Air Quality Index (AQI)

The Air Quality Index (AQI) is a color-coded tool for reporting air quality. It provides simple information on local air quality, the health concerns for different levels of air pollution, and how you can protect your health when pollutants reach unhealthy levels. Measured concentrations of air pollutants are converted to the AQI scale of 0 to 500.

In some areas of Washington, air quality is reported using a similar tool as the AQI, but with different thresholds. It's called the Washington Air Quality Advisory or WAQA, and it was developed by Ecology. Learn more about WAQA here. 

Spokane Clean Air reports two AQIs: The Current AQI (reflects near real-time conditions) and the Official or Daily AQI.
