How to choose an air purifier
Match it to your room
Every purifier lists the room size it covers (in sq ft) and its CADR, the amount of clean air it delivers per hour. Pick one rated for a room a little larger than yours: it can then clean the air faster on a lower, quieter setting.
Look for a true HEPA filter
A HEPA filter (H13 is common) catches fine dust and PM2.5 particles. An activated-carbon layer helps with smells and smoke. Avoid models that rely only on an ioniser, which can give off ozone.
Check the filter cost before you buy
Filters usually need changing every 6–12 months, depending on use and air quality. Look up the replacement filter price for the model you like: a cheap purifier with costly filters can end up more expensive.
Noise and extras
If it will run in a bedroom, check the noise level on the sleep setting (lower dB is quieter). An AQI display, auto mode and app control are handy but not essential.
Prices are checked on Amazon.in several times a day. Prices and availability can change at any time, so the price on Amazon at checkout is the one that applies.
What does “Limited time deal” mean?
It is Amazon's own deal badge: the discount runs for a short period or until a set quantity is sold.
Which size should I buy?
Choose a purifier rated for at least your room's area. For open-plan spaces or large living rooms, pick a higher CADR rather than a bigger brand name.
