Best October Prime Day air purifier & air quality monitor deals

You can’t see most airborne pollutants, but you’ll feel their ill effect on your health over time. Fortunately, Amazon Prime Day is the ideal time to find great deals on air purifiers that remove dust, smoke, mold spores, and other nasty dust that you don’t want in your lungs. A good air quality monitor, meanwhile, will tell you which rooms need the most cleaning and when you should run the purifier.

We’ve spotted some great deals on products from Blueair, Coway, Dyson, Levoit, Shark, and other top brands and listed them below. We’ve organized the list according to the manufacturers’ room-size claims, and we’ve identified which units are “smart,” meaning they can connect to Wi-Fi and be managed with an app. We’ll update this story with new deals as we find them, and we’ll indicate any deals that have ended or changed significantly.
