The reviews
Levoit Core 400S
Lab tests clear a room in 24 to 30 minutes. Dearer now the standard model has sold out.

Levoit Core 300S
App and auto mode for one bedroom. The Vital 100S is now cheaper and bigger.

Levoit Core 600S
The highest lab-tested clean-air rate we rate, with real carbon. Filters are dear.

Xiaomi Air Purifier 6
Lots of clean air for the money; genuine filters only, and a lazy auto mode.
