Coway Airmega AP-1512HH Mighty vs Levoit Core 300
The Coway moves about 60% more clean air (233 against 143 cfm smoke CADR), enough for a living room of about 34 m² where the Levoit suits a 21 m² bedroom.
The Coway also has a sensor and auto mode. The Core 300 costs well under half the Coway's list price, and for one bedroom it's all you need.
