What do these numbers mean?
The Air Quality Index (AQI) is a single 0โ500 score used by India's Central Pollution Control Board (CPCB) to describe how polluted the air is right now, combining PM2.5, PM10, NOโ, SOโ, CO and Oโ into one number. India's official bands run 0โ50 Good, 51โ100 Satisfactory, 101โ200 Moderate, 201โ300 Poor, 301โ400 Very Poor, and 400+ Severe. Anything above 200 is generally considered unsafe for prolonged outdoor activity, especially for children, older adults, and anyone with respiratory or heart conditions.
