A palm-sized desk purifier with an AHAM-verified CADR. Too small to clean a room: it suits a desk or a bedside table.

We list it because it sells well and because its box claim is the clearest case of the trap: it's a personal purifier, not a room purifier. Keep it next to you on a desk or nightstand. For a whole bedroom, start at the Levoit Core 200S-P.
Too small for any room size we list. Even the smallest, 107 sq ft10 m², needs more air than this purifier moves. Use it as a personal purifier on a desk or bedside table.

A new filter every 6–12 months means 1–2 filters a year. At top speed it draws 7 W: 0.2 kWh if it ran flat out all day. Slower settings use less.

To clean 254 sq ft24 m² it would only change the air in the room 1 time an hour. We size every purifier at 4.8 air changes an hour, the level AHAM's room-size guideline works out to.
Levoit's figure is the room it can change the air of once an hour, and the wording says as much. That's a real number, but at one air change an hour smoke and pollen come back in nearly as fast as the purifier removes them.
