A slim smart tower with a verified CADR, an air quality sensor and an app. Cleans a large bedroom or a small living room.
Verdict
Who it's for
The same verified CADR as the Levoit Core 300 in a flatter shape that stands against a wall, with an air quality sensor, auto mode and app control. Levoit prints the honest room size next to the big one on its spec sheet, which we wish more makers did.
Good
- CADR verified by AHAM
- Air quality sensor and auto mode
- App and voice control
- No ionizer
Trade-offs
- Bedroom-sized: not enough for most living rooms
- Box headline is based on one air change an hour

The box vs the maths
The box says 1,066 sq ft99 m². It really cleans 217 sq ft20 m².
To clean 1,066 sq ft99 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 prints two figures and labels both: the 4.8 ACH one matches our maths. The bigger one, which we show as the box claim, is at one air change an hour.
243 m³/h smoke CADR ÷ (4.8 × 2.5 m ceiling) = 20.2 m² = 217.9 sq ft20.2 m²
Use the calculator for your exact room and ceiling, or read how we pick.
Drawn to scale: the box says “Ideal Room Size: 1066 ft2 (1 ACH) / 222 ft2 (4.8 ACH)”, the purifier really cleans 217 sq ft, 4.9 times less.Drawn to scale: the box says “Ideal Room Size: 1066 ft2 (1 ACH) / 222 ft2 (4.8 ACH)”, the purifier really cleans 20 m², 4.9 times less.
Room sizes
Which rooms it fits
It suits 107 sq ft10 m² and 161 sq ft15 m² rooms best: there it has 33–100% more air than the room needs, so it needn't run flat out. At 215 sq ft20 m² it only just keeps up (no air to spare), so it would run near its top speed, usually its loudest (why we don’t list noise).
Under a 2.7 m ceiling it covers 201 sq ft, under 3 m 181 sq ftUnder a 2.7 m ceiling it covers 18 m², under 3 m 16 m², so with a 3 m ceiling it no longer covers 215 sq ft20 m² (why).
For a 269 sq ft room or bigger it's too small, although the box claims 1,066 sq ft: the For a 25 m² room or bigger it's too small, although the box claims 99 m²: the 269 sq ft25 m² page lists models that cover it.
