What we like
- Smart, Sleep, Eco and Rapid modes, 22 dB at the quietest setting
- 7-year motor warranty and free home installation and service from Coway India
Watch out for
- CADR on cowayindia.in is given as 249 smoke, 261 dust, 230 pollen with no unit; these are AHAM CFM figures, so 423 m3/h is a converted smoke CADR
- Amazon title claims 8,500 hour filter life (1.5 to 2 years) but Coway India's spec table says 1 year
- No app and no numeric PM display, only a colour indicator
- Not listed on Flipkart on 13 Oct 2026
