The purpose of the AQI is to help you understand what local air quality means to your health.
To make it easier to understand, the AQI is divided into six categories:
|Air Quality Index
|Levels of Health Concern||Colors|
|When the AQI is in this range:||..air quality conditions are:||...as symbolized by this color:|
|101-150||Unhealthy for Sensitive Groups||Orange|
|151 to 200||Unhealthy||Red|
|201 to 300||Very Unhealthy||Purple|
|301 to 500||Hazardous||Maroon|
EPA has assigned a specific color to each AQI category to make it easier for people to understand quickly whether air pollution is reaching unhealthy levels in their communities.
For example, the color orange means that conditions are "unhealthy for sensitive groups," while red means that conditions may be "unhealthy for everyone," and so on.
|Air Quality Index Levels of Health Concern|| Numerical
|Good||0 to 50||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 warnings of emergency conditions. The entire population is more likely to be affected.|
|Hazardous||301 to 500||Health alert: everyone may experience more serious health effects|
