Welcome to the Tanana Valley Clinic Air Quality information page. Here at the Allergy and Asthma Department, we track air quality with the assistance of air pollution detecting devices called "Purple Air". The name references the purple zone of the air quality index chart, where “everyone may experience more serious health effects”. The below chart reflects air quality data collected by sensors located on the roof of Tanana Valley Clinic.

We employ these devices at the clinic, but many other individuals in our area, and all over the globe, have them up and running. Pollution levels can be followed online, in real time.
