About Our Air

Thanks to decades of hard work and technological advances, air quality in the Spokane region is good on most days. However, there are days when air pollution is in the upper-moderate to unhealthful ranges. These are typically cold, calm winter days when wood smoke becomes concentrated. Local air quality can also be impacted by natural events such as wildfires and dust storms.  

Air Pollutants of Concern - In the Spokane region there are two pollutants of primary concern, fine particles and ground-level ozone. While industry contributes to about 20% of our air pollution, most of it comes from individual actions related to how we travel and heat our homes.

Air Quality Monitoring - Agency staff operate a network of 10 air quality monitoring stations located throughout Spokane County. Information collected is used to provide daily air quality forcasts, to notify the community when air quality is approaching unhealthful levels, and to identify potential pollution problems and solutions.

Seasonal Air Quality Issues - Air quality in the Spokane region tends to decline during the winter heating season and during the hot, summer months. Learn more about our seasonal challenges and what you can do to reduce air pollution. 

Air Quality Publications - A variety of fact sheets and brochures are available on numerous air quality topics, including wood heating, outdoor burning, and asbestos.

Air Quality Reports and Maps- monthly air quality reports for the last five years, emissions inventories, special monitoring project reports, and CO and PM10 maintenance area maps.
