How to Choose for Delhi NCR

Prioritise true HEPA filtration and a CADR suited to your room. In severe pollution, a purifier that is too small will struggle, so err on the larger side.

Look at the sensor and auto mode. A PM2.5 sensor helps the purifier adjust speed as air quality changes, saving noise and energy on cleaner days.

Plan for filters and electricity. Filters need replacement, and running a purifier for many hours a day adds to the bill.

Common Mistakes to Avoid

Leaving doors and windows open. Keep the room closed while the purifier runs.

Ignoring the second room. One purifier covers one room. Use one in the bedroom first.

Skipping maintenance. Clean pre-filters and replace filters on schedule.

Quick FAQ

Can a purifier fix Delhi's air? It cleans indoor air in a closed room, but it does not change outdoor pollution.

How long should I run it? Many users run it for most of the day during severe pollution.

Do I need a mask indoors? A purifier reduces particles in a closed room, but follow medical advice for health concerns.

Placement and Running Costs

Start with the bedroom, since it is where most people spend the longest continuous time. Keep windows and doors closed, and place the purifier a little away from walls so it can draw air in. If you have a second unit, use it in the room where you spend the day.

Budget for filters and electricity. In heavily polluted areas filters can clog faster, so replacement may be needed sooner than the stated interval. Check the filter price and availability before you buy, and use the auto mode to save noise and power on cleaner days.

Real-World Scenarios

A bedroom with children. Choose a quiet model with a night mode and a reliable auto function, and keep windows closed.

A work-from-home room. Look for a unit with low noise at the middle speeds, since you will run it during working hours.

A ground-floor flat near traffic. Expect faster filter loading and check that pre-filters can be washed.

A home with asthma or allergies. Prioritise true HEPA and a sensor-driven auto mode, and consider a second unit for the main living area.

What to Check on the Listing

Confirm the CADR, room area rating, filter type and replacement cost. Check noise levels and whether an air quality display is included.

Recommendation

For bedrooms, the Philips AC2887 or Coway Airmega 150 is a solid choice. For larger rooms, look at Xiaomi 4 Pro or Blueair. Dyson is a premium option for those who want extra features.
