SLCgreen is helping the Utah Division of Air Quality to remind residents to download the app, UtahAir. The updated app will now send action alerts and three-day forecasts based on current conditions to help people plan the best times to exercise outdoors or drive. The app, for both Android and iOS users, can be downloaded at air.utah.gov.

Pollution is a complex airborne mixture of solid particles and liquid droplets called particulate matter. The particulate matter is classified as fine particles, PM2.5, or coarse particles, PM10. These tiny particles can obscure our view of the mountains and buildings on bad days.
PM2.5 particles are so small and light, they stay in the air longer than larger heavier particles. This increases the chances of humans and animals inhaling them into their bodies. Particles that are smaller than PM2.5 are thirty times smaller than a human hair and are able to bypass the filtering system in our nose and throat into the lungs. Read more
