When Meerut’s air is worst
November is the worst month at a mean of AQI 311; July the cleanest at ~60. That is the post-monsoon pattern: cooler nights lower the mixing height, winds drop, and whatever the city emits stays over it.
Plan around the profile, not the average: a purifier sized for November covers the rest of the year with headroom, and windows can be opened in July.

Do you need an air purifier in Meerut?
Verdict
Yes — Meerut needs one for a good part of the year.
With 88 days at Poor or worse and an annual average of 148, a bedroom-sized HEPA purifier run at 5 air changes an hour is the difference between sleeping in "Poor" air and "Satisfactory" air. Size it from room volume, not the coverage figure on the box.
What actually works
- Size by volume, not the box. Coverage claims assume ~2 air changes an hour; a November night wants 5.
- Bedroom first. Eight closed-door hours a night is where a purifier makes its measurable difference.
- Watch the live number. On Good and Satisfactory days, ventilate; on Poor days, close up and run the unit at the speed that delivers its CADR.
