Air quality in Kolhapur
How bad is the air in Kolhapur?
Kolhapur’s 2025 average of AQI 71 is Satisfactory on the CPCB scale, and the median day was 60. 71 days crossed 100 (Moderate or worse) and 3 crossed 200 (Poor or worse).
The peak was AQI 250 on 11 December 2025. Coarse dust (PM10) set the index on 80% of days.
When Kolhapur’s air is worst
December is the worst month at a mean of AQI 133; August the cleanest at ~31. 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 August.

Do you need an air purifier in Kolhapur?
Verdict
Not essential — Kolhapur's outdoor air stayed Satisfactory most of the year.
Only 71 of 352 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.
