The Best Air Purifier for Cannabis Smoke & Smell

Cannabis plant with smoke around it air purification

As with other types of smoke, marijuana smoke creates tenacious residues and odors. Similar to cigarette smoke, marijuana smoke can offend non-smoking neighbors and guests, and residual odors can alert others to the habit.

The legalization of cannabis for both medical and recreational purposes in the United States and Canada has made it much more accessible and accepted than it was previously. In the US, 37 states now allow access to medical marijuana while 21 states have legalized recreational use. Canada has also legalized recreational use of cannabis.

Whether someone smokes cannabis for recreational or medicinal purposes, cleansing the air after smoking is usually a good idea. The right air purifier can cleanse indoor air of both harmful particles and unwanted smells from marijuana smoke.

Pollutants in cannabis smoke

Cannabis smoke contains two types of pollutants: particulates and VOCs (volatile organic compounds). While there are no cannabis odor control requirements listed by the Government of Canada for residential areas, the United States Environmental Protection Agency recommends ventilating thoroughly when using products that impact the quality of your indoor air.


Particles in marijuana smoke usually fall into the category of microscopic ‘liquid particles’ which are easily inhaled deep into the lungs and can cause lung disease in the long term.

Volatile Organic Compounds

The VOCs in cannabis smoke are similar to those found in other types of smoke, such as cigarettes and wildfires. These gaseous chemicals include carbon monoxide, nitrogen oxides, benzene and formaldehyde, among hundreds of others. Exposure to VOC’s has been known to cause:

  • Visual disorders and memory impairment
  • Eye and respiratory tract irritation
  • Headaches
  • Dizziness
  • Disease

Minimize your exposure to the chemicals in cannabis smoke

There are a few ways you can minimize your exposure to the more harmful products in cannabis smoke.

If possible, smoke near an open window or fan. Reduce the amount of paper used to produce less smoke overall. This also allows you to inhale the active compound THC while minimizing exposure to other chemicals.

You can also clean your home frequently to avoid the build-up of toxic products in furniture, carpets and upholstery.

The fewer chemicals you inhale, the lower your risk of associated side-effects. Using the right air filter can mean exposing yourself to fewer toxins after you’ve finished smoking.

Which type of air purifier is best for cannabis smoke?

There are a variety of air purifiers on the market. Here is a quick look at which air purifiers work for cannabis smoke.

HEPA filter

HEPA (High Efficiency Particulate Air) filters are widely acknowledged to be the most effective filters for eliminating particulates from the air. Made from a very fine paper, a HEPA filter traps over 99% of allergens from the air, including dust, pollen, smoke particulates, bacteria and pet dander.

Unfortunately, an air purifier with a HEPA filter will not be able to capture VOCs. However, an air purification unit that combines a HEPA filter and a carbon filter will guarantee you clean, healthy indoor air.

Carbon filter

An active carbon filter contains carbon that has been exposed to high heat, which causes it to become more porous. Carbon filters remove chemicals and some particulates from the air.

Used alone, an active carbon filter will be less efficient than when used in tandem with a HEPA filter. Together, these filters will remove both visible smoke particles and invisible airborne toxins from your indoor air, making this type of residential air purification unit your best choice for eliminating cannabis smoke and smells.

UV light air purification

Other types of air purifier can also get rid of smells quickly and efficiently, including the smell of marijuana smoke. Recently developed UV light air purification technology uses UV rays to eliminate VOCs, chemicals, odors, mold, viruses and bacteria from indoor air.

While UV units may be best suited to commercial facilities, including growers,  they are a state-of-the art method for cleansing and purifying indoor air that is safe, eco-friendly and affordable.

Get rid of cannabis smoke quickly

Remember, the longer cannabis smoke remains in the air, the more likely it is to damage your health and surroundings. In addition to bad odors, tiny particles from marijuana smoke can create a sticky brown dust that damages your walls, clothing and furniture.

Turn on your air purifier immediately or set it to start automatically for best results.

Reduce cannabis smoke and smell with a Sanuvox air purifier

Cleaning your home regularly can help to reduce lingering marijuana smoke and smells, but to be sure you are breathing fresh, clean air indoors after smoking, the most effective solution is to install an air purifier.

Do Air Purifiers Work for Eczema?

Eczema and air purifiers

Eczema is a chronic inflammatory skin condition that is commonly found in children, but may occur at any age. Eczema is two to three times more prevalent now than it was 30 years ago, particularly in urban areas, leading scientists to believe that its development may be related to high levels of pollution.

While there is no cure for eczema, it can be managed. A major part of any management strategy is identifying which environmental pollutants (triggers) are likely to cause flare-ups, and avoiding them. This is where air purifiers can help!

What is eczema?

Eczema is a chronic condition that affects the skin. Common symptoms include itchiness, rash, and dry, cracked skin. Persistent scratching often leads to skin infections, thickening and discoloration.

People with eczema usually experience flare-ups, periods of time when their symptoms are acute, which can last for days or weeks on end. The triggers that cause flare-ups differ from person to person.

What causes eczema?

In most people, skin acts as a protective barrier that prevents bacteria, allergens and irritants from entering our body. In people with eczema, the skin’s barrier function is weakened as a result of genetics or other factors. The weakened skin is less able to retain moisture and protect the body from environmental pollutants. When encountering such elements, the immune system goes into overdrive and creates inflammation as a natural defense mechanism.

What air purifiers can do

Air purifiers are designed to improve indoor air quality by removing a variety of environmental pollutants from the air. Residential air purification systems can help people with eczema limit their exposure to potential environmental triggers.

Common eczema triggers

Extreme temperatures can exacerbate skin dryness and irritation in people with eczema, and emotional stress is also known to cause flare-ups. However, most triggers are common allergens and irritants—eczema often co-occurs with allergies and asthma, and is susceptible to similar contaminants. These include:

  • Dust mites
  • Pet dander
  • Mold
  • Pollen
  • Cigarette smoke
  • Cleaning products
  • Fragrances

How air purifiers help with eczema triggers

Studies have shown that eliminating environmental chemicals and pollutants that are known triggers from the air can improve eczema symptoms. There are a few different types of air purifiers, each of which has its own particular mechanism for removing contaminants. If you have eczema and want to purchase an air purifier, it’s important to determine what your triggers are and find out which air purifiers are most effective against them so you can select the device that’s right for you.

Air purifiers with HEPA filters

A HEPA filter is a finely-woven mechanical filter that traps 99.97% of even the most penetrating airborne particles. This type of air purifier effectively reduces dust, pollen, pet dander, mold and other physical particles that often provoke an immune response.

Since the HEPA filter traps the particles as air passes through, it will eventually become saturated with contaminants. People with eczema should take care when cleaning or changing out the filter—either have someone else do it or make sure to use gloves.

Air purifiers with activated carbon filters

Activated carbon filters are treated with oxygen to make them very porous. The increased surface area creates more chemical attraction, so that airborne molecules adhere to the filter as the air passes through. This type of air purifier captures VOCs, cigarette smoke, perfume and other chemicals and odors that can’t be trapped by physical means.

As more and more molecules stick to the activated carbon filter, it will eventually become saturated and cease to work, at which point it will need to be replaced.

UV air purifiers

UV light air purifiers use high-intensity UVC and UVV wavelengths to destroy airborne contaminants. UVC is a germicidal wavelength that deactivates viruses, bacteria and other microorganisms, while UVV degrades chemicals and odors through oxidation.

The UV process is unique among air purifiers because it actually destroys the pollutants rather than simply trapping them. UV air purifiers also tend to be able to cover larger rooms than other types of air purifiers.

Other flare-up prevention methods

As previously mentioned, one of the most important steps people with eczema can take to prevent flare-ups is to determine what their triggers are and do their best to avoid them. It’s also vital to diligently follow a good skin care routine:

  • Shower every day to keep your skin clean, but limit how much time you spend in the shower and how hot the water is
  • Use non-soap cleanser and avoid scrubbing with a washcloth or loofah
  • When you get out of the shower, gently pat yourself dry rather than wiping or rubbing
  • Moisturize your body within three minutes of getting out of the shower, while your skin is still damp
  • Moisturize at least twice a day

Remember that even the best home management solutions can’t take the place of professional advice. If you have eczema, it’s best to consult a dermatologist who will be able to come up with a treatment and management plan that is tailored to your needs.

Keep pollutants at bay with Sanuvox!

Eczema is a condition that can cause severe discomfort. If you have eczema, you may be scouring the internet for anything that might help alleviate your symptoms or prevent flare-ups.

Do Air Purifiers Help Remove VOCs?

Perfect air quality no VOCs

Volatile organic compounds (VOCs) are common gaseous chemicals that are difficult to avoid in indoor spaces and can have adverse health effects. Fortunately, some types of air purifiers are effective at trapping or deactivating these airborne pollutants. Discover the best air purifiers for VOCs in this article!

What are VOCs?

Volatile organic compounds are a large group of chemicals that vaporize easily at room temperature. While they are found in both indoor and outdoor air, concentrations indoors are usually up to ten times higher, significantly lowering air quality. Many common household and workplace products emit VOCs in a process known as off-gassing.

Common sources of VOCs in households and workplaces

  • Cooking
  • Cigarette smoke
  • Candles and incense
  • Air fresheners
  • Cleaning products
  • Paint
  • Glues and adhesives
  • Building materials and furnishings
  • Office equipment such as copiers and printers

Health consequences of VOC exposure

Exposure to volatile organic compounds can have consequences for your health, depending on the type of VOC, concentration and exposure time. Children, seniors, pregnant people and those with pre-existing health conditions such as asthma are particularly susceptible.

Exposure to VOCs can cause headaches, nausea, and nose and throat irritation that can lead to nasal congestion and sinus problems. In severe cases, exposure may lead to liver, kidney and central nervous system damage or cancer.

The best air purifiers for VOCs

Not all types of air purifiers are effective at removing VOCs from the air. While HEPA filters are widely considered to be the air purification gold standard, they are designed to trap physical particles, so harmful gases are likely to pass right through. Fortunately, there are other types of commercial and residential air purification systems that work better against VOCs.

Air purifiers with activated carbon filters

Activated carbon filters use porous carbon material to trap VOCs and gases through a process called adsorption. As air passes through the filter, the contaminant molecules get stuck to the substrate and the cleaned air is released back into the room. These types of air purifiers are also great at getting rid of unwanted smells.

UV light air purifiers

Some residential and commercial UV air purifiers are designed to emit UVV wavelengths that degrade chemicals and odors by oxidation. Air is drawn into a chamber and subjected to high-intensity UVV rays before being released back into the room. The UV process is very effective at breaking down VOCs.

Remove VOCs with Sanuvox!

While it’s a good idea to try to limit the number of VOC-emitting products in your space, it is virtually impossible to eliminate them entirely. The right air purifier can help mitigate the effects of off-gassing and ensure that VOC levels remain low.

Sanuvox offers UV light air purifiers that effectively combat volatile organic compounds and odors. Our powerful air purifiers are rated for large rooms, and some can even cover an entire apartment or house! Contact us today to lower VOC levels in your space and safeguard your health.

Do Air Purifiers Help Nasal Congestion (Stuffy Nose)?

stuffy nose air purifier

Your nose is your body’s first line of defense against the various irritants commonly found in the air we breathe. Your nasal passages are lined with hair and cilia that are designed to trap these intruders before they can make it into your airways. Unfortunately, this natural defense system isn’t perfect, and irritants sometimes make it through, causing inflammation and congestion. An air purifier can help trap airborne contaminants so that your nose doesn’t have to!

What causes nasal congestion?

When contaminants make it past the first line of defense, they can irritate your nasal tissues, causing inflammation and triggering your immune system to produce more mucus in an attempt to flush out the intruders. The swelling and additional mucus create the feeling of a stuffy nose and make it more difficult to breathe.

There are several types of irritants that can cause nasal congestion:

  • Viruses and bacteria can cause infections such as colds, flu and sinusitis that trigger an immune response.
  • Allergens are triggers that make the immune system overreact and release histamine, a chemical that causes inflammation, sneezing and other processes designed to expel the perceived threat from the body.
  • Odors and chemicals can also irritate the lining of the nose and throat, leading to inflammation and congestion.

How air purifiers can help with nasal congestion

Air purifiers help prevent nasal congestion by removing irritants from the air you breathe. There are a few different types of filtration and purification mechanisms that work best on different types of contaminants.

UV air purifiers

UVC air purifiers emit a specific wavelength of ultraviolet light that deactivates and help to destroy viruses, bacteria and other microorganisms. Fans push the airstream past high-intensity lamps that cleanse the air before sending it back out into the room, reducing the likelihood of infection.

Air purifiers with HEPA filters

HEPA filters are mechanical filters that use finely woven mesh to trap particles. These types of air purifiers effectively trap allergens such as dust, pollen and pet dander that commonly circulate in households and are a major source of airway irritation and nasal congestion. Note that HEPA filters eventually become saturated with contaminants and must be cleaned or changed regularly to maintain their effectiveness.

Air purifiers with activated carbon filters

Activated carbon filters chemically attract odors and pollutants through a process called adsorption. These types of air purifiers work well on volatile organic compounds (VOCs), cigarette smoke smell and other common irritants. These filters also become saturated eventually and must be replaced.

Eliminate airway irritants with Sanuvox!

If you are suffering from a stuffy nose, the first thing to do is to determine what’s causing the irritation. Ideally, you’ll want to minimize your exposure to whatever is triggering your immune response. The right air purifier will help alleviate your sinus problems by eliminating contaminants and improving the air quality in your home.

If you’re concerned about pathogens circulating in the air, consider investing in one of Sanuvox’s residential UV air purifiers. We also offer air purifiers for the entire house that are equipped with multiple filtration and purification mechanisms to cover a wider range of airborne irritants. Contact us today to improve your air quality and alleviate your nasal congestion!

Can an Air Purifier Help with Snoring?

Snoring reduced with an air purifier

Sleeping well is a vital part of maintaining your physical and mental health. Whether you snore or sleep with someone who does, snoring can be very disruptive to your sleep cycle and general well-being. If you’re looking for snoring remedies and wondering whether an air purifier might help, you should know that its effectiveness will depend on the underlying cause of the snoring.

What causes snoring?

When you fall into a deep sleep, the muscles in your mouth, tongue and throat relax. As they relax, the tissues in your throat may partially block your airway, vibrating as the airflow passes through and creating a snoring sound. The obstruction may be caused by a variety of factors:

  • Anatomy: Having a low or thick soft palate, a big tongue, an elongated uvula or large tonsils means more tissue in your throat that may cause a blockage as it relaxes.
  • Obesity: People who are overweight are more likely to have an increased amount of tissue in the throat.
  • Sleep position: Lying on your back allows gravity to pull your tongue back towards your throat as your muscles relax.
  • Substances: Alcohol and sleeping pills can cause your muscles to relax more than they would otherwise.
  • Airway irritation: Allergens and other airborne contaminants can irritate your airways and inflame your throat tissues. This is where having an air purifier in the house can help!

Obstructive sleep apnea

Note that severe snoring may be a symptom of obstructive sleep apnea, a serious sleep disorder where the airways become blocked enough to deprive the body of oxygen. If you suspect that you might have obstructive sleep apnea, symptoms of which include loud snoring, gasping for breath while asleep and daytime fatigue, talk to a medical professional.

How air purifiers can help with snoring

Air purifiers can help you sleep better and ease your snoring if you suffer from airway inflammation caused by airborne contaminants. Air purifiers are designed to remove allergens such as pollen, dust, and pet dander from the surrounding air. Some types of residential air purifier systems are also effective against other irritants such as chemicals and cigarette smoke.

Air purifiers work by pulling contaminated air in, passing it through a fine mesh filter and/or other purification systems to eliminate the contaminants, and returning clean air to the room. The improved air quality should help alleviate the inflammation and consequently, the snoring. The devices are exceptionally quiet but emit a low level of background white noise, which may help partners disturbed by the sound of snoring.

Breathe deep for sound sleep with Sanuvox!

If snoring is disrupting your sleep or your partner’s, it’s best to get to the bottom of what is causing your airway obstruction. If airway inflammation is the culprit, using an air purifier to reduce airborne contaminants may provide some relief.

Sanuvox is a global leader in UV air purification systems. Our patented UV purification process effectively destroys airborne pathogens and degrades chemicals and odours that may be irritating your airways. We also offer devices that include HEPA and activated carbon filters for additional particle and chemical filtration. Contact us today for air purifiers that truly make a difference!

Do Air Purifiers Cause Sinus Problems?

Woman with sinus problems and air purifier

While sinus problems aren’t usually severe, there’s no question that they can be extremely unpleasant. You may be suffering from dry nasal passages that bleed at the slightest provocation, or stuffy, blocked sinuses that cause painful headaches and make it difficult to breathe.

Looking for the source of your discomfort and wondering whether your air purifier might be the culprit? Find out everything you need to know about how air purifiers affect the sinuses in this article.

The most common causes of sinus problems

Sinus problems can be caused by a number of different factors. Humidity, for one, can have a significant impact on sinuses. Particularly in winter in colder climates, indoor heating can really dry out the air and make it difficult for our nasal passages to stay lubricated. This can lead to irritation, discomfort, nosebleeds and more.

Airborne irritants such as allergens and chemicals are often at the root of sinus problems. This category includes many types of particles that are common in homes and difficult to avoid entirely. Particularly for those with sinus and/or respiratory tract sensitivity, inhaling these contaminants can easily cause inflammation and congestion.

It goes without saying that infections and illnesses can also wreak havoc on our sinuses.

How air purifiers work

Air purifiers use a fan to pull air in from the room and pass it through some type of purification mechanism, which may include HEPA filters, activated carbon or a UV disinfection process. Once the air has been cleansed, they release it back into the room.

Do air purifiers dry out the air?

Air purifiers do not dry out the air. In fact, they don’t affect indoor humidity levels at all. They simply circulate the air and remove contaminants. Depending on the placement of the air purifier, the air may feel a little dry if the fan is blowing too close to you, but it won’t actively affect humidity. If you think dry air in your home is causing your sinus problems, consider investing in a humidifier to add some moisture to the space.

How air purifiers can help with sinus problems

Air purifiers don’t cause sinus problems. In fact, they can actually help if the problems are caused by airborne irritants. Air purifiers filter out the dust, pollen and dander that may be triggering your allergies and inflaming your sinuses. Some types of air purifiers can also trap or degrade VOCs, paint fumes and other irritants. Residential UV air purifiers can even deactivate viruses and bacteria in order to lower your risk of getting sick!

Breathe cleaner air with Sanuvox

Your air purifier may not be at the root of your sinus problems, but it’s a good idea to find out what is. Particularly if your symptoms are severe, consider discussing your situation with a medical professional to get to the bottom of what’s causing your discomfort.

If you’re interested in reducing the amount of airborne irritants in your home and breathing cleaner air, consider investing in a UV light air purifier from Sanuvox. We offer a range of large room and whole house air purifiers that are designed to destroy harmful microorganisms, degrade chemicals and improve air quality. Contact us today!

Do Air Purifiers Help With Radon?

Radon Warning Sign

Radon is a common household hazard that is often overlooked. While it is fairly harmless in low amounts, high concentrations are associated with an increased risk of cancer. It’s important to be aware of the hazard, know how it can be detected and what can be done to mitigate it. Find out those answers and whether air purifiers can contribute to mitigating radon in this article!

What is radon?

Radon is a colourless, odourless and tasteless gas that is produced as natural radioactive elements in the soil decay. Being an inert element of the periodic table, radon always remain mono-atomic and does not chemically bond or react with any element. Radon is generally harmless when dispersed into the air outside, but it can easily accumulate indoors and reach dangerous levels.

The air pressure inside buildings is generally lower than in the surrounding soil. The difference in pressure draws air and other gases into the building. Radon can enter easily through cracks in the foundation and other openings where the building is in contact with the ground.

Health risks associated with radon

After smoking, radon is the second leading cause of lung cancer in Canada and the United States. When radon gas is inhaled, the radioactive elements continue to break down inside the lungs, releasing small bursts of energy that damage the lung cells and can lead to cancer as they reproduce.

The risk of cancer depends on the level and duration of radon exposure. Smoking in conjunction with radon exposure is linked to a much higher risk of lung cancer.

Do air purifiers help with radon?

When it comes to trapping ambient gases, not all air purifiers are created equal. Those equipped with HEPA filters are designed to mechanically trap particles such as dust, pet dander and mold. The best air purifiers for smells, VOCs and gases are those equipped with activated carbon filters, which chemically attract the molecules, and UV light air purifiers, which degrade them.

Because Radon is chemically inert, no air purifiers can help mitigate it.

Radon mitigation measures

Testing for radon

The first vital step is to test the air quality in your home to determine the levels of radon present. This can be done either by a professional or with the help of a DIY home test kit. When testing yourself, it’s best to do so over a longer period of time (3 months or so), because radon levels can fluctuate according to several factors, including the time of year.

If your test detects radon levels above the Canadian guidelines, steps should be taken to reduce them. The higher the concentration of radon, the sooner you’ll need to act.

Professional radon mitigation

The gold standard for dealing with a radon problem is to hire a professional, particularly when faced with high levels of the gas. A professional radon mitigation system can be installed in under a day and will reduce radon levels by up to 90%.

Increasing home ventilation

Increasing ventilation in the home can lower radon levels by 25 to 50%. That being said, the effectiveness of this strategy has its limits. Therefore, it should only be used as a complementary measure or in situations where the required reduction in radon levels is minimal.

Sealing cracks in the foundation

Since radon comes from the ground and generally seeps through cracks and holes in the foundation, sealing these entry points can help stop the gas from entering your home in the first place. Sealing cracks can also prevent other problems such as water infiltration and pest incursions. However, this method can only reduce radon levels by about 13%.

Breathe cleaner air with Sanuvox

While air purifiers aren’t effective against radon, they can improve the air quality in your home in many ways. The right air purifier can cleanse the air you breathe of particles like pollen and dust, harmful chemicals and microorganisms, improving your health and quality of life.

Should an Air Purifier Run All the Time?

air purifier running all day settings

If you have invested in an air purifier, it’s safe to assume that you care about the quality of the air in your home and how it impacts your health. However, there are other considerations that must also be taken into account, such as how much electricity the device uses and the resulting impact on the environment.

In this article, find out everything you need to know to make an informed decision about whether or not to leave your air purifier running.

How long do air purifiers take to work?

It can take anywhere from half an hour to several hours for an air purifier to eliminate contaminants and improve the air quality in a room. How long your air purifier takes to work will depend on several factors, including the size of the space you want cleaned, the setting you use and the amount of pollutants in the air. It’s always best to select an air purifier that is rated as close as possible to the size of the space you plan to use it in—otherwise, it may not function as effectively.

Unfortunately, an air purifier’s job isn’t done once the air in the room is clean. Contaminants will continue to accumulate in the air, meaning that the air purifier must work continuously to eliminate them. Once you shut the device off, unwanted pollutants like dust, pet dander, pollen and bacteria will return within a few hours.

Is it safe to run an air purifier all the time?

Residential air purifier systems are designed to run continuously, so there is no danger in keeping them running, even when you are out of the house or asleep.

What is the energy cost of running an air purifier all the time?

The energy cost of running an air purifier continuously is surprisingly low. Even a powerful whole house air purifier that covers up to 4,000 sq. ft. can cost just $0.27 a day, and that’s when run continuously on the highest setting.

To save electricity, you can switch the device to a lower setting once it has been running for a couple of hours. There are even air purifiers that are able to test the ambient air quality and automatically adjust the setting accordingly!

Enjoy the benefits of cleaner air with Sanuvox!

As you can see, the drawbacks of leaving your air purifier on all the time are minimal. It’s perfectly safe to keep the device running continuously, and the amount of energy it consumes is very small. And the advantages are significant—by running your air purifier all the time, you’ll benefit from the best air quality possible, and the cleaner the air, the better for your health!

Sanuvox is a global leader in UV air purification systems. Our air purifiers use high-intensity UV rays to deactivate and destroy airborne contaminants. Contact us today for reliable, energy-efficient air purification solutions!

Do Air Purifiers Cool the Room?

air purifier room cooling

Air purifiers don’t contain any cooling mechanisms. They are designed to eliminate harmful particles, gases and microorganisms from the air by pulling contaminated air in, blowing it through filters and/or other purification mechanisms, and releasing the cleaned air out the other side. This process creates air movement, which may result in a mild cooling effect, but it has no ability to change the ambient temperature in the room.

Air movement vs. air cooling

Air purifiers move air through a room, which can produce a cooling effect similar to that of a fan. Moving air feels cooler to us because it speeds up the process of convection—hot air rising and being replaced by cooler air. Think of it like blowing on hot soup—the air around the bowl is heated up by the soup, blown away and replaced by colder air that helps the soup cool down more quickly. Moving air also helps our sweat evaporate more quickly, reducing body heat and making us feel cooler.

It’s important to note that while air purifiers are equipped with a fan, it is designed to pull contaminated air into the device rather than push air out into the room like a regular fan. The air that comes into the purifier slows down as it moves through the filters, meaning that it emerges more slowly at the other end. That means that even a small desk fan will be much more efficient at emitting a fast-moving and cooling air stream than an air purifier.

The difference between air purifiers, air conditioners and dehumidifiers for room cooling

Let’s take a look at these oft-confused household devices and their functions with regard to the ability to cool a room.

Air purifiers

The main purpose of an air purifier is not to cool a room—rather, it is designed to clean the air of impurities and contaminants that could be harmful to human health. Whole house air purifiers are intended to improve indoor air quality in order to promote better sleep, reduce asthma and allergy symptoms, and much more.

There are a few different methods of that these devices use to purify the air. One of the most common is the HEPA filter, made of finely woven mesh that can trap 99.97% of even the most penetrating particles (0.3 microns in size). These filters are considered to be very effective at capturing common irritants such as dust, pollen and pet dander.

Air purifiers equipped with activated carbon filters are considered to be most effective at trapping hazardous fumes and unpleasant smells. The activated carbon chemically attracts gases through a process called adsorption, effectively trapping paint fumes, cigarette smoke and other potentially dangerous odours.

There are also residential UV air purifiers that deactivate and destroy harmful microorganisms such as viruses, bacteria and mold spores. Rather than using a mechanical filter, the UV process involves shining strong rays of light on the moving air stream to attack contaminants on a molecular level.

Air conditioners

Air conditioners are units designed specifically to cool down a room. Warm air from the room is drawn into the device and flows over cold evaporator coils that cool it down. The excess heat is vented outside (usually via a window attachment) and the cool air is released back into the room.

While most air conditioners are equipped with filters, these are nowhere near as effective at trapping contaminants as purpose-built air purifiers. However, if you have central air conditioning, there are coil cleaners that can be installed to sanitize your HVAC system.


Dehumidifiers are designed to reduce the amount of humidity in the air. Like air purifiers, these devices don’t actively cool down the air, but they can influence how cool a room feels. When there is a lot of humidity in the air, it slows down the sweat evaporation process that helps us get rid of excess body heat. Humidity can make the ambient air feel much hotter, which is why weather reports often include the humidex to better express what the temperature will feel like. Dehumidifiers eliminate humidity from the air so that our bodies can release excess body heat more effectively.

As with air conditioners, warm, humid air is drawn into the device and blown over cold evaporator coils, removing the moisture from the air by reverting it to liquid form. The moisture is collected and the air is returned to its original temperature before being released back into the room.

Sanuvox: UV air purifiers for cleaner air

As you can see, each of these devices is designed for a specific purpose. It’s best to select the one that matches your desired function for optimal results. Or, if you prefer, you can use the different devices in conjunction for cleaner, cooler, drier air.

If you’ve determined that an air purifier is indeed what you’re looking for, contact Sanuvox today! We offer a selection of first-rate UV light air purification systems for residential and commercial use. Improve your indoor air quality and breathe easy with Sanuvox!

Do Air Purifiers Dry Out the Air in Your Home?

Dry Air Purifier

Air purifiers don’t contain any mechanisms that remove moisture from the air. They are designed to improve indoor air quality by passing air through filters and/or other purification mechanisms in order to remove harmful particles, gases and microorganisms. There are other appliances called humidifiers and dehumidifiers that are made to help control moisture levels in the home.

Why does the air feel dry with an air purifier running?

Whole house or large room air purifiers continually circulate the air in a room. A fan is used to draw air into the device and push it through the filters, removing impurities. Moving air feels cooler because it speeds up the process of convection, allowing hot air to rise and colder air to take its place. Since hot air is able to hold more moisture than cold, it’s easy to associate cool, moving air with dryness.

If the air in your home feels dry, look beyond your air purifier for the source. Indoor air tends to be a lot drier in winter, due to a combination of cold outdoor air that is less able to retain humidity, poor insulation, and central heating that increases the temperature without adding any moisture. These conditions are more likely to be the culprits of dry air in the home.

The functions of air purifiers, dehumidifiers and humidifiers

Air purifiers

The purpose of an air purifier is to cleanse the air in a room. Indoor air can contain all sorts of contaminants, from pollen that gets tracked in from outdoors to the dust that accumulates naturally in every house. These can be detrimental to our health, particularly for those with allergies, asthma and other respiratory problems. Residential air purifiers are designed to eliminate pollutants and improve the quality of the air we breathe.

There are several different types of air purification systems. HEPA filters are mechanical filtration systems that are effective at trapping particles like pet dander. Activated carbon filters, meanwhile, use a process called adsorption to attract and trap harmful gases and odours like cigarette smoke smell. There are also UVC air purifiers that use light to deactivate and destroy microorganisms such as mold spores and viruses.


A dehumidifier is an appliance used to dry out the air in a home. Ambient air is drawn into the device and blown across cold evaporator coils, which reverts the moisture in the air to liquid form. The moisture collects in a water tank and the dehumidified air is released back into the room.

If you have a dehumidifier in the house, you can simply set it to your preferred humidity level (The American Society of Heating, Refrigerating and Air-Conditioning Engineers recommends humidity levels be kept between 30% and 60%). The device will reduce ambient moisture to that level and maintain it. Just remember to empty the water tank regularly!


A humidifier’s function is opposite to that of a dehumidifier—it increases humidity levels in a home rather than decreasing them. Humidifiers are often used in winter to counteract the dryness caused by the cold weather and central heating.

Different types of humidifiers add moisture to the air in a variety of ways. Some boil water and release the steam into the air. Others blow air through a moistened filter or use an ultrasonic frequency or a diffuser to release tiny water droplets into the air.

Air purifiers: an investment in cleaner air

As you can see, air purifiers are designed to clean the air, while humidifiers and dehumidifiers are used to regulate moisture levels. An air purifier won’t have any effect on the humidity in your home, but it will improve air quality.
