FEATURED RESOURCE
The US EPA's Fire and Smoke Map is a great resource to see additional information about wildfire smoke. It combines government sensors and PurpleAir as well as locations of wildfires in one view.
WHO WE ARE
PurpleAir makes sensors that empower communities who collect hyper-local, real-time, air quality data and share it with the public. Our industry-leading sensors measure particle pollution (PM2.5) and are priced at a fraction of what you pay for a commercial air quality monitor.
