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
