India has 9 of the world’s 10 most polluted cities. Delhi’s AQI regularly crosses 400 in winter; Mumbai, Kolkata, and Lucknow aren’t far behind. Even in relatively cleaner cities like Pune and Hyderabad, indoor air can be 2–5x more polluted than outdoor air due to cooking fumes, dust, and poor ventilation. An air purifier with a HEPA filter removes 99.97% of particles including PM2.5, dust, pollen, pet dander, and smoke — and under ₹5,000, there are genuinely effective options. Here’s our guide for 2026.
What to Look for in an Air Purifier for Indian Homes
Key specifications that matter for Indian conditions:
- CADR (Clean Air Delivery Rate): Measured in m³/hour — higher is better. For a 150 sqft bedroom, you need at least 150 m³/hr CADR.
- True HEPA filter: Must say “True HEPA” — removes 99.97% of particles ≥0.3 microns including PM2.5. “HEPA-type” filters are inferior.
- Activated carbon layer: Removes cooking odours, VOCs, and gaseous pollutants — important for Indian kitchens
- Room coverage area: Always buy for 1.5x your actual room size to account for Indian pollution levels
- Filter replacement cost: Check before buying — some purifiers have expensive filters (₹2,000–₹4,000 every 6 months)
