- Higher CADR of 380 m3/hr for faster air cleaning matters

Buying Tip
The Coway Airmega 150's activated carbon layer is denser than the Xiaomi's, making it more effective at removing cooking odors and VOCs. If your kitchen is open to your living room (common in Indian apartments), the Coway handles kitchen pollution better despite its lower CADR number.
