Clean air in your home

In some homes, the presence of indoor air pollutants may actually be two to five times higher than outside air, according to the U.S. Environmental Protection Agency. “You may think that outdoor air is more likely to be polluted than air inside your home, but indoor air is often even more polluted than air outside,” says Payel Gupta, MD, associate clinical professor, specializing in pediatrics and allergy and immunology at Mount Sinai Hospital and SUNY Downstate Medical Center in New York City. This is why it can be beneficial to purchase an air purifier. “Air purifiers can help remove allergens such as pollen, animal dander, mold spores, and other airborne particles from indoor air,” says Dr. Gupta, making the air in your living environment healthier.

Do air purifiers really work?

Air purifiers are especially beneficial for those with allergies or asthma. “As an allergist and asthma specialist, I have advocated purifiers for their usage, as part of an environmental modification initiative, to complement asthma and/or allergy management, for many of my patients,” says Clifford W. Bassett, MD, author of The New Allergy Solution, founder and medical director of Allergy & Asthma Care of New York.

Certain living situations can benefit from air purifiers as well. “This may be particularly important for city dwellers as well as those who reside near busy highways, or a wood-burning stove, where greater levels of particulate air pollutants are a concern,” explains Dr. Bassett.

Individuals living in places with water damage, leaks, known mold exposure, or humidity can also benefit from having a purifier to help clean the air they’re breathing on a daily basis, explains Purvi Parikh, MD, board-certified allergist and immunologist with the Allergy & Asthma Network. “While having a purifier in the bedroom is most important, as we sleep there for hours, any room with water damage, leaks, or one where you spend a lot of time in would be a good place for your purifier to live,” says Dr. Parikh.

What’s the healthiest air purifier?

When purchasing an air purifier, there are a few things you should look for. “Many on market air purifiers often feature a pre-filter, to help to remove larger particles, a HEPA or high-efficiency particulate air filter, which can also remove smaller particles in the air and/or some airborne allergens in your home,” says Dr. Bassett. “Other models may feature additional and newer options such as special filters composed of carbon, to help remove odors, toxins, and chemicals from the air.” Some purifiers also have smart features that allow you to control the device via your smartphone or with the sound of your voice.

“Other certifications to consider when choosing a purifier for your home include Energy Star, Association of Home Appliance Manufacturers, and Allergy Standards Laboratory’s Allergy & Asthma Certified Products,” says Dr. Bassett. “An ideal model should be commensurate with the size and dimension of the room where it is placed. Look at the manufacturer’s estimated costs of running an air purifier, including frequency of replacement filter changes, as well as its noise level.”

A word about air purification and coronavirus

The biggest question of all at the moment when it comes to air purification—can air purifiers filter out the aerosol droplets that might pass Covid-19? Dr. Gupta explains that there is currently no scientific evidence that air purifiers help when it comes to the coronavirus. “We don’t have evidence to say that and majority is spread person to person through droplets and contact in close quarters, so even with HEPA filter purifiers, still there is significant risk,” agrees Dr. Parikh.

However, that doesn’t mean you shouldn’t consider getting a purifier for your home, as the American Lung Association reports that more than half of the U.S. population lives with or are exposed to unhealthy air. Because there are so many options on the market, we took our allergists’ expert opinions to round up some of the best air purifiers for better quality air. Try any of the below if you’re considering purchasing an air purifier.
