Best Air Purifiers for Asthma List

Rabbit Air Minus A2 - The Best Air Purifier for Asthma

1. Rabbit Air MinusA2 Air Purifier

Out of all of the air purifiers on the market, this is the best one you can get for controlling asthma attacks and allergies in medium to large size rooms.

Air Purifier for Asthma Buying Guide

If you’re looking for more information about air purifiers and asthma, then this section can help.

Below, you’ll find answers to common questions people have about air purifiers for asthmatics, asthma patients, and allergy sufferers as well as some common terms and definitions on air cleaner for asthma machines.

The purpose of this part of the buying guide is to help assist you in making the best choice for an air purifier for asthma and allergies to get relief from your symptoms.

Do Air Purifiers Help with Asthma?

According to research, air purifiers do help asthma. An air purifier can be an effective device for helping relieve asthma symptoms in adults and children. This study indicates that HEPA air purifiers can reduce indoor particulate matter concentrations by approximately 25% to 50% which can help reduce asthma symptoms and exacerbations.

We have an article dedicated to this topic here: do air purifiers help with asthma. It explains more about how well an air cleaner can help by measuring the airflow rate, choosing the right air filter, unit location, and more.

How Does an Air Purifier for Asthma Help?

Best air purifier for asthma and allergies

What makes an air purifier good for asthma is the fact that it strips the air of any particles that cause your symptoms to flare up.

By creating clean, fresh air inside your home, you’ll notice an overall improvement in your health.

You’ll be able to breathe easier, get around better, and not have as many sudden asthma attacks.

However, you do need to get a specific type of air cleaner if you want it to work properly. Buying the wrong type can actually make your asthma worse.

The next part of this guide will help you figure out how to choose the best air purifier for asthma patients and allergy sufferers.

Types of Air Purifiers and Air Filters

There are literally dozens of different types of air purifiers on the market and each one uses a variety of air filters to purify the air. This can make it hard for the average person to know what to look for in an air purifier.

However, when you’re shopping for an air purifier for the purpose of asthma and allergy relief, you need to be knowledgeable about these three types:

  • Ionizers (or ionic air purifiers)
  • Electrostatic precipitators
  • HEPA air purifiers

We’ll explain each of these things in detail below so you know how to choose the right air purifier for your needs.

Ionizers

As an asthmatic, you want to STAY AWAY from ionizers.

The short explanation for how does an ionizer work is that it sends out negatively charged ions into the air to neutralize airborne particles; however, studies have shown that these ions can make your asthma worse and may induce asthma attacks.

Also, some ionic air purifiers emit a small level of ozone as a by-product which can also worsen asthma.

Electrostatic Precipitators

Electrostatic precipitators are a type of air cleaner that uses electrically charged plates to trap particles.

Room air is drawn into the air purifier with a fan and pollutants that pass through the system are electrically charged so they stick to a set of collector plates (i.e. a metal air filter).

Depending on the size of the room and the air cleaner unit, you may have to clean the metal air filter plates daily or weekly.

Similar to ionizers, some electrostatic precipitators do produce ozone as a by-product, which can be an irritant for those who suffer from asthma. Therefore, our recommendation is to stay away from these types of air purifiers for asthma patients.

HEPA Air Purifiers

What you DO WANT for asthma is an air purifier that uses a HEPA filter.

What is a HEPA air filter exactly? HEPA stands for “High Efficiency Particulate Air” and HEPA air purifiers use a highly dense paper air filter to collect allergens and other particles that irritate your asthma and allergies.

Once those particles are trapped inside the air filter, they cannot recirculate back into the room; this creates the cleanest, freshest air possible for an asthmatic and allergy sufferer.

If you’re interested, you can find out more about the difference between an air ionizer vs air purifier.

Now the best type of HEPA air purifier for asthma is the “True” HEPA version.

A True HEPA (High Efficiency Particulate Air) filter is the only type rated to remove up to 99.97% of particles as small as 0.3 microns in size—standard HEPA filters don’t have this certification and may only capture particles down to 2 microns which is about 500% larger in size.

You often find the lower-grade HEPA filters in an air purifier with a washable filter. So be sure to look. So if you have asthma or allergies, stay safe and look for a True HEPA air purifier (like the ones reviewed on this page). It will reduce the highest number of allergens and asthma triggers for you.

A newer alternative to True HEPA filters is a Photoelectrochemical oxidation (PECO) filter. This is a proprietary technology by Molekule that actually destroys organic matter down to 0.1 microns that pass through the system.

A light shines onto the PECO filter membrane that’s coated with nanoparticles. This light-activated catalytic reaction on the surface of the filter is what breaks down microscopic pollutants.

Technically, a PECO filter is more advanced than a HEPA filter and actually destroys the airborne pollutants; however, this technology is only available through the Molekule air purifier brand. So if you want to use it, then you have to choose a Molekule air purifier for your home.

What is the Best Air Purifier for Asthma?

Best air purifier for asthma

The best air purifier for asthma is the IQAir HealthPro Plus. It has the most efficient HyperHEPA filter available that can capture 99.5% of particles down to 0.003 microns. This air filter for asthma also lasts up to 5 years before a replacement is needed. No other air purifier offers that level of protection.

Another stand out feature of the IQAir HealthPro Plus is the V-5 Cell Gas and Odor filter that removes chemical air pollutants and odor molecules and can irritate asthma and allergies. This air filter lasts up to two years.

And finally, this air purifier can clean the air in a room up to 1,250 square feet, making it unmatched in output and performance.

Do Doctors Recommend Air Purifiers?

Doctors do recommend air purifiers for some patients who have certain medical conditions. Research shows that filtering the air can help remove harmful particles from indoor spaces, particularly allergens, mold spores, and smoke as long as it has an approved HEPA filter.

However, doctors do not recommend air purifiers as the only remedy for respiratory and allergy issues. That’s because even the best air purifier for asthmatics is not a cure-all for environmental conditions, diet, and general health practices.

A doctor will often recommend an air purifier in conjunction with proper home cleaning techniques, avoidance of common triggers, and the use of approved medications. According to WebMD, “Since you spend eight hours in your bedroom every night, this should be the first room in which to locate a room air cleaner. However, you may also spend several hours each day in your kitchen, TV room or office, so you may need a separate room air cleaner for each of these rooms.”

Always consult your doctor for treating any condition and to get the best guidance on do you need an air purifier.

What Air Purifiers Do Allergists Recommend?

Allergists recommended the following air purifiers, all of which are reviewed on this page:

  • Rabbit Air MinusA2 air purifier
  • Bluair 280i air purifier
  • IQAir HealthPro Plus air purifier
  • Honeywell HPA250 air purifier
  • Levoit Core 300 air purifier
  • Molekule air purifier

You can also look at all of the air purifiers and air filters that are Certified Asthma and Allergy Friendly by the Asthma and Allergy Foundation of America in order to see your entire options.

And if you have an allergist that you see often, then he or she may have specific air cleaner recommendations that are tailored to your needs and lifestyle.

What Size Asthma Air Purifier Should You Get?

An important aspect you should consider buying an air purifier for asthma and allergy relief is that it can purify a space that’s large enough for your needs.

True HEPA air filters come in a variety of sizes and you need to make sure that you get an air cleaner for asthma that’s capable of cleaning the room (or several connected rooms) that you want to use it in.

This function is especially important if you are a severe asthma sufferer or allergies.

For example, if the air purifier you choose can only clean 100 square feet of air, then it won’t do you any good to place it in a room that’s 400 square feet large—the air purifier will fail to clean the air adequately for you.

And not only will this not help with your asthma or allergies, but it would be a waste of money to purchase that device.

On the other hand, an air purifier rated to clean the air in a room to 400 square feet will work great for any room up to this size.

This includes 100-400 square feet.

At the end of the day, it’s always best to choose a more powerful air purifier than one that’s inefficient for the space you want to use it in.

To help you get the right size air cleaner for your needs, we listed the total square footage coverage for each allergy and asthma air purifier on this page.

And if you don’t know the square footage of the room you want to use the air purifier in, just use this simple formula:

  • Width X Length = Total Square Feet (sq. ft.)

Examples:

  • 15′ X 20′ = 300 sq. ft.
  • 26′ X 30′ = 780 sq. ft.
  • 32′ X 35’= 1,120 sq. ft.

Having clean, fresh air without allergens is crucial to keeping allergy and asthma symptoms under control, so be sure to get the right size air purifier for your home.

And if you’re wondering, “how many air purifiers do I need?”, the answer is at least one but preferably two: one unit for your bedroom and the other for the main living area or location your frequent most in your home.

Can Air Purifiers Make Asthma Worse?

Some air purifiers can make asthma worse. If the air purifier produces a type of gas called ozone, then it can irritate your lungs and make your asthma worse. Avoid products labeled as “air ionizers” or “ozone generators” as they are bad for asthmatics.

HEPA air purifiers do not worsen asthma because these devices don’t produce ozone or any other by-products. The best HEPA air purifier for asthma sufferers, like the units reviewed on this page, can help your symptoms improve over the long-term.

In one research study including children, there was a “statistically significant decrease in the frequency of medications used during air purifier operation.” The study suggests that “air purifiers benefit medication burden in children with asthma by reducing particulate matter,” also known as PM2.5. What’s more, is that this research also verifies the claims about are air purifiers good for babies.

Why are Ionizers Bad for Asthma?

Ionizers are bad for asthma because they can generate ozone which is a known lung irritant for asthmatics that causes chest pain, coughing, shortness of breath, and throat irritation. Air ionizers also emit negatively charged ions into the air that can also inflate asthma symptoms.

We go over this topic in-depth in our ionizer and asthma article. We also talk about are air purifiers good in general. So take a look at those pages if you want to learn more about this issue.

Does Air Purifier Help with Breathing?

An air purifier does help with breathing. Air purifiers clean the air in your home so you breathe in fewer particles that could irritate your, nose, throat, and lungs. A HEPA air purifier is the best type for better breathing because it can remove 99.97% of particles down to 0.3 microns.

There are many advantages of air purifiers, including better indoor air quality to breathe, fewer odors, less dust and dust mites, etc. If you want to learn more about what does an air purifier do to improve breathing, check out the linked articles.

Which is Better for Asthma Humidifier or Air Purifier?

An air purifier is better for asthma. Air purifiers remove particles from the air that trigger asthma symptoms. Humidifiers add moisture to the air and do not have any capability to reduce airborne allergens or other pollutants. Therefore, an air purifier is best for asthma symptoms.

The humidifier vs air purifier questions is a popular one for asthmatics. Hopefully this short answer solves your concerns.

Is Dyson Air Purifier Good for Asthma?

Many Dyson air purifiers are certified as Asthma and Allergy Friendly by the Asthma and Allergy Foundation of America (AAFA). The approved Dyson air purifiers with a HEPA filter are good for asthma.

One thing to keep in mind; however, is that Dyson air purifiers are expensive compare to other good asthma air purifier brands. The average price for a Dyson air cleaner is $400 to $600 dollars and it only covers a room size between 300 to 400 square feet.

In our expert opinion, there are more efficient air purifiers that cost less for asthmatics to use inside their homes that offer equal or better air filtration. Those recommendations are reviewed on this page.

Where Should I Place My Asthma Air Purifier?

Air purifiers only work in the room (or area) that they’re placed in. Therefore, it’s best for an asthmatic to put an air cleaner in their bedroom, where we spend 6-8 hours a night, and in the main living area of the home, where contaminants tend to collect the most.

The best location inside a room is 24 inches from a wall and as close to the center of the room as possible for the most airflow.

What Helps Asthma at Home?

There are several things that can help asthma at home, including an air purifier to remove airborne triggers, drinking caffeinated tea or coffee to open up the airways, rubbing mustard seed oil on your chest and breathing it in, sitting upright, taking slow and deep breaths to prevent hyperventilation.

When Should You Seek Medical Help for Asthma?

While home remedies and an air purifier are great tools to help control your asthma at home, the truth is that these devices can only do so much to prevent or alleviate the problem.

There are still times in which you may have a serious asthma attack or difficulty breathing that requires to you seek emergency medical attention.

If any of the following symptoms occur, you should go immediately to the emergency room:

  • Experiencing severe wheezing or breathlessness that won’t let up.
  • Inability to speak full sentences because of shortness of breath.
  • Having to strain your chest muscles in order to breathe.
  • Asthma symptoms not settling after you’ve uses a rescue inhaler.

Common Air Purifier Terms and Definitions

When you’re shopping for an air purifier, you’ll undoubtedly come across a number of special terms that relate to the air cleaning technologies. While these words may sound foreign to you, their concepts are not that tough to understand.

Below, are the top terms and definitions you may come across when comparing air purifiers for asthma.

Pre-filter: This is a thin layer of protection that acts as the first line of defense during the air purification process. An air purifier pre-filter traps the largest airborne particles as well as dirt and hair. This important function helps to prolong the life of the other internal filters. Most pre-filters last forever and are washable and reusable.

True HEPA Filter: This term was mentioned previously, but in short, it’s the highest standard air filter you can get for an air purifier. To carry the “True” HEPA label, the air filter must meet the strict guidelines of capturing at least 99.97% of particles as small as 0.3 microns in size. These filters are not permanent and must be replaced when they fill up with too many particles.

BioGS HEPA Filter: Rabbit Air’s special type of True HEPA filter. It’s designed in a way that allows the filter to last up to two years which is much longer than the standard True HEPA filters that need to be replaced every six to eight months.

HyperHEPA Filter: IQAir’s version of a True HEPA filter. It captures 99.95% of particles down to 0.003 microns which are 10X smaller than a virus; the smallest that exists. It’s the top performing air filter for removing allergens of all kinds.

Activated Carbon Filter: This filter is specially designed to remove particles that produce odors inside the home. It works by adsorbing the molecules into the filter medium and trapping them there. A carbon filter is also good for reducing volatile organic compounds which can also trigger asthma symptoms. We explain this concept more in our guide on do air purifiers help with smells.

V5 Cell Gas & Odor Filter: IQAir’s patented filter that eliminates gas and odors by combining two types of media. The first media adsorbs odors and gases while the second changes the pollutants to an oxidized form. The V in “V5” refers to the V-shaped media chambers that allow for higher airflow than comparable units.

Ionizer: Another term that was mentioned earlier in this guide, but in short, this type of air cleaner doesn’t use filters to reduce airborne pollutants. Instead, it emits negatively charged ions into the air that latch onto particles to weigh them down. This causes the contaminants to fall out of the air and land on surrounding surfaces. But are ionizers safe? Negative ions can irritate asthma and some ionizers emit ozone as a by-product which also creates problems for asthmatics.

PECO: A proprietary technology by Molekule that eliminates indoor pollutants at a molecular scale. A light shines onto a filter membrane coated with proprietary nanoparticles. This light-activated catalytic reaction on the surface of the filter breaks contaminants apart at the molecular level. Molekule makes one of the best air purifiers for allergies and asthma.

Ultraviolet UV-C Light: This technology kills airborne bacteria and viruses by destroying the DNA structure. Air passes by the UV-C light on its way out of the air purifier. A UV light air purifier is not necessarily good or bad for asthma, but it can help sterilize your indoor environment so fewer illnesses are spread.

Air Changes Per Hour (ACH Rating): This is a specification that tells you how many times an air purifier can exchange the air inside a room every hour. The higher the number, the more efficient the device is at creating clean, fresh air.

Clean Air Delivery Rate (CADR Rating): This is a specification that tells you how well an air purifier can remove certain types of contaminants inside a room (tobacco, dust, and pollen). Only air cleaners that have been independently tested by the Association of Home Appliance Manufacturers (or AHAM) will include CADR numbers. An air purifier CADR rating can help you compare the efficiency between two or more similar air cleaners.

Why Our Homes Can Actually Make Asthma Worse

Did you know that more than 300 million people throughout the world suffer from asthma?

Or, that an average of 10 Americans die each day (about 4,000 per year) from an asthma-related disease?

What about the fact that the air quality inside our homes is 2-5x worse than outside, according to the U.S. Environmental Protection Agency?

These statistics can sound scary, especially for asthma sufferers, but we assure you that there’s hope right around the corner by using a quality air purifier.

While no one knows for sure what causes asthma, nor do we have an actual cure for it, we do know some of the reasons why it’s getting worse for people at home.

The major issue is that indoor air quality is in a steady decline.

Many years ago, when houses and buildings were being built, there wasn’t as much focus on making every nook and cranny a super tight seal.

Unfortunately, structural designs have changed and this has created a new problem, especially for people with asthma.

Now, when new houses are constructed, there’s so much emphasis on making them energy efficient for homeowners. That way, we can use as little air conditioning or heating possible while still maintaining a pleasant temperature.

That efficiency is achieved by creating a tight seal throughout every part of the home.

Another issue is that a lot of people don’t like to open their windows anymore. With the number of people who suffer from allergies increasing each year, this makes perfect sense—they’re trying to protect themselves from outdoor allergens.

Now, you may be wondering, ‘How does a tight seal in my home create problems for my asthma?’

What happens with an airtight seal in your home is that harmful contaminants don’t have a way to freely escape.

Once they’ve been tracked inside from the outdoors (through your clothing or by floating in when a door or window is opened) these particles get stuck and can’t get out.

That build up of pollutants results in many homes becoming infested with asthma-inducing particles that continue to cycle in and out of your lungs.

Fortunately, there’s a solution to all of this—adding an asthma air purifier to your home and the products reviewed on this page are your top options for improving health.

Additional Tips for Helping with Asthma at Home

While choosing the best air purifier for allergies is a great way to remove airborne triggers that cause asthma, there are some additional steps you can take to cut down on the presence of these particles inside your home.

Combining these tips with your air purifier can help you get the most relief for your asthma symptoms.

  • Vacuum at least once per week. All sorts of particles can be tracked indoors on your clothing and shoes. Therefore, it’s a good idea to vacuum regularly in order to remove these contaminants from the indoor space. Like with air purifiers, you can also get a vacuum cleaner that includes a True HEPA filter. That way it will collect the finest particles possible so they don’t end up in the air you breathe.
  • Change your HVAC filters regularly. Home heating and cooling systems use air filters to trap dust, dirt, and hair from damaging the system. The recommended interval for changing these filters is every 3 months, however, if you have severe asthma or allergies then replacing them once per month may be more helpful for you.
  • Minimize the presence of smoke. If you have asthma, reducing the use of candles, incense, and wood burning fires can help cut down on smoke particles that can irritate your lungs. Also, preventing the use of tobacco products indoors is also advisable.
  • Use your home exhaust fans. You can eliminate a lot of asthma triggers that are kicked up into the air while cooking by turning on the stove exhaust fan. If you don’t have one of these, opening the nearest window can also help. This same advice applies to the bathroom during and after a shower, however, the purpose of the exhaust fan in this location is to extract moisture that can irritate asthma and cut down on the production of mold spores.
  • Don’t store paints or chemicals indoors. Although you may have your paints, cleaning chemicals, and pesticides stored inside containers, they can still release volatile organic compounds into the air which can irritate your respiratory system. Therefore, it’s best to keep these products stored outside or in a garage or basement area that’s far away from your breathing area. For areas where this is not possible, consider getting one of the best chemical air purifier units to clean the air of these toxins.
  • Reduce your exposure to pet allergens. If you have pets, a good pet dander air purifier can help remove the airborne dander particles that cause asthma and allergies to flare. (Find out more here: do air purifiers help with pet dander.) However, to ensure long-term relief, it’s best to keep your animals out of the rooms where you spend the most time like a bedroom or living room. It’s also a good idea to bathe or change clothes after playing with pets, or at the very least, wash your hands to remove any pet dander particles.
