Buying Guides
Small bedroom (≤150 sq ft): CADR 200+ Living room (250 sq ft): CADR 350+ Open-plan (400+ sq ft): CADR 500+ Pre-filter — washable, catches hair and large dust. True HEPA H13 — non-negotiable for PM2.5. Activated carbon — for VOCs and odours. Skip ionizers — produce ozone, not helpful in tropical air. Mi Smart Air Purifier 4 (₹14,999) — best entry value. Honeywell Air Touch i9 (₹24,999) — covers larger rooms. Dyson HP09 (₹65,000) — overkill but excellent if budget allows.
