Mi Air Purifier 3 Review

The Mi Air Purifier 3 delivers genuine H13 HEPA filtration with smart home connectivity at what is arguably the lowest price for a credible air purifier in India at Rs 8,000-10,000. At just 4.8 kg, it is light enough to carry between rooms with one hand, letting you use it in the bedroom at night and the living room during the day. The real-time OLED PM2.5 display and Mi Home app with Alexa and Google Assistant integration bring premium smart features to the most budget-conscious segment.

At Rs 8,000-10,000, it delivers genuine H13 HEPA filtration with 350 m3/h CADR and smart features you would typically find at Rs 20,000+. At just 4.8 kg, you can easily move it between rooms - use it in the bedroom at night and living room during the day.
