classification AQI pm10 pm2.5 The health effects should be based on 24 hours average values only.
Good Air Quality 0-1 < 20 μg/m3 < 10 μg/m3 Air quality is considered satisfactory, and air pollution poses little or no risk
FairAQ 1-2 < 40 μg/m3 < 20 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.
Moderate Air Quality 2-3 < 50 μg/m3 < 25 μg/m3 Members of sensitive groups may experience health effects. The general public is not likely to be affected.
PoorAQ 3-4 < 100 μg/m3 < 50 μg/m3 Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
VeryPoorAQ 4-5 < 150 μg/m3 < 75 μg/m3 Health warnings of emergency conditions. The entire population is more likely to be affected
ExtremelyPoorAQ > 5 > 150 μg/m3 > 75 μg/m3 Health alert: everyone may experience more serious health effects
