Community air monitoring projects that use air sensor technology to monitor air quality in EPA’s Region 10 are providing the public with more information on the quality of the air they breathe.

EPA’s Region 10 serves Alaska, Idaho, Oregon, Washington, and 271 tribal nations.

EPA is providing low-cost sensors capable of providing environmental awareness information associated with fine particulate matter (PM2.5), environmental conditions, and location (GPS) measurements to develop an enhanced understanding of PM2.5 air quality variability in or near school locations.
