Where to Put a Humidifier When You’re Sick

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.

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.

Side Effects of Electric Heaters- The Good, Bad, and Dangerous

Most people are apprehensive of using an electric space heater because of the obvious things that could go wrong.

And most people make it a point to be extra cautious with a space heater also.

I say most, because most of us probably know somebody that’s making an unwise decision with a space heater right this minute. And I know that is true because of the insane statistics about house fires that have been caused by space heaters.

Statistic…

According to Safety Health and Security Associates

From 2013 to 2015 there was an estimated $45,900 heating fires and 30% of those were caused by space heaters. But electric space heaters are actually a very needed and useful appliance when you know how to use it right.

What are the side effects of an electric heater?What are the side effects of an electric heater?

Advantages of electric room heater

1.  Warmth.

The ability to keep warm is not a small thing. And some situations,  an electric space heater can be the difference between staying warm and developing some serious issues.

Staying too cold for too long can result in problems like:

a. Hypothermia

When your body gets too cold, it can lose heat faster then it can make it.
You can eventually end up with Hypothermia.

Hypothermia is defined as a potentially dangerous drop in body temperature caused by prolonged exposure to cold. It can cause shivering and fatigue, a loss of coordination and confusion. If allowed to continue, it can cause a loss of consciousness. And eventual death.

b. Frostbite

Frostbite can happen when you walk around with cold feet and cold hands all the time. Getting used to your feet being cold and your hands being cold may seem inevitable in some circumstances but it can eventually be dangerous.

c. Trench foot

Trench foot gets its name because of the soldiers and world war I that got stuck in the trenches with wet feet and no way to dry them or keep them warm.

d. Chilblains

Chilblains is a condition that can cause inflammation, blisters, and redness with itching. The cause of Chilblains is is repeat exposure to cold air.

2.  Supplemental heat

When your home has cold areas that the regular heating system just does not suffice, an electric space heater is an excellent way to supplement heat in those areas.

3.  Convenience

Another side effect of using a space heater is how easy it is to produce warm air in your room. Unlike other types of heat that require extensive ductwork and wiring, electric space heaters are ready to go right out of the box.

4.  Cheaper

Electric space heaters do not cost nearly as much to run as the central heat and air and they don’t require the typical filter changes come with HVAC s. And the price for 1 or even a few electric spaces is what’s cheaper than outfitting your home with central heat. And if you don’t need heat through the whole house, you simply run the space heater where you need to heat.

Disadvantages of a space heater

1.  Limited heat

An electric space heater will not heat an entire room with the same efficiency as a gas heater or central heat.

2.  Take longer

Electric space heaters do not heat up a room nearly as fast ducted central heat. And sometimes of electric heaters like oil heaters take even longer.

The positive side of oil heaters is they also take a longer time to cool down which means less energy to run them.

3.  Fire risk

Electric space heaters tend to get very hot. So hot that anything combustible around them is in risk of catching on fire.
The number one reason space heaters catch fire is they are too close to items that can be set ablaze easily.

4.  Power Hogs

Though it is true that running a space heater is much cheaper than Central heating and Air, that does not negate the fact that nearly 100% of all electric space heaters use 1500 watts on high.

That is also the number one reason that space heaters cause the breaker to trip faster than just about any other appliance. At 1500 w, just adding one more appliance to a circuit will trip the breaker.  And the cost of running a space heater on high will average around $7 a day depending on what state you live in.

5. Toasted Skin Syndrome

Toasted Skin Syndrome, also known medically as Erythema ab igne (EAI), is a skin condition that results from prolonged exposure to infrared radiation or heat at lower levels that are insufficient to cause immediate burns but are enough to cause long-term skin damage. This condition is commonly seen in individuals who sit too close to a space heater for extended periods, but it can also occur from using laptops, heating pads, or other heat sources directly on the skin for prolonged times.

Symptoms and Appearance:

  • Discoloration of the Skin: The affected skin may show a reticulated (net-like) pattern of redness and hyperpigmentation. Over time, these areas can become darker and may have a mottled appearance.
  • Burning Sensation and Itching: Initially, there might be mild warmth, tingling, or itching in the affected areas. As the condition progresses, these sensations can become more pronounced.
  • Texture Changes: The skin in the affected area may also undergo textural changes, becoming thicker or showing signs of mild swelling.

Long-term Effects:

  • Permanent Skin Changes: With continued exposure, the discoloration and textural changes can become permanent, and the skin might have a leathery appearance.
  • Increased Risk of Skin Damage: The affected skin may become more sensitive to heat and sunlight, increasing the risk of sunburn and further damage.
  • Potential for Skin Cancer: In rare, chronic cases, there is a risk of developing squamous cell carcinoma, a type of skin cancer, in the affected areas.

Prevention and Management:

  • Maintain Safe Distance: Ensure a safe distance from space heaters and avoid direct exposure of skin to any heat source for extended periods.
  • Use Protective Barriers: If using a heat source for long periods is unavoidable, consider using a barrier such as a blanket or clothing to reduce direct heat exposure.
  • Regulate Heat Exposure: Limit the time spent near heat sources and take regular breaks to prevent prolonged exposure.
  • Seek Medical Advice: If signs of Toasted Skin Syndrome appear, it’s important to consult a dermatologist for assessment and management. Early medical intervention can help manage symptoms and prevent further skin damage.

By understanding and recognizing the symptoms of Toasted Skin Syndrome, individuals can take proactive steps to prevent the condition and protect their skin from long-term damage associated with prolonged exposure to heat sources like electric space heaters.

Safety Measures for Electric Space Heaters:

Safety Feature Description Importance Presence in Electric Space Heaters (Yes/No)
Automatic Shutoff This feature automatically turns the heater off if it overheats, significantly reducing the risk of fire. Crucial for preventing overheating and potential fire hazards. Yes
Tip-over Protection The heater will automatically shut off if it’s tipped over, whether accidentally or due to instability. Essential for preventing fires in case the heater is knocked over, especially in busy areas. Yes
Overheat Protection Sensors that detect when internal components reach unsafe temperatures and shut off the unit. Prevents the heater from reaching dangerous temperatures that could lead to fire. Yes
Cool-to-Touch Exterior The heater’s exterior remains cool during operation, reducing the risk of burns upon contact. Important for safety, especially in homes with children and pets. Yes
Thermostat Control Allows for the adjustment of heat settings to prevent excessive heat and energy use. Helps maintain a safe and comfortable temperature, reducing the risk of overheating. Yes
Timer Enables setting the heater to turn off automatically after a certain period. Prevents the heater from running unattended for extended periods, reducing fire risk. Yes
Non-glowing Elements Heating elements that do not glow red or expose open flames, reducing the risk of ignition of nearby items. Minimizes the risk of igniting nearby combustible materials. Yes
Certified Safety Standards Compliance with recognized safety standards like UL, ETL, or CSA. Ensures the heater has been tested for safety and meets specific safety benchmarks. Yes

 

  1. Automatic Shutoff Features: Be sure to choose space heaters with built-in safety features, such as automatic shutoff mechanisms that activate if the heater tips over or overheats. This is crucial for preventing fires and ensuring the heater does not become a hazard if left unattended.
  2. Certification and Standards Compliance: Only choose space heaters that are certified by recognized safety organizations, such as Underwriters Laboratories (UL), Intertek (ETL), or the Canadian Standards Association (CSA). Certification ensures that the heater has been tested and meets specific safety standards.
  3. Proper Placement: Do not forget the importance of placing space heaters on a stable, level surface away from foot traffic, and at least three feet away from combustible materials like curtains, furniture, bedding, and papers. This minimizes the risk of fires and accidents.
  4. Avoid Using Extension Cords: Use extreme caution with the use of extension cords with space heaters, as they can overheat and potentially cause a fire. If an extension cord is absolutely necessary, be sure to choose a short, heavy-duty one that is rated for the heater’s power requirements.
  5. Supervision and Timers: Never leaving a space heater unattended while in operation. If the heater does not have a built-in timer, suggest using an external timer to ensure the heater turns off automatically when not needed, especially during sleep or when leaving the room.
  6. Smoke Alarms and Fire Extinguishers: Recommend installing smoke alarms in rooms where space heaters are used and checking them regularly to ensure they are working properly. Also, advise keeping a fire extinguisher readily accessible and ensuring household members know how to use it.

    Recap

    There are good and bad side effects to using an electric space heater.

    The good effects include warmth. Not to be understated. Without a way to keep warm, we human beings can be in a world of hurt.

    Electric space heaters provide an excellent service by doing exactly what they are made for. Providing heat. When you stay too cold too long, many issues can arise including hypothermia, and frostbite.

    Electric heaters can also help lower the cost of the bill by supplementing the heat in your house so that you do not have to run the whole house heater the whole time. And unlike other types of indoor heat like chimneys, it is much easier and convenient to plug in a space heater than build a fire or install a whole house system.

    But of course there are some downsides to using an electric space heater.

    The number one downside is the risk of  a house fire.

    People running space heaters too close to combustible items that can ignite are the number one reason of fires caused by space heaters. Space heaters, though in comparison to using the whole house system may not appear to be, but they can be very expensive to run. The typical wattage of a space heater is 1500 watts on high which can result in your bill being as much as $7 higher per day while you’re in the season.

    And there is just no getting around the fact that electric space heaters offer limited heat compared to centralized heat and take much longer to warm a room.

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

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.

Bar chart showing the mineral content in distilled, bottled, boiled, and tap water in ppm, highlighting that distilled water has the lowest mineral content and tap water the highest.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.

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.

Comparison of Indoor Air Quality Issues

Issue Cause Effects on Health Common Solutions
Dry Air Central heating systems heating cold outdoor air Dry and irritated respiratory passages, leading to coughing Humidifiers, hydration stations, steamy showers
Mold Moisture buildup in HVAC systems and ducts Allergic reactions, asthma exacerbation, coughing Regular HVAC maintenance, professional cleaning, UV light purifiers
Bacteria/Viruses Circulation of contaminated air through HVAC systems Respiratory infections, worsening of health conditions UV light purifiers, improved filtration systems, regular cleaning

Harnessing UV Light to Combat Mold in HVAC Systems

While addressing humidity and ensuring regular maintenance are critical steps in preventing mold growth in your HVAC system, another innovative solution is the use of Ultraviolet (UV) light technology. UV light, particularly in the UV-C spectrum, is known for its germicidal properties, effectively inactivating a wide range of microorganisms, including mold spores and bacteria.

How UV Light Works Against Mold

When installed within your HVAC system, UV lights work continuously to purify the air, targeting mold spores and bacteria before they have a chance to circulate throughout your home. The UV-C light disrupts the DNA of these microorganisms, preventing them from replicating and ultimately leading to their destruction. This not only helps to keep the ductwork clean but also improves the overall air quality in your home, reducing the potential triggers for coughs and other respiratory issues.

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.

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.

We cover all the common questions and solutions in our full humidifier guide.

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

Yes — 60% humidity is generally considered too high for a house. At this level, mold and dust mites can thrive, increasing allergy and asthma risks. The ideal indoor range is 40–60%, but once you reach 70% or higher, discomfort, condensation, and property damage become likely — and at 80%, the risks to health, furnishings, and electronics are severe.

Humidity affects your comfort, your health, and even the lifespan of your home’s materials. Below is a quick visual showing the differences between 60%, 70%, and 80% humidity indoors, followed by a breakdown of what each level means and how to fix it.

Infographic showing indoor humidity levels from 40% to 80% with color-coded zones and effects. Green (40–60%) is ideal, yellow (60%) is borderline with dust mite and mold risk, orange (70%) is high with AC inefficiency and allergy symptoms, and red (80%) is very high with severe respiratory issues and property damage.

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

If you’ve breathed in bleach fumes and feel sick, get fresh air immediately. Symptoms like headache, nausea, coughing, or chest tightness are common after cleaning with bleach — especially in small or poorly ventilated areas. Most symptoms pass within hours, but high exposure can be dangerous. Call 911 if you have trouble breathing, chest pain, or confusion.



Feeling sick from bleach fumes? Here’s what to do right now:

  • Get to fresh air: Leave the area and breathe deeply near an open window or outside.
  • Stay calm and rest: Sit down and avoid physical activity. Panic can worsen symptoms.
  • Drink water: Staying hydrated helps your body flush out irritants.
  • Flush eyes or skin: If there’s irritation, rinse with cool water for at least 15 minutes.
  • Call 911: If breathing is difficult, or if you feel dizzy, disoriented, or have chest pain.

Infographic showing bleach exposure levels and what to do if you inhale fumes

Introduction

Many of us know someone who reacts strongly to the harsh smell of bleach. In my household, that person is my wife.

The mere presence of bleach-based cleaning products in our routine triggers an immediate and unpleasant response for her. Even a quick spray to disinfect a countertop or toilet can lead to intense discomfort — an almost instant headache, nausea, and a need to leave the room.

It’s not just about disliking the smell; it’s a physical reaction that affects her ability to function normally.

Over time, we began to notice a pattern: whenever bleach was used, she’d feel sick — sometimes for the rest of the day. That experience made me ask: how harmful is bleach, really, even when it’s just in the air we breathe?

This led me down the rabbit hole of researching bleach exposure and how it affects the lungs, sinuses, and even the nervous system. What I found surprised me — especially how common these reactions are and how few people talk about them. If someone in your home is sensitive to chemicals or already has a respiratory condition, understanding the risks of bleach inhalation is essential.

Why Breathing Bleach Is So Dangerous

Bleach might seem like a simple household cleaner, but it contains powerful and potentially harmful chemicals. Most bleach-based products include sodium hypochlorite, which acts as a strong disinfectant but also creates risk when inhaled.

When bleach is:

  • Mixed with acids (like vinegar or toilet bowl cleaners), it can release chlorine gas
  • Used with ammonia (found in many glass or bathroom cleaners), it forms toxic chloramine vapors
  • Sprayed in closed areas without ventilation, the fumes can become concentrated quickly

Once chlorine gas is released, it reacts with moisture in your eyes, nose, and lungs to create hydrochloric acid and other corrosive byproducts. These can cause immediate irritation and lead to more serious effects, such as:

  • Burning eyes, throat, and nasal passages
  • Coughing and chest tightness
  • Shortness of breath and wheezing

With high exposure or prolonged contact, more dangerous symptoms may develop:

  • Pulmonary edema – fluid buildup in the lungs that restricts breathing
  • Bronchospasms – sudden airway constriction, common in asthma sufferers
  • Asthma attacks – often triggered by even small amounts of bleach fumes
  • Long-term lung inflammation and scarring

People with asthma, allergies, COPD, or other breathing issues are at significantly higher risk. But even healthy individuals can suffer if the concentration of fumes is strong enough or exposure lasts too long.

The bottom line: Breathing in bleach fumes isn’t just unpleasant — it can lead to serious, even life-threatening complications if proper precautions aren’t taken.

Effects of Breathing Bleach Fumes

Exposure to bleach fumes can irritate the eyes, skin, and respiratory tract. The effects depend on the level and duration of exposure — but even short-term contact can cause symptoms.

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

Symptoms and health risks to watch for after inhaling bleach fumes.

Short-term exposure may cause coughing, choking, wheezing, nausea, and burning sensations. Long-term effects like respiratory infections, asthma, lung scarring, and even cancer can occur with repeated exposure — especially in poorly ventilated spaces or when mixing products unknowingly.

Situations Where Bleach Inhalation Occurs

There are several everyday scenarios where inhaling bleach fumes becomes more likely — and potentially dangerous:

  • Cleaning with bleach in enclosed spaces: Using bleach in small, poorly ventilated areas like bathrooms or closets allows fumes to build up quickly, especially when doors and windows are closed.
  • Mixing bleach with other chemicals: Combining bleach with products containing ammonia, vinegar, or acids creates highly toxic gases like chlorine and chloramine. Even small amounts can cause severe respiratory irritation.
  • Bleach spills and accidents: Knocking over a bleach bottle or using too much in a small space can release concentrated fumes and cause burning or irritation to the skin, eyes, and airways.
  • Intentional misuse or self-harm attempts: In rare but serious cases, bleach is used in suicide attempts through ingestion or inhalation. This is extremely dangerous and requires immediate emergency medical care.

Some people also combine bleach with other cleaning agents like baking soda without understanding the risks. If you’re curious about how bleach and baking soda react together, check out our article on what bleach and baking soda are good for — and what they’re not.

What to Do When You Inhale Bleach

Infographic with steps to take after inhaling bleach fumes, including getting fresh air, calling emergency services, removing clothing, and seeking medical help

If you or someone else inhales bleach fumes, it’s important to act quickly. The effects can be immediate or delayed, so even if symptoms seem mild, medical evaluation is often necessary.

Here’s what to do right away:

  • Move to fresh air immediately: Get out of the affected area as quickly as possible to stop further inhalation of fumes.
  • Call emergency services (911): Especially if the person has trouble breathing, chest pain, dizziness, or confusion — these may signal serious exposure.
  • Administer oxygen if available: If you have access to medical oxygen (such as in a healthcare setting), it can help reduce the impact on the lungs.
  • Encourage the person to rest: Avoid physical activity or exertion, which can worsen respiratory symptoms. Keep the person calm and still.
  • Remove contaminated clothing: If bleach has been spilled on clothing, remove it to avoid continued skin and fume exposure.
  • Flush irritated skin or eyes: Use cool, clean water for at least 15 minutes if the person has eye redness, stinging, or skin irritation.
  • Seek medical attention: Even if symptoms appear to improve, lung damage can occur without obvious signs. A medical provider should evaluate anyone exposed to strong bleach fumes.

How to Get Rid of Bleach Fumes

Bleach fumes can linger long after cleaning, especially in areas with poor airflow. To minimize irritation and clear the air effectively, follow these proven steps:

  • Open windows and doors: Start by creating cross-ventilation. Opening multiple windows or doors allows fresh air to circulate and push toxic fumes out of the space.
  • Turn on fans facing outward: Use box fans or exhaust fans to help force the bleach-laden air outside. Position them near windows or doors for maximum airflow.
  • Run your HVAC system: Central air systems can help pull contaminated air through your home’s air filter — especially if the filter includes carbon or HEPA layers.
  • Use an air purifier with a carbon filter: Activated carbon filters are designed to absorb chemical gases and VOCs, including bleach fumes. Place one in the affected area for a few hours.
  • Set out odor absorbers: Place bowls of white vinegar, baking soda, or activated charcoal around the room. These can help neutralize lingering chemical odors naturally.
  • Simmer lemon water on the stove: A natural and pleasant-smelling option — boiling lemon slices in water can help purify the air and mask residual bleach odor.
  • Wait it out in another room if needed: If the space still smells strongly of bleach after ventilating, avoid it until the fumes have completely dissipated to prevent further exposure.

If you accidentally combined bleach with another product (like vinegar or ammonia), the resulting fumes can take longer to clear. Be extra cautious and use fans aggressively to evacuate the area.

How Long Do Bleach Fumes Last?

The duration of bleach fumes in your home depends on several factors — especially how much bleach was used and how well the area is ventilated.

Here’s what typically affects how long the fumes stick around:

  • Amount of bleach used: Heavier applications — like mopping with bleach or scrubbing grout — will produce stronger, longer-lasting fumes.
  • Room size and ventilation: In small, enclosed rooms with poor airflow, bleach fumes can linger for several hours or even up to a day.
  • Humidity and air movement: High humidity can slow down how quickly fumes dissipate. Running fans or dehumidifiers can help speed things up.
  • Surface type: Porous surfaces like grout or fabric may absorb bleach and slowly release its odor back into the air.

In a well-ventilated room, bleach fumes often clear within 30 minutes to 2 hours. In poorly ventilated spaces, however, they may linger for 12–24 hours or more — especially if the chemical wasn’t properly diluted or rinsed off.

Using activated carbon air purifiers and opening windows can significantly speed up the process and improve indoor air quality.

How To Get Rid of a Bleach Headache

bleach headache

A bleach headache isn’t just annoying — it may be a sign your body is reacting to chemical exposure. These headaches are caused by irritation from chlorine gas or vapors released by bleach, especially in unventilated areas.

If you’re experiencing a headache after using bleach, follow these steps:

  • Get fresh air immediately: Leave the room or open windows to reduce continued exposure. Even a few minutes in clean air can start to ease symptoms.
  • Drink plenty of water: Staying hydrated helps your body flush out irritants and supports natural recovery after exposure to chemical fumes.
  • Rest in a safe, ventilated space: Lie down in a quiet, well-ventilated room — preferably one that hasn’t been exposed to bleach — and avoid physical activity.
  • Take over-the-counter pain relievers: Medications like ibuprofen or acetaminophen can relieve headache pain, especially if rest and hydration aren’t enough.

If the headache persists for more than a few hours, or if it’s accompanied by chest tightness, breathing issues, or dizziness, seek medical attention to rule out a more serious reaction.

FAQ

Does inhaling bleach make you cough?

Yes. Inhaling bleach fumes can irritate the lungs and airways, triggering a reflex cough and throat discomfort.

Is it safe to mix bleach and vinegar?

No. Mixing bleach and vinegar releases chlorine gas, which is highly toxic when inhaled — even in small amounts.

Can inhaling Clorox fumes kill you?

Yes, in extreme cases. High exposure to concentrated bleach fumes can lead to respiratory failure or death. Always use bleach with proper ventilation and never mix it with other chemicals.

What does inhaling bleach do to the lungs?

It causes inflammation, swelling, and can lead to bronchospasms or fluid buildup (pulmonary edema) in severe cases. Repeated exposure may cause long-term lung damage.

How long do bleach inhalation symptoms last?

Symptoms like coughing or sore throat may last a few hours. In more severe cases, wheezing and chest tightness can persist for days. Lung irritation may linger if not treated properly.

Can you die from cleaning with bleach?

It’s rare, but possible. Cleaning in an unventilated room or mixing bleach with ammonia or vinegar can produce deadly gases. Use caution and ventilate well.

What does bleach do to your brain?

Inhaled bleach can cause headaches and confusion in high concentrations, but it’s unlikely to cause direct brain damage unless exposure is extreme or paired with ingestion.

How much bleach does it take to kill you?

It varies. Ingesting as little as a cup can be fatal, and prolonged inhalation of strong fumes can cause lethal respiratory distress. Never use bleach in ways it wasn’t designed for.
