As houses and apartments get more energy efficient, they also get more airtight, limiting air exchange with the outside world. That’s partly why indoor air is often far more polluted than outdoor air. Synthetic building materials, cleaning products, pet dander, cooking emissions and smoke all conspire to muck up what we breathe in. In our tests, the best way to get the green light from our air quality monitors was opening the windows. But bad weather, wildfires and high pollen-count days mean you can’t always do that. Air purifiers are your next best option. Their combination of specialized filters, fans and sensors suck in particulate matter, VOCs, dust and odors. We tested more than a dozen models to come up with the best air purifier for your home.
