There’s been a load of stunning best air purifiers for allergies and asthma in 2022, yet the Blueair HealthProtect 7770i (and its brother – Blueair HealthProtect 7470i) is certainly the one with the most features. It is not the most expensive air purifier on the market, but for both the performance and the value, it can beat every other device on the market without a doubt.

Top 10 Best Air Purifiers for Allergies and Asthma in 2022

For the performance, this Blueair HealthProtect 7770i packs an unique and signature HEPASilent air filtration system to guarantee the best protection against allergies and asthma.

When you look for an air purifier to solve your health problems (allergies and asthma), you must get the best air filters possible out there. Normally, the HEPA filter is the most efficient air filter being used to capture allergens as small as 0.3 microns. However, Blueair HEPASilent technology can capture particles as small as 0.1 microns in diameter, including viruses, germs, and microplastics, while also eliminating bigger particles such as dust, pollen, smoke, and pet hair. Electrical charging and rapid air movement together may eliminate 99 percent of bacteria.

Moreover, such high efficiency doesn’t require any trade-off. Electrostatic filtration enables the mechanical filtering to be less dense, resulting in an unmatched flow rate of clean air. This also ensures that the Blueair HealthProtect 7770i operates quietly and efficiently compared to other popular air purifiers.

Premium air purifiers have Smart features that make life easier. Advanced sensors monitor coarse particles (PM10) such as dust, pollen, mold spores, and ash, as well as tiny particles (PM2.5 and PM1) such as smoke, viruses, and germs. If pollution levels rise, the Blueair app will monitor the purifier’s work and provide real-time “ETA” updates until the air is pure.

Blueair air purifiers consistently achieve the highest CADR ratings in the world, as recognized and verified by both the AHAM and Energy Star. With a filter efficiency of 400 dust/ 435 smoke/ 435 pollen (cfm), the Blueair HealthProtect 7770i is unquestionably the most efficient air purifier available at this price point.

With the new year comes a new contender for the best air purifier for allergies, the Blue Pure 411 Auto. A high-end HEPASilent air purifier that is rigorously tested and approved by the California Air Resources Board (CARB) and the Association of Home Appliance Manufacturers (AHAM).

best air purifier for allergies

Blue Pure 411 Auto is the latest model of Blue family from the well-known Blueair company. The air purifier now features a more attractive appearance inspired by Scandinavia’s natural surroundings. Moreover, the HEPASilent technology has been updated to a new level, enabling it to catch particles as small as 0.1 microns at a rate of 99 percent.

  • Pre-filter – It’s worth noting that the fabric pre-filter of Blue Pure 411 Auto is outside the air purifier. This is one great advantage of this pre-filter, because you can easily check the status of it to vacuum or wipe the contaminants out immediately.
  • Particle filter – Instead of using a True HEPA filter, Blue Pure 411 Auto runs a polypropylene fibers filter to help capture 99% of all allergens like dust, dust mites, pet dander, pollen and fungi (HEPASilent technology).
  • Activated Carbon Filter – The Activated Carbon filter is added inside the Particle filter and effective against smoke, odors, gases and VOCs.

As indicated previously, HEPASilent is the most sophisticated air filtering technology available at the present. Its efficiency is greater than that of a standard True HEPA filter while producing less noise and consuming less energy. The best aspect is that Blue Pure 411 Auto maintains a pricing point comparable to the original Blue Pure 411.

Furthermore, you receive the Smart Sensor (dust and gas sensors), which monitors the interior air quality in real time. The Blue Pure 411 Auto is an easy device to operate, since you do not have to think about controlling it. Simply press one button and you’re ready to go.

4) Coway AP-1512HH – Still Best Pick on a Budget

 Previously in our list:   Coway AP-1512HH.

As the best affordable gadget from Korea’s No. 1 air purifier brand (Samsung’s home nation), the Coway AP-1512HH can win any conditions to be one of the best air purifiers for allergies and asthma in 2022. Actually, this device is nominated to be the Best Air Purifier not only from Breathe Quality, but also lots of well-known reviewers. Though many years have passed, it seems the Coway AP-1512HH is still the best budget air purifier you can buy right now.

best air purifier for allergies

Coway AP-1512HH received several excellent ratings as “Best Air Purifier” last year due to its 4-stage air purification system. This air purifier has the same performance rating as the powerful Honeywell HPA300, and hence is extremely effective against allergens and asthma triggers.

  • Pre-filter – A washable pre-filter will help you capture the large particles of contaminants, from pet hair, human hair and mold.
  • Activated Carbon Filter – This filter works its best to deodorize and trap harmful gas to keep your place fresh and odor-free.
  • True HEPA filter – The high-performance composite True HEPA Filter that captures 99.97% of down to 0.3 microns allergens, virus particles, pollen, mold and fungi particles.
  • Ionic Technology – Vital ionize can trap even the tiniest airborne particles and send it back to other filters. Can be switched on/off.

First, we’re going to examine this Coway AP-1512HH’s outstanding performance. To begin, its True HEPA filter is identical to that of the Honeywell HPA300, which captures 99.97 percent of allergens, virus particles, pollen, mold, and fungal particles as tiny as 0.3 millimeters. Apart from that, the ionizer is critical to the Coway AP-1512HH’s efficiency. It charges the ions in order to attract and trap pollutants in the True HEPA filter. This combination is frequently seen in high-end devices such as the Rabbit Air MinusA2.

Likewise, the Coway AP-1512HH Deodorization Filter, or Activated Carbon filter, is excellent. It can assist in removing tiny particles, hence extending the life of the True HEPA filter; also, it can absorb the majority of chemicals, smoke, home aromas, and dangerous gases.

With this level of performance, it’s understandable why the Coway AP-1512HH has received several certificates and honors, including the British Allergy Foundation Seal of Approval.

Plus, the sound is quite quiet, if not the quietest for an air purifier. Additionally, the Eco Mode (Coway’s Smart Sensor) ensures that the Coway AP-1512HH always operates at a low level with almost little noise. You may use this air purifier continuously throughout the night to help keep allergies and asthma at bay.

With a great CADR rating of 246 Dust/ 233 Smoke/ 240 Pollen, this Coway AP-1512HH can cover up to 360 square feet.

In our air purifier ranking list, Coway AP-1512HH ranks B+, and if you can get a deal on Coway AP-1512HHS, you should get it instead, which ranks A+.

Here is the pros/cons of Coway AP-1512HH:


  • Amazing performance rating
  • Advanced air filtration process
  • Smart Features like Smart Sensor and Eco Mode
  • Good ACH and CADR

  • The top light can’t be turned off
  • Only has dust sensor

5) Levoit Core 600S – New Best Allergen Remover

 Previously in our list:   Honeywell HPA300.

Levoit Core 600S completely win the position of the best allergen remover from the old Honeywell HPA300, with strong performance for the price, great smart features as well as economical annual cost.

best air purifier for allergies

We know you don’t need a flashy air purifier, but the Levoit Core 600S is truly powerful with its air filtration system.

  • Pre-filter – Using the mesh preliminary filter, Levoit Core 600S is able to capture most of the large objects like dust, hair, lint, fibers and pet fur right at the first stage of its air filtration process.
  • True HEPA filter – Levoit Core 600S uses a H13 True HEPA Filter to reduce 99.97% of as small as 0.3 microns allergens, virus particles, pollen, and bacteria particles.
  • Activated Carbon Filter – The custom high-efficiency Activated Carbon filter (ARC formula) is especially effective for cooking smells and pet odors in a multi-pet household. It also extends the life of the filter by chemically decomposing molecules trapped within the Activated Carbon Filter, which prevents oversaturation and second-hand pollution.

What is the successful formula for a low-range air purifier? 40% of famous companies will reduce fan power, while the remaining 59% will reduce the quality of the air filters or add a cheap UV-C light or ionic filter.

However, what about the final 1%? It will have a powerful fan and one of the most remarkable True HEPA filters available. Is this offer too good to be true? The Levoit Core 600S has an even better fan power than the previous air purifier in this spot.

With an amazing CADR rating of 373 Dust/377 Smoke/437 Pollen (cfm) and 5X ACH, this air purifier will clean your room in a matter of minutes. This fan power is on par with even mid-range budget devices, like the Blueair Classic 405 or the Alen BreatheSmart. Levoit Core 600S is effective in a room of up to 600 square feet.

In our air purifier ranking list, Levoit Core 600S ranks A+.

Here is the pros/cons of Levoit Core 600S:


  • High performance rating True HEPA Filter
  • High fan power
  • High CADR and ACH
  • Smart features

  • Too big

6) Rabbit Air MinusA2 – Last year’s Champion

 Previously in our list:   Rabbit Air MinusA2.

Still on our list of the best air purifiers for allergies in 2022 is the old champion – the Rabbit Air MinusA2. It won’t go out of the list easily, as you can see.

best air purifier for allergies

For the performance, this Rabbit Air MinusA2 packs an unique 6-stage air filtration system to guarantee the best protection against allergies and asthma.

  • Pre-filter & Medium Filter – Double the pre-filtration means double the effectiveness against allergens. These 2-layer filters will guarantee to trap large and medium particles, for example, dust mites, pet hair, large pollen, pet dander, mold and dust particles.
  • Advanced BioGS HEPA Filter – It is a True HEPA Filter that captures 99.97% of all allergens, bacteria, virus particles, pollen, mold and fungi particles down to 0.3 microns. Rabbit Air advances their air filter process, therefore prolong optimal filter efficiency and filter life of their HEPA Filter.
  • Customized Filter – Double the protection with a variety of customized filters for specific needs like Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber. You can tailor the MinusA2 air purifier to fit your personal needs.
  • Activated Carbon Filter – Eliminates household and cooking odors, tobacco smoke and exhaust fumes and VOCs.
  • Ion Generator – Rabbit Air MinusA2 still has ionizer technology to trap even the tiniest particles of pollutant back into other filters. Can be switched on/off.

Expert tips: The amount of ozone is about 0.002 ppm, which is 25 times less than the 0.05 ppm maximum ozone safety standards set by the California Air Resource Board – the authorized air cleaning agency in the government of California.

When shopping for an air purifier to treat your health problems (allergies and asthma), you must consider both the amount and quality of the air filters contained in this device. Generally, the more filters, the more steps there are for removing allergens from the air. A typical air purifier has three or four steps of air cleansing, however the Rabbit Air MinusA2 features six stages and five mechanical layers of air filters.

Regarding the air filters, they are of the high quality that we have come to expect from Rabbit Air. In addition to the standard pre-filter, Rabbit Air MinusA2 has an extra medium filter (a HEPA-type filter) to remove as many airborne toxins as possible. Even if these contaminants get through the double pre-filter, they will not pass through the Rabbit Air MinusA2’s high-quality True HEPA filter. The 99.97 percent efficiency down to 0.3 micrometer particles is the highest ever measured. And, owing to the required assistance provided by these twin pre-filters, it can survive up to 12 to 18 months longer than standard True HEPA filters.

The Rabbit Air MinusA2 Charcoal-Based Activated Carbon Filter is constructed with high-grade granular activated carbon, which outperforms the most common thin layer of activated carbon. Chemicals, smoking, and ordinary household scents may all be eliminated successfully. If you have severe allergies to your pets or to cigarette and cigar smoke, you should pick the Pet Allergy or Odor Remover Customized Filter, which will work in conjunction with the carbon filter in your Rabbit Air MinusA2. With up to double filtration against all sorts of chemicals, smoke, odors, and smells, Rabbit Air MinusA2 ensures that you will no longer suffer from allergies or asthma problems.

There is only one downside, with such low CADR rating as 200 Dust/ 193 Smoke/ 208 Pollen (cfm), the Rabbit Air MinusA2 might take more time to clean your room completely. Particularly for an 815-square-foot room, this air purifier can exchange air only once every 30 minutes, requiring you to wait at least one hour for air cleaning process.

In our air purifier ranking list, Rabbit Air MinusA2 ranks A.

Here is the pros/cons of Rabbit Air MinusA2:


  • Top-notch performance
  • Advanced Air Filtration process
  • Smart Features
  • Ultra Quiet

  • Low CADR in mid-range segment

AIRMEGA 400 maintains the outstanding quality of earlier Coway models while incorporating all air filters into a single Max2 filter for improved performance.

Overall, the AIRMEGA 400 is capable of removing 99.97% of as small as 0.3 microns pollutant particles, and it can deal with even strong odors which can trigger asthma.

Without a doubt, the AIRMEGA 400 functions softly, with a noise level of only 22 dB, which is quieter than the Rabbit Air MinusA2. It is even silent than a whisper, and you can barely hear anything coming from this gadget.

This air purifier has a CADR rating of 340 Dust/350 Smoke/400 Pollen (cfm) and can cover a space of 1560 square feet. The AIRMEGA 400’s increased fan power enables it to clean a room more quickly than our old champion, the Rabbit Air MinusA2.

Finally, with this AIRMEGA 400, we have a fantastic Smart Sensor. Numerous studies have established that its sensor is the most precise and quickest on the market. It will always inform you of the current state of the air quality in your vicinity and adjust the fan speed automatically to compensate.

best air purifier for allergies

Blueair is a household name in the air purifier market, with products accessible in more than 50 countries. It is well-known for producing only one highly effective air filter for their equipment. In this Blueair Classic 680i, you can choose between these air filters.

  • Particle Filter/ SmokeStop Filter – You can choose from the Particle Filter with the power to capture 99.97% of pollutants such as pollen, dust, pet dander, mold spores, viruses and bacteria down to 0.1 microns. Otherwise, you can pay more for SmokeStop Filter, which has one additional layer of Activated Carbon Filter.

Blueair Classic 680i’s Particle filter performs identically to any other True HEPA filter on the market. It combines mechanical and electrostatic filtration to ensure that allergens as small as 0.1 microns do not get through the filter. Additionally, the Blueair Classic 680i’s filter’s gradient structure catches particles of all sizes while preserving maximum airflow. It is impervious to clogging and will not reintroduce particles into the air, even when the filter is fully filled.

To combat against the gases and odors, Blueair Classic 680i uses a SmokeStop filter with highly porous structure made of activated carbon. We spent three months testing the Blueair Classic 680i’s air filter and can confirm that it is naturally antibacterial. Having said that, the air filter will help prevent bacteria and mold development, two of the leading causes of allergies and asthma.

Blueair’s technology is appropriately named HEPASilent. This Blueair Classic 680i runs in a quiet mode with a noise level that is even lower than that of rustling leaves on the ground.

Blueair Classic 680i is a high-end air purifier that can be operated by Alexa. This function is excellent, yet for the majority of allergy and asthma sufferers, the Smart features are often disregarded.

Blueair Classic 680i has a powerful CADR rating of 500 Dust/ 500 Smoke/ 640 Pollen (cfm). With such power, this air purifier is capable of cleaning 775 square feet with no difficulty.

 Previously in our list:   Austin Air HealthMate Plus.

If you suffer from severe allergies or asthma and require only medical-grade air purifiers, you cannot afford to overlook the brand Austin Air. This brand has been a pioneer in the air purifier business for over 15 years, dating all the way back to 1990. They operate the largest air purifier production plant in the world in the United States, with everything made in-house. The Austin Air HealthMate Plus is this company’s air purifier that can recreate the exact “hospital clean room” environment.

best air purifier for allergies

Austin Air HealthMate Plus is designed to effectively remove all types of allergens and asthma triggers with the powerful 4-stage air cleaning system:

  • Pre-filter – To remove any large objects of pollutant particles like pet hair, human hair or large dust. This pre-filter is washable and permanent.
  • Medium Particle Pre-filter – Austin Air HealthMate Plus can remove molds, spores and pollen with this pre-filter.

The Austin Air HealthMate Plus, like the Rabbit Air MinusA2, has a twofold pre-filtration system. The Medium filter is a stand-alone HEPA filter that provides adequate protection against particles of small to medium size such as spores or plant pollen. The True HEPA filter will last up to 5 years longer with these two pre-filters. You’re not convinced? Austin Air delivers the industry’s most complete 5-Year Pro-rated Filter Warranty.

Austin Air HealthMate Plus eliminates 99.97 percent of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns with ease. This level of performance demonstrates the true strength of a Medical-grade True HEPA filter. Additionally, the Austin Air HealthMate Plus features an Activated Carbon filter that is impregnated with potassium iodide and zeolite to eliminate Volatile Organic Compounds (VOCs), formaldehyde, benzenes, chemicals, gases, and smells.
