Decision guide

Which one should you buy?

Pick the one that matches your priorities, not the spec sheet.

Choose

Coway Airmega 150

If you want

  • You want app control, Alexa/Google integration, and smart automation
  • Higher CADR of 380 m3/hr for faster air cleaning matters
  • You want an OLED display with real-time air quality data
  • You use other Mi ecosystem devices for a connected smart home

Choose

Xiaomi Air Purifier 3H

If you want

  • 4-stage filtration with washable pre-filter appeals to you
  • You prefer a simpler device without app dependencies
  • Cooking odor removal is a priority (better activated carbon layer)
  • You trust the Coway brand's global reputation for air purifiers

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.
