The AQI is the highest of these sub-indices, on the CPCB National AQI (India) scale. Both standards are defined over 8- and 24-hour averages; readings here are instantaneous, so treat short spikes with care.
What you should do

What is a safe AQI level in India?
On India's CPCB National Air Quality Index, an AQI of 0–50 is Good and 51–100 is Satisfactory — both are safe for outdoor activity for everyone. From 101–200 (Moderate), people with asthma or heart and lung conditions should limit prolonged exertion. 201–300 (Poor) causes breathing discomfort on extended exposure, 301–400 (Very Poor) affects most people, and 401–500 (Severe) is hazardous to everyone. India's CPCB scale is stricter in its lower bands than the US EPA scale, so the same air can read as a different category depending on which standard you use.
| AQI (CPCB) | Category | Who is affected |
|---|---|---|
| 0–50 | Good | No one — safe for everyone, including sensitive groups |
| 51–100 | Satisfactory | Minor breathing discomfort for the unusually sensitive |
| 101–200 | Moderate | People with asthma, and heart or lung conditions |
| 201–300 | Poor | Most people on prolonged exposure; discomfort is common |
| 301–400 | Very Poor | Respiratory illness on prolonged exposure for everyone |
| 401–500 | Severe | Everyone; serious effects on those with existing conditions |
How we calculate AQI
Each of the six pollutants — PM2.5, PM10, ozone, NO₂, SO₂ and CO — is converted to a 0–500 sub-index through the standard's piecewise-linear breakpoint table, and the AQI is the highest of them. The pollutant that produced it is the dominant one, which is what a PM2.5-only number can never tell you. One limitation worth stating plainly: both CPCB and US EPA define their breakpoints over 8- and 24-hour rolling averages, while our source (OpenWeatherMap) reports instantaneous concentrations. What we publish is therefore the AQI if the current concentration held for the full averaging window — which overstates short spikes and understates a day that is only just clearing.
