What’s new

Version 1.2 · Updated August 29, 2021

With this release, you can toggle between the default EPA air quality readings and the raw PurpleAir air quality numbers that you see on the PurpleAir web site. While the EPA numbers more accurately represent US EPA air quality, so many users have asked me about the discrepancy, I wanted to provide access to both in the app. Please keep the feedback coming!
