65 Air Purifiers for Rooms Under 200 sq ft, Ranked by Running Cost

← All room sizes

65 ENERGY STAR certified models, from about $5 to $23 a year to run at the US average electricity rate. CADR (PM2.5) is shown for reference — a higher number clears smoke and fine particles faster, independent of running cost. See how we calculate running costs.

Estimated running cost = annual kWh × 18.31¢/kWh (July 2026 US average). Your own rate may be higher or lower — check your bill. ENERGY STAR figures are lab-test results; real-world use varies. This list includes discontinued and not-yet-sold certified models, and some brands are white-label relabels of the same unit.
