Asthma attacks are no joke, and millions of people suffer from them every year. Asthma is often caused by an overreaction of your immune system to particles of pollen, dander, dust, and other “allergens.” While other things can trigger asthma attacks, such as vigorous exercise, many struggle to get a good night’s sleep or enjoy a day at home thanks to allergens in their living spaces. Air purifiers, however, can bring asthma sufferers peace at home.
How Do You Know an Air Purifier is Good for Asthma?
First and foremost, pay attention to previous buyer feedback. This will tell you if an air purifier actually works against allergens, if it fights odors, and what you can expect from customer service. Look for purifiers with HEPA filters, because they filter the smallest particles out of your air with the greatest efficiency. Multi-stage filtration not only extends the life of expensive replaceable filters, it also helps catch the most contaminants. Quiet motors and Energy Star certification will help you run your air purifier longer. Even though they don’t directly combat asthma, these last two features can help you get the most out of your unit.
We’ve compiled a list of the very best air purifiers for asthma sufferers. These units have different prices and features, but we’ve included both feature summaries and customer sentiment to help you make your decision. If you’re in a rush, check out the pros and cons lists beneath each product review.

Anti-Asthma Air Purifiers…
Alen BreatheSmart HEPA Air Purifier
The Alen BreatheSmart is available in five different colors on Amazon.com. It boasts an 1100 square foot area coverage, as well as a Lifetime Limited Warranty.
While many air purifiers are limited to small living spaces and bedrooms, the Alen BreatheSmart can handle open concept rooms and large living spaces. It can purify the air for rooms up to 1100 square feet. Highly customizable, the BreatheSmart allows users to not only change its outward appearance to match their décor, but also the type of filter within. This allows asthmatics to filter by season. It’s easy to pick filters that remove pollen, dander, and dust. The SmartSensor keeps track of the room’s air quality, so your air purifier can work harder to handle spikes of pollen in the early morning that may trigger asthma attacks, and it will automatically slow when it isn’t needed. This saves power. Speaking of savings, the BreatheSmart is Energy Star certified. This product comes with a 60-day guarantee to ensure it meets customers’ needs.
Customers with allergies and asthma find this product to be one of the most effective they’d ever used. One previous buyer even praised it over a central air conditioning filter, which didn’t remove dander even half so well. Some users left feedback after trying the product for six months or more, and they claimed it continued to perform well after an extended period. One previous buyer did state that their unit began squeaking after a while, but it’s unclear if this was a one-off manufacturing error, since the sentiment isn’t echoed by other users.
- Interchangeable filters for maximum performance
- SmartSensor responds to air quality automatically
- Energy Star certified
- Can handle large, open living spaces
- Very effective against allergens
- May squeak after extended use
Rabbit Air BioGS 2.0
The Rabbit Air BioGS provides allergy sufferers with a holistic approach to air purification. With a smaller light display and a back-end air outlet, Rabbit Air aims to reduce both light and noise pollution while scrubbing your home’s air.
This air purifier can handle rooms up to 550 square feet. While it may not be suitable for large, open living spaces, it can clean the air in bedrooms and studies very effectively. This purifier has four stages of filtration, including a washable pre-filter that extends the life of the interior carbon and HEPA filters. With the pre-filter, the carbon and HEPA filters can last up to three years. As the name suggests, this air purifier has a quiet motor with five available speeds for optimal noise management. The Rabbit Air has a five-year warranty and Energy Star certification.
Many users praised the Rabbit Air’s excellent performance. They compared it to previous air purifiers that caused noise problems, did not effectively clean the air, or failed to circulate the air. The Rabbit Air won buyers over on all these points, and allergy sufferers saw notable improvement in their symptoms. Although one user claimed the unit didn’t remove the smell of a neighbor’s cigarette smoke, the vast majority of users preferred this product over its more expensive competitors.
- Very effective against airborne allergens
- Very quiet
- Multi-stage filtration
- Pre-filter extends the life of expensive disposable filters

Whirlpool Whispure Air Purifier Review
This air purifier offers a three-stage filtration system, beginning with a pre-filter, and ending with a true HEPA filter.
Although it can only filter up to 500 square foot spaces, the Whispure can circulate a room’s air more than four times per hour. The unit includes a pre-filter, a carbon filter, and a true HEPA filter. The pre-filter catches large particles, the carbon filter catches odors, and the HEPA filter can catch particles .3 microns or larger. It has four fan speeds along with sleep and turbo modes.
Buyers with allergy and asthma problems praised the Whispure’s effectiveness about dander, pollen, and other allergens. Although at least one user said the unit was overpriced, they still praised its performance. However, a number of customers complained about the unit’s noise, which was notable even on low settings. According to feedback, the manufacturer’s customer service is also lacking, which may make it difficult to address faulty products and damages.
- Lowest priced air purifier on our list
- Very effective against allergens
- Multi-stage filtration
- Pre-filter protects disposable filters
- Loud operation
- Poor customer service compared to others listed
Every person is different, and it’s a good idea to confer with your doctor before investing in an air purifier. Your doctor may be able to point out specific allergens that trigger your asthma, and you’ll be able to shop as an informed buyer. In general, however, the Alen BreatheSmart appears to be the best air purifier on our list. Not only can it handle the largest area, but its changeable filters ensure you can always target your specific asthma triggers. It is also, however, the most expensive. The second best option is definitely the Rabbit Air, which has the advantage of noise control and a better pre-filter over the Whispure.
