What is a Humidifier Ionizer?

Lately a mysterious button has started to pop up on a variety of different appliances.

The “ION” button has made its way onto air conditioners, tower fans, and dehumidifiers. Another appliance that has gotten the Ion treatment is the Humidifier.

What is a Humidifier Ionizer?

An Humidifier Ionizer or sometimes called “Anion” humidifier is a humidifier that disperses negative ions and also disperses moisture. Essentially it is a combination appliance that incorporates a humidifier and an ionic air purifier.

An article in the US National Library of Medicine states that when:

Based on the “Lenard effect”, water shearing appliance has been designed to generate NAIs. Water shearing produced only superoxide ions (O2−) which was bound to clusters of water molecules to form the structure O2−(H2O)n , and was essentially regarded as a natural source of NAIs. NAIs generated by the “Lenard effect” might improve erythrocyte deformability, thereby aerobic metabolism. Also “The ionizer had the ability to kill the bacteria, and ion capture dramatically reduced its bactericidal effect”

In Layman’s terms:

Negative Ions can help reduce airborne bacteria

“Think of negative ions as tiny air cleaners. Just like a magnet attracts metal filings, these ions attach to airborne particles like bacteria. Once attached, the particles become too heavy to stay airborne and settle down, effectively cleaning the air around you.”

What does an ion humidifier do?

An ionizer on a humidifier serves two purposes.

  1. Clean the surrounding air as the humidifier adds moisture to the air. 
  2. Reduce the level of mold and bacteria associated with humidifiers.

Humidifiers are notorious for the amount of cleaning and maintenance they need to ensure that they do not become a breeding ground for mold and other organisms.

Adding an ionizer function to a humidifier can reduce and even destroy much of the contamination related to this issue.

Anion humidifier benefits

  1. Cleaner air
  2. Comfortable humidity levels
  3. Less chance of the humidifier becoming a germ farm
  4. Negative ions make the atmosphere feel lighter

What does an ionizer do in a humidifierHumidifier vs. Ionizer

The purpose of a humidifier is to add moisture to a room. Low humidity is usually associated with winter because the climate is typically more dry during those months.

It’s not only the climate dictating the humidity in the winter, it’s also the fact that the house is usually closed up with the furnace running non stop and drying out the air.

And having the house closed up in the winter introduces more problems than one.

Not only does the air become very dry and miserable especially when you have a cold, the air quality begins to become very unhealthy too.

The first place people start with to solve the problem is buying a humidifier.

A humidifier is a must in the winter. Keeping a cool mist humidifier near your bed in the winter can be the difference between getting a good night’s rest or not.

But a humidifier does not solve the problem of the recirculated air quality in your home becoming a breeding ground of germs on its own.

And compounding the issue is the fact that the humidifier must be cleaned often to keep it from becoming a mold distribution machine all on its own.

When a humidifier gets dirty with mold and other organisms then turned on, it disperses mold spores and bacteria into the air and is able to travel further because it is contained in humidity droplets that act like small vehicles for the germs.

An ionizer is a machine that cleans the air by emitting ions. this works because ions have both negative and positive polarities.

When the ions are dispersed from the ionizer they snap together and trap anything in their way inside of the new bond.

As the new bonds clump together, they become too heavy to float and fallout of the ambient air. (The air you breathe)

Can you use an air purifier and humidifier together?

Absolutely, and you should. Indoor air pollution and dry air are both associated with keeping a house closed up with the heater running.

When the furnace is running non-stop it dries out the air which dictates the need of a humidifier.

Keeping the doors and windows shut to keep the furnace doing its job means that the indoor air quality is suffering.

The air in your house must be kept clean as much as the relative humidity kept in the 30 to 50% range.3 ways a humidifier actually performed as an air purifier.

3 Ways a Humidifier can Clean Air

A Humidifier actually affects the air in more ways than just adding moisture. Humidifiers can also have a cleaning effect on the air, alongside adding humidity.

  • Dust: When the air is dry, dust control can be much more problematic. Adding humidity to the air in a room through a humidifier moistens the dust, causing it to fall to the surface, similar to the cleansing effect of a rainstorm.
  • Viruses and Bacteria: While humidifiers can be a source of germs if not properly maintained, adding humidity can also encapsulate bacteria in humidity droplets, making them too heavy to float and thus removing them from the air.
  • The Lenard Effect: Water can be a source of negative ions through the Lenard effect, which involves the formation of negative ions through shearing water. Although the number of negative ions produced by a humidifier may be small, the potential for ion creation exists.

Humidifier vs. IonizerRecap

Have you ever wondered what the ion button on a humidifier is for? Some humidifiers include an ionizer along with their moisturizing function, dispersing ions into the air to make airborne contaminants too heavy to remain suspended. This means they fall out of the air, effectively cleaning it.

An Anion or Ion humidifier not only adds moisture to the air but also offers the option to add ions, enhancing the air quality. But do they work? Ionizer humidifiers are considered beneficial, especially in closed spaces during winter, combining the benefits of both a humidifier and an ionizer.

These devices often use the plasma cluster ion system, one of the most effective ionizing technologies available. The combination of a humidifier and an ionizer can be more synergistic than, for example, a fan ionizer that might not be as effective due to its fast and hard airflow.

Although ion humidifiers are not widely popular, their unique combination offers a specialized solution for air quality improvement, making them a good option for travelers or for use in environments with varying climates.

Devices like the revitalizer, which uses water shearing similar to the “Lenard effect”, and air washers that use water as a filter, also serve as natural humidifiers with added benefits like aromatherapy.

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

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.

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.

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.

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.

  • Pressed-wood products: plywood, paneling, particleboard, fiberboard
  • Furniture and furnishings made with pressed wood products
  • Carpet
  • Glues and adhesives
  • Permanent press fabrics
  • Paper products
  • Paint and varnish
  • Burning of oil, gas, kerosene, coal, or wood
  • Cigarette smoke
  • Adhesives
  • Foam insulation
  • Wallcoverings

Health Effects of Formaldehyde

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

  • 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.

A girl worried about VOC and chemical exposureThe 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.

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.

 

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

Air purifiers require replacement filters. You cant really argue the amazing capacity of hepa filters to be able to remove allergens from the air. But the ongoing cost of replacing the hepa filter would be considered a major negative side effect of owning an air purifier.

3.  It’s hard to tell if they’re working

Unless you’re having a specific problem with indoor allergies and can pinpoint the exact spot or room where the allergies tend to affect you the most, it’s hard to tell if an air purifier is actually working.

Most of us just go along our daily lives breathing the air we’re given with no real issues. Sometimes owning an air purifier so that we can say we are breathing healthier air is like taking a multivitamin. You know you need it, but you may not even ever be able to tell a difference in the way you are feeling by taking it.

4. Ozone

Air purifiers that clean the air with negative ions and UV tend to make ozone as a by-product. Whether you believe that ozone is straight from the devil or you don’t mind a little ozone if it means you can effectively reduce airborne viruses, the fact remains that breathing too much ozone can aggravate your lungs.

Which kind of defeats the point of getting a machine to help you breathe better.
Most ionic air purifiers create will below the amount of ozone that would be harmful. But there is the problem of putting to large of an ionic air purifier into too small of an area and getting a Overkill of 03.

Ozone also has a sharp odor that is reminiscent of bleach. Another “defeats the point” type of scenario. If you’re using an air purifier to help reduce odors then you  don’t exactly want a machine that adds an odor in return.

5. Make the Room Dusty

Air purifiers tend to make the area around the air purifier extra Dusty. And air purifiers that use negative ions can cause dust to settle throughout the whole area. So much so that there is a term for it, “Grey wall syndrome”.

replace hepa filter6.  Require Regular Maintenance

Maintenance on an air purifier could be considered the same as replacing filters. But there are some types of filters that do not need replacing and can be washed. Most air purifiers have a pre-filter to capture larger airborne debris.

7.  Noisy

Most air purifiers are filtering machines that run similar to a fan that pulls dirty air and exhaust clean air. And just like a fan, they come with different speed settings that allow you to turn the fan up higher or lower. Many larger Hepa air purifiers advertise “white noise” as part of their benefits.

8.  Concentrate germs and bacteria

Air purifiers generally work like a fan in reverse that to pull allergens from the air into a filter. That makes the area around the air purifier that much more full of local debris in the air since the flow of the air is towards the air purifier. This is one of the reasons that sleeping next to an air purifier is not the best ideal.

9. Air purifiers can make allergies worse

Air purifiers can make allergies worse because they tend to pull the airborne  allergens in the room toward the air purifier. This can create a local area around the filter that is highly concentrated with airborne allergens. That’s why putting an air purifier next to your easy chair can actually make the air around your most comfortable seat seem worse.

10. Useless for immediate odors

Though there are many air purifier brands that do work well for removing residual odors with carbon filters, the fact is that air purifiers are pretty much useless to get rid of immediate odors. By immediate, I mean, fresh kitchen odors, chemical odors, or bathroom odors.

11. Useless for smoking

Along the same lines as strong cooking smells, you’re not going to have much luck clearing out the smell of smoke quickly. And if you were talking about a house that has a history of cigarette smoking, the lingering smell is not something that an air purifier will be able to get rid of very easily.
Cigarette and tobacco smoke tends to have a sticky residue texture to it that binds it to the furniture, curtains, walls, and floor.
Ozone generators are you usually used for these types of situations.

clean indoor airAdvantages Of Air Purifiers

1.  Save you money

Allergies are big business. And getting relief from indoor allergies is not cheap.

Antihistamines can run you up to 40 bucks a pop at the local pharmacy. And to get the good stuff you have to have a prescription from a doctor.

Factor in the time missed from work and you get the point. Money and more money.

A quality air purifier can filter out as much as  97% of household allergens.

By capturing airborne allergens before they become a reason to see a doctor or a purchase medication, an air purifier can work to save you money.

2. Great for Babies

Babies are very susceptible to all types of allergens and bacteria.

Using a HEPA air cleaner with a activated carbon filter included will help your baby breathe better without introducing anything into the air that might have an adverse effect.

An Air purifier can also reduce the need for using germ sanitizing wipes in which chemicals can stick around much longer than you might imagine.

Activated carbon in an air purifier can also help reduce the abundance of odors that can gather in the baby’s nursery or room.

Ozone producing air purifiers should be avoided to ensure that the babies developing lungs are not harmed.

There can be no doubt that clean air is important for a baby to grow strong.

do air purifiers work3. Government Statistics  

Statistics. You gotta love em.

But did you know that according to the CPSC Consumer Product Safety Commission,

Indoor air can be more seriously polluted than the outdoor air even largest industrialized cities?

The same research found it people spend as much as 90% of their time indoors and that indoor air pollution is more of a health risk then outdoor air pollution.

Modern building techniques not only provide tightly sealed buildings to better ensure that the temperature remains a constant,

They also keep indoor air pollution sealed inside as well.

Do air purifiers work? Yes, The right air purifier can help you is your family avoid being a statistic.

4. Help Reduce Allergy Symptoms

Allergies affect us all at some point and for some of us, it can be downright miserable.
And the first line of defense is usually  to get an allergy medication.

Medications like antihistamines are expensive and most people experience side effects like fogginess and feeling drowsy when using them.

A high quality air purifier can work to filter as much as 97% airborne dust, pollen and pet dander, mold spores and bacteria before they have a chance to turn into an allergy problem.

5. Reduce Asthma Tiggers

Many of the same household allergens like dust mites and pollen, mold spores and pet dander can result in much worse symptoms for an asthma sufferer.

Airborne pollutants that otherwise may be the norm can result in narrowed airways and not being able to your catch your breath for an  asthmatic.

Reducing triggers that can cause an attack is essential for an asthma sufferer.

A good air purifier can go a long way to help reduce airborne asthma triggers.

woman with pets6. Help Control Pet Dander

How many people have to alter their lives because they can’t exist in the same house as a cat?

Pet dander can produce awful symptoms in people that are allergic to it.

Uncontrollable sneezing and swollen eyes are typical for people allergic to dander.

What a lot of people do not know though, is that airborne pet dander can be controlled.

Dander is actually the bacteria left on a Pet’s fur after they lick and groom themselves.

Once it dries, it becomes airborne.

An air purifier with a true HEPA filter can work wonders when it comes to capturing pet dander out of the air.

7.  Germs and Bacteria Reduction

Controlling germs and viruses in the home is usually delegated to using antiseptic sprays and bleach wipes.

But according to the National Library of Medicine, there are air cleaning technologies that can leave viruses and bacteria inactive.

Bi polar ionization is a technology that when used in concert with a HEPA filter can effectively reduce germs and viruses in a room.

Adding an air purifier equipped with these technologies to your sanitizing arsenal can make a real difference when it comes to germs and viruses in your home.

8.  Mold Spores

A great deal of the population is allergic to mold spores.

Many of the problems that people have with mold or due to leaky pipes. Finding the area where the moisture is getting in and fixing it is the first step to control mold allergies.

But there are also many other areas that mold grow that are practically impossible to eliminate.

Though the use of an air purifier will not clean mold off of your walls, it can be very effective at reducing the populations of mold spores in your air.

One type of air purifier that is highly rated for reducing mold in the air is Photocatalytic Oxidation. Photocatalytic oxidation or PCO for short oxidizes mold spores and removes their ability to cause an allergic reaction.

do air purifiers work for pet allergies9. Odors

Foul odors or not only annoying and off-putting, they can be symptomatic gases and fumes lingering in the area.

Activated carbon is a type of air cleaning technology that is able to adsorb the the VOCs and gases that are at the root of the odor and leave your house feeling fresh again.

Do Air Purifiers Work? Yes, The Right Air Purifiers Really Work For Odors.

10. Help With Headaches

Dust in air can give you a headache. But it’s not just the dirt being kicked up in the air that’s the problem.

It’s what the dust is made up of.

Some of the ingredients that you can find in your average dust ball are dead skin cells, cockroach feces, dust mites, pollen and spores, and carcinogens from smoke.

No wonder you have a headache.

Intense smells can also give you a headache. Many people can develop an oversensitive sense of smell they can make even the smells like cologne and candles too strong.

An air purifier that uses a true HEPA filter and an activated carbon filter can be a game-changer when it comes to reducing airborne contaminants that cause headaches.

11. Help Manage COPD

Chronic Obstructed Pulmonary Disease or COPD is a lung disease that causes obstructed airflow to the lungs.

An air purifier is not a replacement for inhalers and other equipment for people with COPD but keeping the air as clean as possible is a must when everyday household allergens can interfere with catching your breathe.

Keeping quality air purifiers equipped with true HEPA and activated oxygen filters running throughout the home will help remove airborne irritants before they have a chance to be breathed in.

12. Chemicals and VOCs

VOCs are usually considered air pollution created by chemicals.

Many household products including hair spray, aerosol cleaners, nail polish remover, and crafting items like paint and glue can be toxic to breathe.

Other VOCs occur through off gassing, exhaust fumes, and cigarette smoke.

Symptoms of VOC exposure range from allergy type issues like sneezing and runny noses all the through sharp headaches and memory loss.

Air purifiers that contain a large weight of activated Carbon are what’s needed to combat Chemicals in the air.

Other technologies like PCO reduce VOCs as well. Be aware though that air purifiers that rely on creating a ionic reaction should be viewed more as a air cleaning treatment rather than a 24/7 filtering machine.

Dehumidifier vs. Fan for the Bathroom – Which Reigns Supreme?

Using a dehumidifier or a fan for indoor humidity?

Which one is better?

Excessive humidity inside of your home can happen for multitude of reasons including flooding, leaks, poor insulation especially in the basement and crawl spaces, or the rainy season has just descended on you.

But the most common place that you find excessive moisture in the air is the bathroom.

Regardless, living with high humidity inside of the house not only effects your  level of comfort and overall wellness, it also effects the structure of your home as well as your belongings.

Comparison Table: Dehumidifier vs. Fan

Feature Dehumidifier Fan
Method of Operation Extracts moisture from air Improves air circulation
Energy Efficiency Varies; Energy Star models available Generally energy-efficient
Suitability for Room Size Good for large and small spaces More effective in smaller spaces
Maintenance Required Regular cleaning and tank emptying Minimal; occasional cleaning
Noise Level Can be quiet to moderate Usually quiet
Cost Moderate to high Low to moderate

 

Dehumidifier vs. fan 

A fan can be useful to reduce indoor humidity as long as it is blowing dry outdoor air into the room, but it is not controlled or measured.

On the other hand, a dehumidifier will reduce a controllable , measured amount of humidity and does not depend on the outside air being dry.

If you have an issue with high humidity inside of your home, the humidity outside is more likely going to be very high than low.

In a circumstances where the humidity is not overbearing but not exactly helping you out either, placing fans around the room can have a drying effect on the air.
If you were trying to paint or some other type of similar art project where you need a dry environment, having a couple of fans osculating and moving air around the room can probably give you the amount of dryness you need for your project.

But other indoor humidity issues, like a damp basement, you need a way to control the amount of humidity in the room because of the problems of mold and fungus it comes with it.

The only way you can get this type of control is by using a dehumidifier that will extract the humidity out of the air to the proper relative humidity is reached.

Dehumidifier vs exhaust fan

Dehumidifier vs exhaust fan

Most people have exhaust fans in their bathrooms so that the moisture left in the air by the shower and bath can be expelled out of the house so but it does not have a chance to promote mold in the drywall and window frames.

But though you typically do fine exhaust fans in the bathroom and the kitchen, they are really not found too much in other areas of the house.

Dehumidifiers and fans or exhaust fans are not enemies. Nor do they have to work exclusive of each other.

Using the exhaust fans in the bathroom in the kitchen or a great idea and do a great job. But they do not work for the whole house.

A Dehumidifier can only help an exhaust fan to reduce the humidity in the house. Likewise, exhaust fans can only help with the dehumidifier do its job.

“The main difference is that a dehumidifier can extract and remove the exact amount of humidity that you need it to whereas a fan doesn’t have the capacity to be measured.”

Humidity Control Methods in Different Areas of the Home

Area of Home Best Humidity Control Method Pros Cons Recommended Products
Bathroom Exhaust Fan Directly expels moist air, Quick moisture removal Limited to localized area In-built or additional exhaust fans
Basement Dehumidifier Effective for large spaces, Precise humidity control Requires regular maintenance, Higher cost Any large capacity dehumidifier
Kitchen Exhaust Fan Removes cooking steam and moisture, Helps prevent mold Not suitable for whole house humidity control Standard kitchen exhaust systems

 

The second way a fan can help a dehumidifier is the use of a high-powered air mover fan. An air mover is a fan created especially for drying and is usually used on construction sites as a means of speeding up the time it takes for paint to dry and blowing away the fumes left behind by the paint.

An air mover is not generally a piece of machinery that you’ll want to use in your home unless you plan on removing everything from the walls and putting everything away that can be blown away.

Recap

A fan and a dehumidifier can both help reduce humidity in the air but the difference is, it is the job of a dehumidifier to remove humidity from the air and it does so according to how it is programmed.

A Fan on the other hand, even though it does have some drying capacity because oh the natural blowing on something to dry it aspect, does not extract humidity from the air and does not do nearly as good of a job as reducing humidity as a dehumidifier. Nor is it measurable or controllable like a dehumidifier.

One exception is an exhaust fan that is put inside of a bathroom or kitchen for the express purpose of removing moisture created by showering and cooking. Another exception is the use of a commercial air mover, which is a high velocity fan meant that is used to help dry out construction sites as well as remove fumes.
Yet even in these cases it’s not measurable or controllable.

But as a fan, a dehumidifier is only good for blowing hot air on you. Not usually the effect you want from a fan.

FAQ

Q1: What Causes Indoor Humidity?

A1: Indoor humidity can be caused by weather, daily activities like cooking and showering, and structural issues like poor ventilation and insulation.

Q2: How Do Dehumidifiers Work?

A2: Dehumidifiers draw moist air, cool it to condense moisture, then reheat and circulate dry air back into the room.

Q3: What Are the Benefits of Using a Fan for Humidity Control?

A3: Fans reduce humidity by improving air circulation and accelerating moisture evaporation, effective in smaller rooms.

Q4: When Should I Use an Exhaust Fan Instead of a Dehumidifier?

A4: Use an exhaust fan in areas like bathrooms and kitchens where moisture is generated rapidly. A dehumidifier is better for continuous control in larger areas.

Q5: Can I Use Both a Dehumidifier and a Fan Together?

A5: Yes, combining a dehumidifier and a fan can efficiently control humidity, as the fan circulates the dry air throughout the room.

Q6: What Is an Air Mover, and How Does It Differ from Regular Fans?

A6: An air mover is a high-velocity fan used for industrial purposes like drying construction sites, not typically for residential use.

Q7: How Do I Choose the Right Dehumidifier for My Home?

A7: Choose based on area size, humidity level, and features like noise level or energy efficiency. Larger spaces need higher capacity dehumidifiers.

Q8: What Maintenance Does a Dehumidifier Require?

A8: Dehumidifiers need regular tank emptying, filter cleaning, and occasional coil cleaning for optimal performance.

Q9: Are There Energy-Efficient Options for Humidity Control?

A9: Look for Energy Star rated dehumidifiers and fans, and employ natural ventilation to save energy.

Q10: How Can I Naturally Reduce Humidity Without Devices?

A10: Use natural methods like increasing ventilation, moisture-absorbing plants, and fixing leaks for humidity reduction.
