Air quality in Bareilly
How bad is the air in Bareilly?
Bareilly’s 2025 average of AQI 76 is Satisfactory on the CPCB scale, and the median day was 76. 54 days crossed 100 (Moderate or worse) and 1 crossed 200 (Poor or worse).
The peak was AQI 225 on 21 November 2025. Coarse dust (PM10) set the index on 67% of days.
When Bareilly’s air is worst
December is the worst month at a mean of AQI 103; February the cleanest at ~49. 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 December covers the rest of the year with headroom, and windows can be opened in February.
Pollution in Bareilly: what drives it
Across Uttar Pradesh, the usual drivers of poor air are vehicle exhaust, construction and road dust, biomass and stubble burning in the post-monsoon months and winter temperature inversion that traps pollution. CPCB bulletins name coarse dust (PM10) as the prominent pollutant on 67% of 2025's days.

Do you need an air purifier in Bareilly?
Verdict
Not essential — Bareilly's outdoor air stayed Satisfactory most of the year.
Only 54 of 350 bulletin days went above Satisfactory. Indoor sources (cooking, incense, dust, a busy road outside) can still justify a purifier for a nursery or an allergy household, and sizing still matters — see the calculator.
What actually works
- Size by volume, not the box. Coverage claims assume ~2 air changes an hour; a December 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.
