classification AQI pm10 pm2.5 The health effects should be based on 24 hours average values only.
Good Air Quality 0-50 < 54 μg/m3 < 12 μg/m3 Air quality is considered satisfactory, and air pollution poses little or no risk
Moderate Air Quality 50-100 < 154 μg/m3 < 35.4 μg/m3 Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.
Unhealthy for some 100-150 < 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 Air Quality 150-200 < 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 200-300 < 424 μg/m3 < 250.4 μg/m3 Health alert: everyone may experience more serious health effects
Hazardous Air Quality > 300 > 424 μg/m3 > 250.4 μg/m3 Health warnings of emergency conditions. The entire population is more likely to be affected
