How this ranking is scored

We took zero-ozone ENERGY STAR air purifiers certified as connected (app or Wi-Fi capable) and compared the 10 with the highest smoke CADR.

Smoke CADR (60%): how fast the unit removes smoke-sized particles, the hardest test (higher is better)
Smoke CADR per watt (25%): clean air per watt; matters when it runs all day during smoke events (higher is better)
Rated room size (15%): the largest room it is certified to clean (higher is better)

Each number is scored against the best on this page (best = 100%; e.g. 90% of the best capacity = 0.9) and multiplied by its weight; the total is out of 100. Full method.

FAQ

How fast do they clean?

Certified smoke CADR on this page ranges from 366 to 523 cfm.

Do any of these produce ozone?

No. Every model on this page has 0.00 ppb certified ozone emissions.

Where do these numbers come from?
