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.

Quick answers
The Xiaomi 3H is better for tech-savvy buyers who want app control, voice assistant support, and real-time monitoring. The Coway Airmega 150 is better for those who prioritize raw filtration quality with its 4-stage system and cheaper filter replacements. For most modern Indian homes, the Xiaomi's smart features tip the balance.
The Coway's washable pre-filter extends main filter life by 2-3 months because it catches large particles first. Typical filter life is 8-10 months for Coway vs 6-8 months for Xiaomi in polluted Indian cities. Coway filters also cost less at Rs 2,500 vs Rs 2,500-3,000 for Xiaomi.
No. The Coway Airmega 150 has basic manual controls, an LED air quality indicator, and a filter replacement light. There is no app, no WiFi, no voice control. If smart features matter, the Xiaomi 3H is the only choice at this price.
