Levoit Core 400S Review
Olivia's rating
Approx. $219.99
Best mid-size air purifier — quiet, app-controlled and quick to clear a living room.
How it scored
What we liked
- +Strong CADR for the price
- +Very quiet on auto
- +Reliable air-quality sensor
What could be better
- –Replacement filters add up
- –No physical air-quality readout
The Core 400S cleared smoke and cooking odours from a 400-sq-ft room faster than rivals at its price, and it's whisper-quiet on auto. The app and air-quality sensor actually work.

- ✓Logged dock behaviour, noise level and weekly maintenance over three weeks.
