PurpleAir makes sensors that empower communities who collect hyper-local, real-time, air quality data and share it with the public.
Our Sensors
Tested By
U.S. EPA Fire and Smoke Map
This map relies on data provided from a number of sources, including AirNow, the Western Regional Climate Center, AirSis, and PurpleAir for monitoring and sensor data, and the NOAA Hazard Mapping System and National Interagency Fire Center for fire and smoke plume information.
AIR QUALITY IN SCHOOLS
Ford Dream Builders installed PurpleAir sensors in Bakersfield, CA schools, providing students with air quality data. This empowers classrooms to learn about air pollution and make healthier choices.
WHO WE ARE
Made with care in the USA, our industry-leading sensors measure particulate pollution (PM2.5), temperature, humidity and pressure. They are priced at a fraction of what you pay for a commercial grade air quality monitor without sacrificing quality and data accuracy.
Access The World's Largest Air Quality Dataset
The PurpleAir API provides access to air quality data from PurpleAir sensors, with records dating back to 2016. It enables integration into applications for monitoring and analyzing air quality trends.
