The best Prime Day air purifier deals

Can air purifiers help with wildfire smoke?

Yes. Wildfire smoke is adversely affecting the air quality in parts of the country. Experts recommend keeping windows shut, staying indoors, running an air purifier with a HEPA filter, and avoiding tasks that can stir up fine particles, like vacuuming. One of the best air conditioners with a good HVAC filter can also supply some relief.

Canadian wildfires have adversely affected the air quality in Michigan, where I live. When I walk outside, it's hazy and smells like smoke. Inside, where I have an LG and a Blueair air purifier running continuously, I can't smell a thing, and the people with asthma in my family have not experienced irritation.

Junfeng Zhang, a professor of global and environmental health at Duke University, recommends choosing an air purifier with a HEPA filter to improve indoor air quality. Your purifier will perform better when you keep your doors and windows closed. Rather than moving air purifiers from room to room, keep them in one spot, allowing continuous air purification and maintaining good air quality in the room. For this reason, you may want to purchase a unit for each room.

The Levoit 300S is a great option for small rooms, and with the Prime Day deal, you can purchase multiple units to improve the air quality in rooms throughout your home. If you want to purify the air in a larger room, consider the Blueair HealthProtect 7470i, which operates quietly and can purify the air in a 513-square-foot room every 15 minutes. Both of these models are top picks in our guide to the best air purifiers.
