The best water purifiers and air purifiers in India — chosen on your water and your air, not on marketing.

For most Indian homes on groundwater or blended supply, the KENT Grand Plus (around ₹16,499) and Aquaguard Delight NXT (around ₹17,990) are the strongest all-round choices — both handle input TDS up to 2,000 ppm, include a TDS controller, and are backed by the country's best service networks. The AO Smith Z9 Green RO is the best premium option. But if your water tests below 200 ppm TDS, you should buy a UV+UF purifier instead and save both money and water.

The Philips 2000i Series AC2939 (around ₹24,990) is our overall pick — 333 m³/h CADR, true HEPA, a numeric PM2.5 display and affordable, widely available filters. The Xiaomi Smart Air Purifier 4 (around ₹12,999) is the best value at 400 m³/h CADR. For bedrooms, the Levoit Core 300S is the quietest at 24 dB.

For water, measure your TDS with a ₹300 meter: under 200 ppm buy UV+UF, over 300 ppm buy RO+UV, and always buy RO if your area has known arsenic, fluoride or nitrate issues. For air, calculate required CADR as at least 5× your room's floor area in square metres, then size up one class — two in very high-pollution cities. Our free calculators do both.

Yes. We earn affiliate commissions when readers buy through our links and we generate leads for commercial installations, but that never changes our rankings — which is why you will find us recommending a ₹1,449 gravity purifier over a ₹30,000 RO where that is genuinely the right answer, and telling you when premium features are not worth paying for.
