The best air purifier under $400 in 2026
23 models ranked by the maker’s own specs and owner ratings, with today’s prices from 5 stores that ship to the United States.
Up to this budget cost the strongest purifiers of 2026: enough clean air delivery for an open-plan space, quiet at the speed you use most, sensors for gases as well as particles, and sometimes a heater, fan or humidifier in the same unit. Whether that last money is worth it depends mostly on the size of the room. What costs less is on the pages of the lower budgets.
The list below changes daily with the prices. The order is our score from the maker’s measured facts and store ratings. The price is today’s lowest including shipping. What its filters cost a year is on each model’s page.
