Before buying during Republic Day sales, focus on the basics. Ideally, choose a purifier with a True HEPA H13 or H14 filter, along with activated carbon for odours and VOCs. Match the CADR to your room size, ideally around two-thirds of the room area in sq.ft. Check noise levels if it’s for a bedroom, as anything under 35 dB is easier to live with, though higher fan speeds will be louder. Always verify the final discounted price, warranty, and annual filter replacement cost. Smart features like auto mode and AQI indicators are useful, but effective filtration should come first. Check sale timings carefully to get the best deal.
