The deciding factors

The Xiaomi 4 moves more air than purifiers costing twice as much, shows you a real PM2.5 number, and takes cheap filters. For a first air purifier, or for the second and third rooms once you have decided you want one everywhere, nothing else makes as much sense.

Against that, Philips AC1215 makes its case differently: The AC1215 has been the sensible bedroom recommendation for years and remains so. You get Philips' NanoProtect HEPA, 270 m³/h CADR, 20.5 dB sleep operation and a two-year filter life for under ₹12,000, with a two-year warranty and filters you can buy anywhere.

Our practical advice: unless the Xiaomi Smart Air Purifier 4's specific advantages match a real constraint you have — tank size for long water cuts, a higher TDS rating for brackish supply, hot water you will genuinely use — the cheaper unit is the better purchase. In this category, paying for capability you will never use is the most common way money gets wasted.
