Yearly running cost
We could not confirm the maker's own filter price on 13 Oct 2026, so we do not give a yearly cost. Filter Club (₹999 a year) reminds you when it is due, arranges the genuine filter and fits it.
Which rooms it suits
By our sizing rule (room area x 0.0929 x 2.75 m ceiling x 4.8 air changes an hour), the maker's CADR of 230 m3/h suits a room of up to about 185 sq ft. A 12 by 12 ft bedroom is 144 sq ft and needs 177 m3/h.
Goes well with
₹799 with any other Purispira order. Sealed rooms need airing: 10 minutes every afternoon and before bed. Never use an angithi, coal, kerosene or gas heater in a sealed room.

What we like
- PM2.5 sensor with auto mode, Xiaomi Home app, Alexa and Google voice control
- 20 dB sleep mode
- 27 W max power, brushless DC motor
Watch out for
- New in India (launched Aug to Sept 2026), so little long-term track record
- Genuine replacement filter not yet listed on Amazon.in or found on mi.com; air quality shows as a colour light, not a number; 1 year warranty
