it discharging cool air from the front but simultaneously releasing hot air from the back, effectively negating the cooling effect. The design intention behind these units is for them to be mounted in a window, allowing them to expel heat outside, not into the room.

Drainage

These units also work by extracting moisture from the air, condensing it, and then draining it through a hole at the bottom. This design is another reason why window ACs are intended for window installation, ensuring that the condensation exits the unit outside the house, preventing indoor water accumulation.

Hot Air Circulation

Considering that hot air rises and the coolest air in a room is near the floor, a window AC placed too low may recycle this cool air instead of drawing in and cooling the warmer air above. This could result in inefficient cooling, especially in the areas of the room where it’s most needed.

Noise Levels

The design of a window air conditioner also takes into account noise reduction, with the noisier components like the compressor and motor positioned to be outside the house when installed in a window. Placing the unit indoors would lead to increased noise levels, making the environment less comfortable.

Emergency Use

In emergency situations where no other cooling options are available, a window AC can technically be run on the floor. Direct exposure to the cool air can provide relief, albeit in a limited area. However, it’s important to manage the drainage by placing a pan underneath to collect water, and be prepared for increased indoor noise and potentially uneven cooling.

Ultimately, while a window air conditioner can function on the floor in specific scenarios, such placement is far from ideal and undermines the unit’s efficiency, design purpose, and overall effectiveness in cooling a room.

Can you put a window air conditioner on a table?

Placing a window air conditioner on a table does offer a slight improvement over having it on the floor, primarily because it would be positioned to draw in warmer air from the room rather than the cooler air found at floor level.

Even when elevated on a table, the air conditioner would still expel hot air from its rear. This expelled heat could warm other areas of the room, counteracting the cooling effect generated at the front of the unit. In a typical window installation, this heat is directed outside, away from the interior space.

Also the problem of condensation drainage persists. Window air conditioners are designed to allow condensation to drip outside when mounted in a window. When placed on a table, there would need to be an alternative method to collect or direct this water away, preventing damage to the table surface and avoiding water accumulation on the floor.

The operating noise, particularly from the compressor and motor, would be more pronounced when the unit is used inside the room instead of being partially outside a window.

DIY Engineering Solutions

Some people have creatively addressed these challenges by employing DIY methods, such as attaching ductwork to the rear of the unit to channel the expelled heat into an attic, closet, or another area where it won’t raise the room’s temperature. While this can be an effective workaround for the heat expulsion issue, it requires a certain level of technical skill and understanding of air conditioning systems to implement safely and effectively.

Considerations

If you’re in a situation without window access but have a window AC unit, exploring such DIY solutions might seem appealing. However, it’s crucial to address the drainage issue by finding a way to capture or direct the condensation effectively. Additionally, the increased noise level from having the unit operate entirely indoors is an important factor to consider for your comfort and the comfort of others in the space.

How Do You Cool a Room with No Windows?

Method Description Best For
Portable Air Conditioners Versatile units that require venting through ceiling, dryer vent, or wall. Need drainage for condensation. Flexible cooling, temporary setups
Evaporative Coolers Best for dry climates, use water evaporation to cool air. Add moisture, no external venting needed. Dry, low-humidity areas
Split Ductless Air Conditioners Consist of outdoor and indoor units, require professional installation. Quiet and efficient. Permanent, efficient cooling solution
Fans and Air Circulation Improve air movement without lowering temperature. Makes the room feel cooler by circulating air. Immediate airflow improvement
Thermal Curtains and Insulation Prevent heat from entering by using insulating materials on doors or adding wall insulation. Reducing heat gain from outside
Dehumidifiers Remove moisture from the air, making the room feel cooler in humid climates. Humid climates
Cool Roofing or Reflective Materials Use materials that reflect sunlight to reduce heat absorption in rooms at the top of buildings. Top-floor or attic rooms
Heat-Generating Appliance Management Reduce use of appliances that generate heat, especially during hot parts of the day. All areas, especially small, enclosed spaces
Creative Venting Solutions Use vents to circulate cool air from adjacent rooms or expel warm air to the outside. Rooms adjacent to cooled or ventilated spaces

Cooling a room without windows presents a unique challenge, as traditional window air conditioners are not an option. However, there are several alternative methods to cool such a space effectively:

1. Portable Air Conditioners

Portable air conditioners are a versatile solution. They don’t require window access for installation but do need a way to vent hot air outside. This can be achieved through a drop ceiling, dryer vent, or a hole in the wall. Ensure the unit has an appropriate drainage system for condensation.

2. Evaporative Coolers (Swamp Coolers)

Evaporative coolers are best suited for dry climates. They use the evaporation of water to cool the air, which can be an efficient method in areas with low humidity. No external venting is required, but they do add moisture to the air, which might be a consideration depending on the climate.

3. Split Ductless Air Conditioners (Mini-Split Systems)

Mini-split systems are an efficient way to cool rooms without windows. They consist of an outdoor compressor/condenser unit and one or more indoor air handling units, connected by a small conduit. Installation requires a professional but offers a permanent, quiet, and efficient cooling solution.

4. Fans and Air Circulation

Enhancing air circulation can also help cool a room. Ceiling fans or oscillating fans don’t lower the room temperature but can make it feel cooler by moving air around. Strategically placed fans can help circulate cool air from other parts of the building into the windowless room.

5. Thermal Curtains and Insulation

Improving the room’s insulation can prevent heat from entering. Using thermal curtains or blackout curtains on any doors leading to brighter, hotter areas can help keep the room cooler. Insulating any ductwork or adding insulation to walls can also reduce heat gain.

6. Dehumidifiers

In humid climates, a dehumidifier can make a room feel cooler by removing moisture from the air, even though it doesn’t lower the temperature. Less humidity means sweat evaporates more quickly, which naturally cools the body.

7. Cool Roofing or Reflective Materials

If the room is at the top of a building, using cool roofing materials or reflective paint can reduce heat absorption from the sun, keeping the space cooler.

8. Heat-Generating Appliance Management

Minimize the use of heat-generating appliances within the room during the hottest parts of the day. This includes computers, printers, and especially kitchen appliances if the space includes a cooking area.

9. Creative Venting Solutions

If there’s access to an adjacent room with windows or external walls, you can create a venting solution through the adjoining wall to help circulate cool air into the windowless space or expel warm air.

When choosing a cooling method, consider the room’s size, your budget, and the climate in your area. Some solutions may require professional installation, but they can provide a comfortable and sustainable environment in windowless rooms.

 

Do You Have to Use Distilled Water in a Humidifier? Really?

Do You Have to Use Distilled Water in a Humidifier?

“No. A humidifier will work with any type of water, distilled, tap, or otherwise, to add moisture back into the air. It’s a fact. But certain types of water, especially tap water,  because of the mineral and chemical content, will shorten the life of your humidifier and lower its output.

Introduction:

What is the problem with not using distilled water in a humidifier? The truth is you can get away with using tap water in a humidifier or a CPAP machine for a while. But eventually the mineral content will become a problem for your humidifier or CPAP machine.

This is true story:

Recently my wife had an issue with her CPAP machine. if you’re not familiar with what a CPAP machine is, it’s a device that helps you breathe while you sleep. It comes with a mask that you put on, that basically pushes oxygen into your lungs.

And just like a humidifier they are required to be filled with water.

As the story goes, this specific CPAP machine that my wife was using stopped working.

With some aggravation, She immediately she got a hold of the manufacturer who agreed that they would send a shipping label for her to send it in to get it fixed.

And just like they promised, the whole transaction went smoothly and they repaired the device and send it right back.

The invoice that was included in the package specified the problem:

“unit was clogged up, thoroughly cleaned and working properly again. Solution, switch to distilled water”

A lot of hassle and money to get a CPAP machine repaired to find out that she was using tap water to fill it, and the minerals in the water had eventually stopped up the machine where it would not function.

So do you have to use distilled water in a humidifier? No it will work with tap water, But eventually you may wish you would have.

Water Types for Humidifiers

Water Type Mineral Content Potential Impact on Humidifier Suitability for Humidifiers Maintenance Tips
Distilled Water Very Low Minimal scaling and buildup Highly Recommended Regular cleaning with less effort
Tap Water High Increased scaling, potential for clogging Not Recommended Frequent deep cleaning required
Bottled Water Variable Possible scaling depending on mineral content Better than tap, worse than distilled Regular cleaning recommended
Boiled Water Reduced Less scaling than tap water, but some minerals remain Better than tap, not as ideal as distilled Regular cleaning with attention to mineral buildup

Distilled Water For Humidifiers? Why is it Best?

Distilled water is the best water to use in a humidifier because of its low mineral content. Because of the process it goes through, it has the lowest mineral content of any type of water.

This is important for a few reasons:

1.The mineral content in most drinking water will eventually shorten the life of your humidifier and lower the output by stopping it up.

2. The minerals in most water are what is responsible for the dust that you see gathering around your humidifier.

Since dust is one of the primary reasons that your skin gets dried out in dry weather, using water with a lot of mineral content in a humidifier can produce the opposite effect than intended.

3. The higher the mineral content in the water that you use in a humidifier, the more likely, the growth of mold and bacteria in the water.

Can you use regular tap water in a humidifier

Can I Use Regular Water in a Humidifier?

Is it dangerous to use regular tap water in a humidifier. No.

Now more so than drinking tap water.

And though most of us probably drink bottled water more regularly than tap water, anytime you purchase tea or coffee from a restaurant, it’s going to be made with tap water.

So whether we believe that tap water is good to drink or not, most of us are most likely consuming it on a regular basis.

The issue with tap water being used in a humidifier are primarily about the high mineral content in tap water.

The higher the mineral content in the water that you use in a humidifier, the more likely to get stopped up and not work properly.

And it’s the mineral content in the water that creates the white dust that accumulates on the humidifier and around it.

Since dry skin is one of the primary reasons people purchase humidifiers and dust is one of the primary things that pulls the moisture out of your skin,
operating a humidifier that is creating more dust by using tap water somewhat counterproductive.

Another issue with tap water is that the minerals in the water have more of a chance to become food for mold to be able to take root inside of a humidifier.

Finally, tap water has a whole list of chemicals that are there “for our own good apparently” that you do not necessarily want to breathe in as part of the moisture content in your air.

Tell me again why they put “fluoride” in tap water?

So even though tap water is definitely not the best option for a humidifier, the issues with it are not immediately harmful or dangerous. And if that’s all you have at your disposal, you know the risk,

And it’s not like you can’t clean your humidifier extra well after you use tap water in it. And as for the dust, keep it wiped up.

bottled water for humidifierWhat other water besides distilled can you use in a humidifier?

Bottled?

Bottled water has a lot of minerals in it that could be an eventual problem for your humidifier. Even the water that is produced by using reverse osmosis has the disclaimer on it that minerals are added back to make it more consumable.

It’s a better option than tap water but it still has its fall backs.

Boiled water?

Boiling water causes the minerals in the water to settle. So if you had a way to separate the settlement so that it did not make it into the humidifier with the rest of the water, it would make a great choice.
The problem is, making that happen. Not exactly easy to do.

 

warning-dirty humidifier water ahead

But there is absolutely one type of water you should never run your humidifier with.

Stagnant water

Water that has been allowed to sit inside of your humidifier is going to be moldy and full of germs and bacteria.

And when you turn that humidifier on with that stagnant water still in it, the germs and bacteria in that water will become part of the air that you are breathing.

Now talk about having the opposite effect than you intended, the humidifier that was supposed to make you feel better, has basically become a weapon of germ warfare.

Legionnaires’ disease and humidifier lung are harsh reminders of what can happen when humidifiers and evaporative coolers are allowed to sit with moldy water.
You can easily look up the symptoms of mold allergies and discover that they look very closely like the symptoms of the flu.

So if you think that the humidifier in your house may be making you sick, you may be right. And you should take it seriously.

Fortunately, Humidifiers have become pretty sophisticated devices and many of them have ways of helping control mold growth.

If you’re in the market for a new humidifier, it’s well worth it to look into some of the features that can help reduce the chance mold and bacteria growing in your humidifier and becoming part of the air you’re breathing.

There are additives that you can place in your humidifier that can reduce the chances of a humidifier developing bacteria too.

Maintenance Tips for Humidifiers

Proper maintenance is crucial for ensuring your humidifier operates efficiently and safely, extending its lifespan and improving indoor air quality. Regardless of the water type you choose, here are some essential maintenance tips to keep your humidifier in top condition:

  • Regular Cleaning: Clean your humidifier regularly to prevent the buildup of minerals and the growth of mold and bacteria. Depending on usage, a thorough cleaning every 1-2 weeks is recommended.
    • Empty the water tank, dismantle the parts, and clean them with mild soap and warm water.
    • Use a soft-bristled brush to scrub away any mineral deposits or buildup.
  • Use Distilled Water When Possible: While not always necessary, using distilled water can significantly reduce mineral buildup and the need for frequent descaling, making regular maintenance easier.
  • Descale and Disinfect: Even with distilled water, it’s important to descale and disinfect your humidifier to remove any mineral deposits and kill germs that could be harmful.
    • Descale the humidifier by using a mixture of white vinegar and water. Let it sit for at least 30 minutes, then rinse thoroughly.
    • Disinfect the water tank and other parts by using a diluted bleach solution (1 teaspoon of bleach per gallon of water) or hydrogen peroxide. Rinse all parts thoroughly after disinfection to ensure no chemicals remain.
  • Change Filters Regularly: If your humidifier has a filter, follow the manufacturer’s recommendations for changing it. Filters can harbor mold and bacteria, reducing air quality and humidifier efficiency.
  • Dry Before Storing: If you plan to store the humidifier for an extended period, ensure it is completely dry to prevent mold and bacteria growth. Disassemble the parts, clean them thoroughly, and let them air dry before storing.
  • Monitor Humidity Levels: Use a hygrometer to monitor room humidity levels, maintaining them within a comfortable range of 30-50%. This helps prevent problems associated with over-humidification, such as mold growth and condensation on windows.
  • Check for Leaks and Damages: Regularly inspect your humidifier for any signs of leaks or damage. Addressing these issues promptly can prevent further damage and potential water damage to your surroundings.

Pros and Cons of Using Distilled Water in Humidifiers

Pros Cons
Minimizes Mineral Deposit Buildup: Cost:
Using distilled water reduces the accumulation of mineral deposits inside the humidifier, thereby extending its lifespan and maintaining its efficiency. Regularly purchasing distilled water can be more expensive than using tap water.
Less Maintenance Required: Accessibility:
Due to fewer mineral deposits, humidifiers operating with distilled water require less frequent cleaning and maintenance. Distilled water may not be as readily available as tap water, requiring extra trips to the store or the need to distill water at home.
Reduces White Dust Formation: Environmental Impact:
The low mineral content of distilled water minimizes the white dust that often accumulates around humidifiers using tap or hard water, leading to cleaner air and surfaces. Buying distilled water in plastic bottles can increase plastic waste, contributing to environmental concerns.
Prevents Microbial Growth: Not Always Necessary:
Distilled water is less likely to harbor bacteria and mold because it lacks the minerals and impurities that feed microbial growth in humidifier tanks. For some humidifiers, especially those with built-in filters or demineralization cartridges, the benefits of using distilled water might be less significant.

Summary


Do you have to put distilled water in a humidifier?

No. Even though distilled water is the best water to keep your machine from stopping up and extending the life of your humidifier,
A humidifier will work without it.

And though everyone agrees that tap water is the worst water you want to use in a humidifier, you can use it without having to worry about it being dangerous to you.

The main issue with tap water is that it is filled with minerals that can stop up your humidifier. And those minerals can and will produce humidifier dust on your unit and around it.

If tap water is what you have available, then do your best to keep your humidifier clean with vinegar and keep the dust around the humidifier wiped up so it does not become part of the air quality.

Arguably, The most important thing to remember when using a humidifier is to never run it with stagnant moldy water in it.

Mold in your air can produce very similar symptoms to the flu. Pneumonia, humidifier lung, and legionnaires are harsh reminders of what can happen when mold is allowed to grow in water unchecked.

Is 60 humidity Too High in a House? What About 70? 80?

60 humidity Inside the House? Is that Considered Too High?

Yes, an indoor humidity level of 60% is generally considered too high for most homes.
High indoor humidity can also lead to health issues by encouraging the growth of mold, mildew, and dust mites, which are common allergens and irritants. Furthermore, excessive moisture can damage your home’s structure and furnishings by causing wood to warp, paint to peel, and unpleasant musty odors to develop.

Humidity has a big effect on your health and property, and the truth is, it is much more serious than you probably ever gave it credit for. Both high and low humidity comes with its own problems and symptoms.

This article is about many of the symptoms and problems that you can expect with high humidity. And some solutions too.

40 to 60% relative humidity is the optimal range to protect your home and family from the spread of germs and avoid damage to your personal property.

A direct statement by ncbi.nlm.nih.gov
says “health effects caused by road of humidity would be minimized by maintaining indoor levels between 40 and 60%”

Humidity Level Symptoms
60% Nearing discomfort range, potential for mold growth, increased allergens like dust mites.
70% AC inefficiency, visible condensation, clammy skin, frizzy hair, sneezing, itchy eyes, increased mold and mildew growth.
80% Wheezing due to dust mites and mold spores, risk of dehydration, reduced physical performance, wood rot, damage to musical instruments, proliferation of fungi and bacteria.

Humidity 60 in the House

At 60%, the humidity in the house is nearing the outside of the range of what is considered comfortable and safe humidity inside of the home.

At 60% RH, you have already begun to enter into an area of relative humidity that can provide enough moisture in the air for mold to take root.

As that number increases, the likelihood of mold being found somewhere in your home increases.

The risk of mold growth increases significantly as humidity levels rise above 60%. And with mold comes mold spores. A significant household allergen.

70 humidity in house

At 70%, you are already noticing the telltale signs all around you.

The AC will begin to feel like it’s not running at all and condensation will be nearly pouring from it.

You will undoubtedly feel very clammy and will have no chance of dealing with your frizzy hair.

You might also find yourself sneezing and rubbing your itchy eyes.

Why is that?

It’s because dust mites thrive in temperatures that hover around the 70 to 80° range with a relative humidity of 70 to 80%.

In addition to the discomfort and presence of dust mites, high humidity levels like 70% can lead to other significant issues within your home.

The excessive moisture creates an ideal environment for the growth of mold and mildew, which can cause damage to your home’s structure and furnishings.

More importantly, mold and mildew release spores into the air, contributing to indoor air pollution and potentially leading to health problems such as respiratory issues, allergies, and asthma in susceptible individuals.

80 humidity in house

At 80% humidity, you may start wheezing because of the amount of dust mites and mold spores in the air.

And the risk of dehydration will become a real threat because your body will not be able to produce sweat nearly as easily at that level.

Your performance will be off and you will find that you’re not able to do as much without getting tired.

Humidity sustained at that level will begin to rot the wood around your home including window sills and floorboards.

And any musical instruments you have around the house will have probably gone way out of tune by now. And the risk of them bowing to a point that they may never play well again is serious.

Moreover, the pervasive dampness associated with 80% indoor humidity can lead to a proliferation of other allergens, such as fungi and bacteria, further compromising indoor air quality.

This environment not only exacerbates existing respiratory conditions but can also trigger new health issues among the home’s inhabitants.

Electronic devices and appliances are not immune to the ravages of high humidity either; the excessive moisture can corrode circuits and internal components, leading to malfunctions and a shortened lifespan for these items.

Uhh!!

As you can tell, a sustained high level of humidity is not good for your health or your home. If any of this describes your situation then you should be taking steps to remedy the situation.

Determine the Origin of the Humidity

Climate

Of course there’s not too much you can do about the weather. And if the outside humidity is shooting up then you’re inside humidity is going to shoot up with it.

Here’s a Few Solutions:

Air Conditioning

Refrigerated air conditioners, either the type you have built into your house via the HVAC or window air conditioners which would include portable air conditioners that vent out of the window, will reduce the humidity inside of the house.

This type of air conditioner pulls humidity out of the air, reduces it to condensation, and either drips or funnels it outside.

And most refrigerated ACs you find these days have a dehumidifier setting that will reduce the humidity in the room without having to have the cool function running. The dehumidifier setting on an AC is usually called “dry mode”. It’s symbolized by a water drop, if your unit has symbols instead of words.

Dehumidifier

The dehumidifier is a device that is similar to a refrigerator air conditioner except that it doesn’t have any type of cool setting.

It’s only function is to reduce the humidity.

Humidifiers exhaust heat similar to the way a window air conditioner does.If you have ever walked behind a window air conditioner then you probably remember feeling heat coming off of the unit.

But the heat that is exhausted on a dehumidifier is expelled inside of the room.

A factor you’ll want to consider when you’re thinking about operating a dehumidifier. Depending on the reason for the humidity, the heat exhausting from the machine it’s not exactly a welcomed feature if the temperature is already hot outside.

70 humidity in house

When is the AC not useful in humidity?

Even though refrigerator air conditioning is the easiest and most effective way to bring them the humidity level indoors, there are times when air conditioning will do the opposite.

AC humidity problems

1.  Running the AC with “fan on” setting engaged.

There’s a lot of confusion when it comes to running the air conditioner with the “fan on” setting engaged versus the “auto on” setting engaged.

The “fan on” setting well actually makes your home feel more humid.

The reason is, one of the primary ways that an air conditioner cools down a room is by extracting the humidity and turning it into condensation.

But when the “fan on” setting is engaged, the humid air that is being pulled into the air conditioner does not have a chance to stay in front of the condenser coils of the AC long enough to turn into condensation.

So the result is humid air being pulled into your air conditioner and redistributed throughout the house without the humidity being extracted.

2.  Too Large of an Air Conditioner

Another problem that can occur with air conditioning and humidity is that you have too large of an AC unit.

The result of running an AC unit that is too large for a home is a phenomenon called “short cycling”.

Which means that your air conditioner turns on and off more frequently.

This affects the way a air conditioner extracts humidity because the air conditioner is continually turning on and off,

and not giving the condenser coils enough time to turn the humidity into condensation and funneled out of the house.

humidity in house3.  Evaporative cooling

Evaporative coolers are essentially a large fan blowing over water as a means of cooling the air off.

Evaporative coolers are also known as swamp coolers because they can make a room feel swampy.

Number one, if you were trying to use a evaporative cooler when the humidity is high, you will not be able to feel anything much more than a fan coming from the unit at that point.

Number two, you are only adding more humidity to an already elevated moisture level.

And for some people this may be the reason your home feels humid in the first place.

Any devices or machines like evaporative coolers or humidifiers that disburse water droplets into the air, should not be operated when the humidity level is high in the house.

Leaking pipes

If you have above average humidity in your home but the climate outside is not especially humid, then you have another problem altogether.

Basements are usually known to be extra humid because of being located beneath the ground.

The moisture in the ground can find itself inside of your home.

Dehumidifiers can be outfitted with pumps and drainage hoses to reduce the humidity inside of a basement.

Leaking water pipes are also found in the basement quite often and can cause the humidity level to soar.

Telltale sons of leaking pipes inside of your home usually appear as drywall that is bowing or that feels damp to the touch.

Discoloration of the walls usually indicates a leak of some sort also.

Leaks in the ceiling are usually very easy to locate and are very noticeable because they appear as some liquid that has been spilled on the ceiling.

If the high humidity inside of the home is due to leaking pipes, then as you probably guessed, you’re going to need a plumber.

 

 

Is Breathing in Bleach Bad? What to Do If You Inhale Bleach Fumes

Is Breathing in Bleach Bad?

Yes, inhaling bleach fumes is detrimental as it exposes the respiratory system to sodium hypochlorite and chlorine gases, which can damage lung tissue and airways, leading to respiratory complications and chemical burns.

It can cause irritation to the eyes, skin, and respiratory tract, leading to symptoms like coughing, chest tightness, and in severe cases, respiratory distress.

Introduction.

Many of us know someone with a heightened sensitivity to strong odors, particularly the pungent smell of bleach. In my own home, that person is my wife.

The mere presence of bleach-based products in our cleaning routine is enough to trigger an immediate and unpleasant reaction for her. Even a task as mundane as cleaning the toilet with bleach is off-limits; it results in an instant headache and a wave of nausea for her.

This personal experience has led me to delve deeper into the effects of bleach exposure, emphasizing the importance of understanding and mitigating its impact, especially for those with heightened sensitivity.

Why Breathing Bleach is So Dangerous?

Bleach contains chemicals like sodium hypochlorite, hydrochloric acid, and sodium hydroxide. When bleach is mixed with water or acids, it releases chlorine gas. Chlorine gas can cause severe irritation and damage to the eyes, skin, lungs, and throat.

Inhaling chlorine gas can lead to coughing, wheezing, shortness of breath, chest pain, and fluid buildup in the lungs. At high concentrations, it can cause respiratory failure, pulmonary edema, and death.1

Effects of Breathing Bleach Fumes

Short-Term Effects Long-Term Effects
Coughing, choking Asthma
Throat irritation Respiratory infections
Burning eyes, nose, throat Lung scarring
Wheezing, chest tightness Chronic bronchitis
Nausea, vomiting Lung cancer

Exposure can irritate the eyes, skin, and respiratory tract. Short-term effects include coughing, choking, wheezing, nausea, and burning sensations. Long-term effects like respiratory infections, asthma, lung scarring, and even cancer can occur with repeated exposure.

Situations Where Bleach Inhalation Occurs

There are certain situations where bleach inhalation is more likely to occur:

  • Cleaning with bleach – Using bleach cleaners in small, poorly ventilated areas can allow concentrated fumes to build up.
  • Mixing bleach and other chemicals – Never mix bleach with products containing ammonia or acids, as this creates toxic chlorine and chloramine gases.
  • Accidents with bleach – Spilling bleach directly onto the skin or eyes can cause immediate burning and irritation.
  • Suicide attempts – Some use bleach to attempt self-harm through ingestion or inhalation. This is extremely dangerous.

inhale bleachWhat to Do When You Inhale Bleach

If bleach fumes are inhaled, it’s important to get to fresh air immediately. Other steps include:

  • Move the person away from the contaminated area.
  • Call emergency services like 911 immediately.
  • Administer oxygen if available.
  • Have them rest and avoid exertion.
  • Remove any contaminated clothing.
  • Flush eyes or skin with cool water if irritated.
  • Seek medical evaluation, even if symptoms resolve, as lung damage may have occurred.

Bleach inhalation requires rapid medical treatment to avoid complications. Never assume someone is fine just because initial symptoms like coughing have improved.2

How To Get Rid of Bleach Fumes

To reduce or eliminate bleach fumes in an area, follow these steps:

  • Ventilation: Open windows and doors to allow fresh air to circulate and disperse the fumes.
  • Air Purifiers: Use air purifiers with activated carbon filters which can help absorb chemical smells and fumes.
  • Neutralizing the Odor: Bowls of white vinegar or baking soda placed around the space can help absorb and neutralize odors.
  • Water and Lemon: Simmering a pot of water with sliced lemon can also help to purify the air and neutralize the bleach smell.
  • Fans and HVAC: Use fans to push air out and turn on the HVAC system to help filter the air.

How Long Do Bleach Fumes Last?

The persistence of bleach fumes can vary based on factors like the amount of bleach used, ventilation, and humidity levels. In well-ventilated areas, the fumes may dissipate within a few hours.

In poorly ventilated or more enclosed spaces, the fumes can linger for several days. Using air purifiers and increasing ventilation can speed up the process of removing fumes.

bleach headacheHow To Get Rid of a Bleach Headache

If you’re experiencing a headache from bleach fumes, consider these steps:

  • Fresh Air: Immediately move to an area with fresh air to reduce further inhalation of fumes.
  • Hydration: Drink plenty of water to help flush out any chemicals and to stay hydrated.
  • Rest: Rest in a well-ventilated room, away from the contaminated area.
  • Pain Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help alleviate headache symptoms.
  • Medical Attention: If the headache persists or is severe, seek medical attention as it could indicate a more serious exposure.

 

FAQ

Does Inhaling bleach Make You Cough?

Yes, inhaling bleach can definitely make you cough. The irritation caused by the chemicals in bleach, such as chlorine gas, can lead to a reflex cough. The body tries to expel the irritating substance from the respiratory tract, leading to coughing, throat irritation, and potentially other respiratory symptoms.

Is it safe to mix bleach and vinegar?

No, never mix bleach and vinegar. Mixing bleach and vinegar creates chlorine gas, which is highly toxic if inhaled. Even small amounts of chlorine gas can irritate lungs and airways.

Can Inhaling Clorox Fumes kill you?

Yes, inhaling Corex fumes can potentially kill you. Inhaling concentrated amounts of bleach or prolonged exposure to fumes can lead to respiratory failure and death. Seek immediate medical help if bleach is inhaled.

What does inhaling bleach do to lungs?
