The best air purifier under $150 in 2026
10 models ranked by the maker’s own specs and owner ratings, with today’s prices from 3 stores that ship to the United States.
One step up, in 2026, many purifiers have an air quality sensor with an automatic mode, a night mode that stays quiet and enough clean air delivery for a medium room. Much of the choice is here. What you usually miss: an app, a thicker carbon filter against smells and the power for a large living room.
The list below changes daily: a model that drops just under the limit today because of an offer may be gone tomorrow. 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.
