Top Air Purifier Picks
View all
Whether you worry about everyday dust and pollen or more serious pollutants like smog, mold, wildfire smoke, viruses, or bacteria, an air purifier is a worthwhile investment. That range of concerns might sound broad, but many of these pollutants have something in common: they travel through the air as particles. Larger irritants like dust, pollen, and mold spores, as well as much smaller particles from smoke, smog, and respiratory aerosols, can all be captured by a purifier as it cycles air through an effective filter.
The best air purifiers come with a HEPA-grade filter, since these are designed to capture a high percentage of fine airborne particles. You should also consider a model with an activated carbon filter if odors, smoke, or VOCs are a concern. There are a few other considerations when shopping as well. You want a model that cleans the air efficiently for the size of your space, without creating excessive noise if you plan to run it throughout the day or overnight. Depending on your needs, features like smart sensors, app connectivity, washable filters, or lower long-term maintenance costs may also be worth considering.
