Top 10 Best Air Purifiers for Allergies and Asthma in 2024

1) Blueair HealthProtect 7770i – Quite simply, the best air purifier for allergies and asthma in 2024

There’s been a load of stunning best air purifiers for allergies and asthma in 2024, 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 2024

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

  • Smart Filter – The ultimate Blueair HEPASilent Ultra technology helps remove 99.97% of pollutants such as pollen, dust, pet dander, mold spores, viruses and bacteria down to 0.1 microns. It will destroy the viruses and bacteria instead of trapping them only.

When you look for an air purifier to solve your health problems (allergies and asthma), you must get the best air filters possible. Normally, the HEPA filter is the most efficient air filter used to capture allergens as small as 0.3 microns. However, Blueair’s HEPASilent technology can capture airborne particles as small as 0.1 microns in diameter, including viruses, germs, and bacteria, while also eliminating bigger particles such as dust, pollen, smoke, and pet hair. Electrostatic 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 possible, as recognized and verified by both the Association of Home Appliance Manufacturers (AHAM) and Energy Star. With a CADR rating of 400 Dust/ 435 Smoke/ 435 Pollen (cfm), the Blueair HealthProtect 7770i is unquestionably the most powerful air purifier available at this price point.

Overall, the Blueair HealthProtect 7770i is by far the most complete on the market – you won’t regret your choice if you pick up this air purifier.

In our air purifier ranking list, the Blueair HealthProtect 7770i ranks S-.

Here are the pros/cons of the Blueair HealthProtect 7770i:

PROS


  • Top-notch performance

5) Coway AP-1512HHS – The Best Air Purifier for Allergies ($250)

As the direct upgrade from the most popular air purifier of the Korea’s No. 1 air purifier brand (Samsung’s home nation), the Coway AP-1512HHS can meet any condition to be one of the best air purifiers for allergies and asthma in 2024. Actually, the former device was nominated to be the Best Air Purifier not only by Breathe Quality, but also by lots of well-known reviewers. That’s why it isn’t a surprise to see the upgraded Coway AP-1512HHS as the best air purifier for allergies you can buy right now.

Top 10 Best Air Purifiers for Allergies and Asthma in 2024

Coway AP-1512HHS received several excellent ratings as the “Best Air Purifier” thanks to its new 3-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, such as pet hair, human hair and mold.
  • Activated Carbon Filter – This improved honeycombed carbon filter deodorizes and traps harmful gas to keep your place fresh and odor-free. It reduces more than 90% of Volatile Organic Compounds and fumes such as NH3 and CH3CHO.
  • 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.

First, we’re going to examine this Coway AP-1512HHS’ 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. The new carbon filter is thicker, so it is much more effective than the former one. It can assist in removing small particles, thereby extending the life of the True HEPA filter. Also, it can adsorb the majority of chemicals, smoke, odors, and dangerous gases.

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

Plus, the noise level is really low, so this air purifier is really quiet. Additionally, the Smart Sensor ensures that the Coway AP-1512HH always operates at a low level with almost no noise. You may use this air purifier continuously through the night to keep allergies and asthma at bay.

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

Commonly, to bring down high-end air purifier specs into the low-range segment, most of the air purifier manufacturers need to sacrifice either the fan power or the air filter’s quality. However, Levoit shows us that we can have a high-end air purifier at low cost, still packing with high fan power and H13 True HEPA filter.

With an amazing CADR rating of 373 Dust/377 Smoke/437 Pollen (cfm) and a 4X ACH, this air purifier will clean your room in minutes. This fan power is on par with even mid-range devices, like the Blueair Classic 405 or Alen BreatheSmart Classic.

  • Pre-filter – The Micro-particle filtration is the preliminary elimination of the micro-particles such as pollen, pet dander, and mold spores that is drawn in through the air intake.
  • V5-Cell Gas & Odor filter – Next, you will experience the powerful V5-Cell Gas & Odor filter (exclusively for IQAir air purifiers). With both high quality granular activated carbon adsorption and pelletized chemisorption, this filter will destroy any harmful VOCs and chemicals. Moreover, the average filter life is about 2 years, effectively reducing the cost of filter replacement.
  • True HEPA Filter – IQAir uses an unmatched HyperHEPA filter which can capture 99.97% down to 0.3 microns particles and even 95% of particles down to 0.003 microns.

There should be no more contention over IQAir air purifiers’ world-class performance rating, particularly the flagship IQAir HealthPro Plus. This air purifier incorporates the most advanced strong HyperHEPA filter H13, which outperforms the IQAir GC MultiGas‘s powerful filter H11. It embodies what the majority of air purifier consumers desire: flawless fresh air purification. 

You are well aware that this is a high-priced air purifier, but IQAir has done all it can to justify the price. Even the pre-filter is capable of capturing 55% of particles as tiny as 0.3 microns. It will contribute to the efficiency improvement of the upcoming HyperHEPA filter, which is a non-woven glass microfibre, non-offgassing True HEPA filter capable of filtering out even the tiniest ultra-fine particles. Most significantly, the average filter life of this True HEPA filter is roughly four years, making it without a doubt the world’s greatest HEPA technology to date.

You should now understand why the Swiss company claims that its IQAir HealthPro Plus is the “#1 Rated room air purifier for allergies & asthma.” Additionally, their V5-Cell is an excellent option for dealing with various chemicals, smoke, and smells.

With an impressive CADR rating of 300 cfm and up to 776 cfm, the IQAir HealthPro Plus is a beast for an area of 1125 square feet.

We’ll skip the Smart Sensor introduction because, like many other high-end air purifiers, the IQAir HealthPro Plus lacks an Auto Mode preset. Apart from that, we cannot find anything negative about the IQAir HealthPro Plus, which is an all-in-one solution for allergies and asthma.

In our air purifier ranking list, the IQAIr HealthPro Plus only ranks B-, but we must assure you that its HEPA filter is on par with the Austin Air HealthMate Plus, and they’re the ultimate solution in capturing allergens.

Review: IQAir HealthPro Plus Review.

If you have a problem with smoke, or if the primary trigger for your asthma is anything connected to smoke or smells, you should instead use the IQAir GC MultiGas. Although this air purifier’s HyperHEPA filter is inferior to that of the IQAir HealthPro Plus, it is strong enough to outperform all other True HEPA filters. The bottom line is that its Cartridge-based Activated Carbon filter performs at an unmatched level of excellence. This filter’s ABS plastic construction is of the finest quality and is capable of removing hazardous chemicals, formaldehyde, smoke, smells, and Volatile Organic Compounds (VOCs).
