Mi Air Purifier 3 Review

The Mi Air Purifier 3 is the air purifier we recommend to anyone who says they cannot afford to spend Rs 15,000+ on clean air.

At Rs 8,000-10,000 during sale periods, it crosses a psychological threshold that makes air purification a realistic purchase for middle-class Indian families rather than a luxury item. We need to be clear about what you get and what you give up at this price. The 350 m3/h CADR is adequate for rooms up to 400 sq ft, which covers most Indian bedrooms and smaller living rooms comfortably.

In our test bedroom in Pune (roughly 200 sq ft), it brought AQI from 90 to under 25 in about 12 minutes - perfectly acceptable performance. The H13 HEPA filter is genuine, not the H11 or H12 downgrades some budget brands sneak in. The 4.8 kg weight is a genuine practical advantage that reviewers underestimate. In a typical Indian household, the bedroom needs purification at night and the living room needs it during the day.

Rather than buying two purifiers, you carry this one between rooms with one hand. We did this daily for three months, and it never felt like a chore. Smart features via the Mi Home app work exactly like the pricier Xiaomi 4 - same interface, same Alexa and Google integration. The OLED display shows real-time PM2.5, which is motivating and reassuring.

Where the Mi 3 falls short compared to the Xiaomi 4 is carbon filtration - the smaller activated carbon layer handles basic odors but struggles with heavy Indian cooking smells like deep-frying or strong tadka. Filter replacement costs roughly Rs 2,000-2,800 every 6 months in polluted cities, adding Rs 4,000-5,600 annually. Power consumption at 33W is identical to the Xiaomi 4, keeping electricity costs at Rs 150-200 monthly.

If you are debating between this and the Xiaomi 4, the extra Rs 3,000-5,000 for the newer model buys you better carbon filtration and the ionizer.

But if budget is tight, the Mi 3 delivers 80% of the performance at 60% of the price.
