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.

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-.

2) Blue Pure 411 Auto – The Best Air Purifier for Allergies ($100)

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). It is currently the best budget air purifier for allergies, with an S+ in performance ranking.

Blue Pure 411 Auto is the latest model of the Blue family from the well-known Blueair company. The air purifier features a more attractive appearance inspired by Scandinavia’s natural surroundings.

• Particle filter – Instead of using a True HEPA filter, the Blue Pure 411 Auto runs a polypropylene fiber filter to help capture 99.97% 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 moment. Its efficiency is greater than that of a standard True HEPA filter while producing less noise and consuming less energy. The best part is that Blue Pure 411 Auto is offered at the same price as the original Blue Pure 411.

Furthermore, you will have the Smart Sensor, which monitors the indoor air quality in real time. The Blue Pure 411 Auto is a simple device to operate, just press one button and you’re ready to go.

At a CADR rating of 107 Dust/123 Smoke/96 Pollen (cfm), this air purifier has a respectable amount of fan power. It is ideal for use in small and medium rooms, and the Blue Pure 411 Auto’s compact form means it will take up little space in your room.

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.

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

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.

In addition to the standard pre-filter, the Rabbit Air A3 has an extra medium filter (a HEPA-type filter) to remove as many airborne toxins as possible. Even if these contaminants get past the double pre-filters, they will not pass through the Rabbit Air A3’s high-quality True HEPA filter. It has a high efficiency of trapping 99.97% of airborne particles down to 0.3 microns. And, thanks to dual pre-filters, it can last up to 12 to 18 months, which is longer than standard True HEPA filters.

Chemicals, smoking, and ordinary household odors may all be eliminated successfully. If you have severe allergies to your pets or to cigarette smoke, you should pick either the Pet Allergy or Odor Remover Customized Filter, which will work in conjunction with the carbon filter of your Rabbit Air A3.
