Best Air Purifiers in 2020

Reasonably priced and great-looking, the Coway Mighty air purifier is the best for most people. It's perfect for most living rooms and bedrooms and performs well, diminishing airborne particles rapidly with a four-stage filtration system that includes a HEPA filter. Its air quality indicator also lets you know how your air is doing in real time.

Rated for rooms between 400 and 600 square feet, this one's ideal for large living rooms, and perfect if you have high ceilings since it creates a 360-degree airflow. With a three-part filtration system that includes a carbon filter, Blueair claims that this purifier can help remove up to 99 percent of airborne allergens, odors, and other pollutants. The washable pre-filter comes in different colors to match your decor.

The Winix 5500-2 is the perfect combination of quality and price, since it can almost keep up with our top pick, the Coway Mighty, and you can usually find it for under $160. It has a washable carbon filter, as well as a HEPA filter, helping to trap nearly all airborne pollutants as small as 3 microns. It's rated for a 360-square-foot room, so it's great for smaller houses and bedrooms.

Dyson's Pure Hot + Cool Link is an excellent air purifier, but it also pulls triple dude as a cooling and heating fan. It's Wi-Fi-enabled and controllable from the Dyson Link app, which also provides real-time air quality readings, and it features a sleep time, night-mode, as well as an automatic mode, so you can set it and forget it.

If price is your main concern, then check out Koios' $40 purifier, which features a true HEPA filter in its multi-phase filtration system. This purifier is ideal for smaller rooms or as a desk air purifier, and it has a two-speed fan. Its replacement filters are somewhat expensive but do last around eight months.
