Air Purifier Buying Guide — Do You Really Need One?

Every winter, AQI numbers across North India make the case themselves. Here's when an air purifier genuinely helps — and how to choose one that does.

Who benefits most

Homes with kids, elderly family members, asthma or allergies see the clearest gains, especially through the October–January smog months. Bedrooms are the highest-value room to purify — you spend 8 hours a night there.

The two specs that matter

• True HEPA filter — captures the fine PM2.5 particles that cause the harm. Non-negotiable.
• CADR matched to room size — the clean-air delivery rate must suit your room's square footage; an undersized purifier cleans nothing meaningfully.

Also check

• Filter replacement cost — filters need changing every 6–12 months in North India winters; budget for it.
• Noise on sleep mode — you'll run it all night in the bedroom.
• Activated carbon layer — handles odours and gases alongside particles.
