Can Air Purifiers Prevent Asthma? Here's What You Need to Know

Do you struggle with asthma? If so, you might already know how difficult it can be to live your daily life when the tiniest of allergens can trigger your asthma.

Constant asthma attacks can further deteriorate your respiratory health, in turn worsening the condition. The best thing you can do is implement ways to reduce asthma-triggering allergens.

Now, when you are outside, you can reduce inhaling allergens by wearing a mask and taking your medicines on time. However, when you are at home, there are several hidden allergens, such as dust particles, dirt, pollen, pet dander, volatile organic compounds (VOCs), and more. These can also trigger your asthma. So, you can invest in a home air purifier to reduce these allergens.

Do Air Purifiers Alleviate the Symptoms of Asthma?

As someone who struggles with asthma, this is a legit question to ask before investing in an air purifier! Although there still needs to be more research, some earlier research supports air purifiers and their important role in reducing asthma.

Asthamatic Attack

  • European Respiratory Journal 2018 52: Suppl. 62, PA1691. This is a study conducted in 2018 on 50 asthma patients compared to a control group. The study investigated the effects of using air purifiers in their bedrooms. Since it has been established that PM2.5 particles are highly responsible for causing asthma attacks, the study focused on the ability of air purifiers to reduce PM2.5 and alleviate asthma symptoms. The preliminary results show that air purifiers were able to reduce the PM2.5 concentration in the bedroom, thus reducing asthma triggers. Although a lot more research needs to be conducted, you can safely invest in air purifiers for your home to alleviate asthma symptoms.
  • A 2016 review published in The American Academy of Pediatrics also referenced several previously done research in this direction. They concluded that air purifiers with advanced HEPA filters could reduce indoor air pollutants by 25-50%. This can greatly help in reducing asthma symptoms and attacks. However, the review also mentions that air purifiers are unable to remove gaseous pollutants such as nicotine or tobacco smoke.

The Asthma and Allergy Foundation of America (AAFA) also suggests using air purifiers at home to improve indoor air quality and reduce asthma attacks and symptoms.


As you can see, air purifiers can greatly reduce air pollutants in indoor spaces. This can help improve the respiratory health of people struggling with asthma. Although you must take your asthma medications on time, installing air purifiers will definitely improve your health.
