Xiaomi Xiaomi Smart Air Purifier 4 Lite
The best value-for-coverage purifier you can buy under ₹15,000. A True HEPA filter plus activated carbon traps 99.99% of 0.1-micron particles, smoke and odour, and the front AQI display shows real-time PM2.5 so you actually watch the red number fall. With up to 360 m3/h CADR it clears a 350-450 sq ft living room or large bedroom fast, and runs quiet enough for sleep. Wi-Fi and the Xiaomi Home app let you schedule it and get a filter-replacement reminder so you're never guessing.
