Do you need an air purifier in Surat?
Verdict
Not essential — Surat's outdoor air stayed Satisfactory most of the year.
Only 62 of 290 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 July 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.
