Air Quality Index

The purpose of the Air Quality Index (AQI) is to help you understand what local air quality means to your health. The higher the AQI value, the greater the level of air pollution, which means the greater the health concerns. It’s an easy way to determine if you can enjoy the outdoors as usual or if you should consider planning an indoor activity to reduce exposure to polluted air.
