Air Quality Index Levels of Health Concern Numerical
Value
Meaning
Good
0 to 5
Air quality is considered satisfactory, and air pollution poses little or no risk.
Moderate
51 to 100
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 Sensitive Groups
101 to 150
Members of sensitive groups may experience health effects. The general public is not likely to be affected.
Unhealthy
151 to 200
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Very Unhealthy
201 to 300
Health alert: everyone may experience more serious health effects.

Health warnings of emergency conditions. The entire population is more likely to be affected.
Action day
Action days are usually called when the AQI gets into the unhealthy ranges. Different air pollution control agencies call them at different levels. In some places, action days are called when the AQI is forecast to be Unhealthy for Sensitive Groups, or Code Orange. In this case, the groups that are sensitive to the pollutant should reduce exposure by reducing prolonged or heavy exertion outdoors. For ozone this includes: children and adults who are active outdoors, and people with lung disease, such as asthma. For particle pollution this includes: people with heart or lung disease, older adults and children. Occasionally, an action day is declared when the AQI is Moderate, or Code Yellow, if the levels are expected to approach Code Orange levels.
