What's a PurpleAir Map?
The PurpleAir Map is the United States Environmental Protection Agency (EPA) Air Quality Index (AQI) scale for PM2.5. The AQI allows comparison for different pollutants with an easy-to-visualize color scheme. The scale goes from good, green air to more hazardous, maroon air. The graphs give further information on different counts, relative weights and sizes of particles in the air. Every icon on the PurpleAir map represents a public PurpleAir sensor, and the color indicates the real time PM2.5 reading on the US EPA Air Quality Index scale.
