Classification AQI pm10 pm2.5 The health effects should be based only on 24-hour average values
Good 1-50 < 54 μg/m3 < 12 μg/m3 Air quality is considered satisfactory, and air pollution poses little or no risk

Moderate 51-100 < 154 μg/m3 < 35.4 μg/m3 Air quality is acceptable; however, for some pollutants there may be moderate concern for a very small number of people who are unusually sensitive to air pollution
Unhealthy for some 101-150 < 254 μg/m3 < 55.4 μg/m3 Members of sensitive groups may experience health effects, the general public
is not likely to be affected
Unhealthy 151-200 < 354 μg/m3 < 150.4 μg/m3 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects
Very Unhealthy 201-300 < 424 μg/m3 < 250.4 μg/m3 Health alert: everyone may experience more serious health effects

Hazardous ≥ 301 > 424 μg/m3 > 250.4 μg/m3 Health warnings of emergency conditions, the entire population
is more likely to be affected
