Air Quality Washington

Real-time air quality monitoring app for Washington

Washington State Department of Ecology’s Air Quality Program maintains an air monitoring network to accurately measure air pollution and meteorology conditions around the state in partnership with EPA, Tribes, and local clean air agencies.
We use this smart phone app to inform the public about current air quality conditions and provide guidance that people can use to protect their health when air quality is not good.
Most recently collected data have yet to be thoroughly reviewed for validity and should be considered preliminary.
