How benchmarksutra rates air purifiers: maker-stated specs and Indian prices only, nothing guessed.
Quick Verdict
The benchmarksutra Air Purifier Score rates 4 air purifiers sold in India. Every spec comes from the maker's own product page, and every price from an Indian retailer's listing. We never use test results from other sites, and we never fill a gap with a guess.
Researched, not hands-on tested. Scores use only the specifications on each maker's own product page (checked 14 November 2026) and prices at Indian retailers (checked 14 November 2026). We did not test these air purifiers ourselves. How the benchmarksutra Air Purifier Score works.
What we rate
Clean air delivery rate. Particle (or smoke) CADR in m³/h exactly as the maker states it: 100 rates 0, 450 or more rates 100. Makers test to different standards (AHAM, GB/T), so treat small gaps as a tie.
Lowest noise level. Lowest (sleep-mode) noise the maker states: 35 dB rates 0, 20 dB or quieter 100. Not stated means the row is left out.
CADR per watt. CADR divided by the maker-stated maximum power: 3 m³/h per watt rates 0, 12 or more rates 100.
Filter life. Main filter life the maker states: 6 months rates 0, 24 months or more 100. Where the maker gives two different figures, the row is left out.
Warranty. Product warranty in years: 1 year rates 0, 3 years 100.
App control. Wi-Fi app control named by the maker: yes 100; not named counts as no.
Price per CADR. Price divided by CADR, against the lowest price per m³/h in the list.
Buyer profiles
What we checked
We read each maker's own product page for CADR (clean air delivery rate), lowest noise level, rated power, filter life, warranty and app control. Retail listings are used only for the price. We use CADR exactly as the maker states it; makers test to different standards, so a gap of 10–20 m³/h is effectively a tie. App control counts as "no" unless named; other missing rows are left out and the weights re-spread. A purifier is ranked only if its maker states at least 4 of the 7 rated specs.
What we do not rate
Real pollutant removal, odour and gas removal, and sensor accuracy need lab tests. We do not run them and we do not use other sites' results. We make no health claims: a purifier cleans the air in one closed room and does not treat any illness. Size it by CADR: about 2 to 3 times your room volume in m³ per hour.
