Understanding Air Quality Index
Good

Moderate
Air quality is acceptable. However, there may be a risk for some people.
Unhealthy for Sensitive Groups
Members of sensitive groups may experience health effects.
Unhealthy
Everyone may begin to experience health effects.
Very Unhealthy
Health alert: everyone may experience more serious health effects.
Hazardous
