Best air purifier in 2020

  • The Blueair Blue Pure 211+ Air Purifier is the best air purifier overall because it can clean a 650-square-foot room in 15 minutes, has an indicator that lets you know when to clean or replace the filters, and complements any decor.
  • We tested and researched more than 10 air purifiers from a wide spectrum of brands to determine the best ones for your needs and budget.
  • Our guide features air purifiers that are easy to maintain, remove a broad array of irritants from the air, and performed well in our tests.

Intense wildfires raging in California and Oregon have burned more than 3 million acres, displaced hundreds of thousands of people, and blanketed cities hundreds of miles away from the epicenters in ash and eerie orange skies. Between wildfires and the novel coronavirus, air quality is at the forefront of many minds. 

An air purifier is a useful appliance that can greatly help improve the quality of indoor air. According to the EPA, air purifiers outfitted with a HEPA filter are an effective way to remove particles from smoke and ash, and can be particularly helpful in improving symptoms for individuals with asthma or COPD that are triggered by wildfire smoke.

If you’re considering an air purifier to help protect against the novel coronavirus, according to the EPA, a portable air cleaner by itself is not enough. However, when used along with other best practices recommended by the Centers for Disease Control and Prevention such as hand washing and social distancing, operating an air cleaner can be part of a plan to protect you and your household. 

Our guide of the best air purifiers recommends models that are easy to maintain, remove a broad array of irritants from the air, and performed well in our tests. When we examined each model, we considered its Clean Air Delivery Rate (CADR), noise level, long-term costs, maintenance, and filtration systems. We also noted how easy they are to use, as well as any other useful features.

We explain our testing methodology more at the end of our guide, and included other models we looked at that didn’t make the cut as well as air-purifying techniques.
