Check out these air purifiers for your room and stay safe as GRAP-IV curbs return in Delhi-NCR: Picks for every budget

GRAP-IV curbs are back across Delhi-NCR this week, with stricter limits that can affect daily routines, including construction activity and commuting. If you are buying an air purifier right now, the tricky part is not the brand name. It is choosing the right capacity for your room size, how long you will run it each day, and what filter replacements will cost over a year.

In this list, we are keeping it practical with picks across budgets, plus quick checks on coverage, night noise, filter type, and what “smart” features are actually useful. We will also share simple placement and usage tips so the purifier works as intended, not just on paper.

What does GRAP IV mean for day to day life in Delhi NCR?

It usually brings tighter restrictions like curbs on construction work, stricter checks on vehicles, and steps to limit pollution sources. For residents, it often means planning commutes and keeping indoor air cleaner becomes a bigger priority.

During GRAP IV days, is it better to run the purifier 24 by 7 on auto mode, or only at peak pollution hours, and what setting works best for a typical closed room?

For GRAP IV days, treat it like this: pollution keeps leaking indoors all day, so continuous running is usually better than short bursts.

Run it continuously (day and night). Many public health guides for HEPA room cleaners recommend continuous operation, then using higher fan speeds when needed.

Use Auto mode if the sensor is reliable, but do not blindly trust it. Some sensors react more to larger particles and may not fully reflect PM2.5. If you wake up congested or the room smells smoky, bump the fan speed up for 30 to 60 minutes.

Do a “catch up” run on high for 20 to 30 minutes after any window opening, heavy cooking, dusting, or lots of door opening, then drop back to medium or sleep mode.

EPA consumer guidance also frames portable air cleaners as something you select and use in the home to reduce particle exposure, especially when outdoor air is polluted, so steady use makes sense during episodes like this.

If someone is on a tight budget during GRAP IV, what matters more for a room purifier: True HEPA, filter replacement cost, noise while sleeping, or coverage size?

If the budget is tight, prioritise in this order.

1) Correct size for your room (CADR first): If CADR is too low for the room, nothing else saves it. Use the AHAM two thirds rule as your baseline.

2) Filter availability and replacement cost: In Delhi winters, filters load up faster. A cheaper unit with hard to find filters becomes useless quickly. Plan the annual filter spend, not just the purchase price.

3) Noise at sleep settings: If it is too loud, you will switch it off at night, which defeats the purpose during GRAP IV weeks. Look for a sleep mode you can tolerate.

4) True HEPA versus “HEPA type” claims: True HEPA is a safer bet for fine particles, but do not let the label distract you from CADR and filter cost. A high CADR unit with a good particle filter and affordable replacements often beats a “HEPA” label on a weak machine.

One more budget safety filter: avoid ozone generating and some ioniser style “purifiers”. EPA warns that ozone is a lung irritant and can be produced by some electronic air cleaners and ozone generators, so it is a bad match when outdoor air is already harsh.

How do I choose the right air purifier for my room size?

• Measure your room area: Length × width in feet to get sq ft.
• Match coverage, then go one step higher: If your room is 120 to 150 sq ft, choose a purifier rated for a bigger area.
• Account for real use: Doors opening, people moving, and windows leak air, so extra capacity helps.
• Think about placement: If the purifier will sit in a corner or away from the centre, pick a higher rated model.
• Prefer faster cleaning: A higher capacity unit can run at a lower fan speed while still cleaning well, which also keeps noise down.
