Problem
The general public lacks access to affordable and easily deployable tools for hyperlocal air quality monitoring. Existing commercial-grade sensors are often too expensive for widespread community use, hindering efforts to understand and address localized pollution variations.
Solution
PurpleAir manufactures and distributes low-cost, laser-based air quality sensors that enable community scientists and individuals to monitor particulate matter (PM2.5) in real-time. These sensors connect to WiFi networks and transmit data to a public map, creating a dense, crowdsourced network of air quality information. The data is also accessible through a developer API, allowing integration into various applications and research projects. PurpleAir's sensors empower communities to understand air pollution patterns, make informed decisions, and advocate for cleaner air.
Target Audience
The primary audience includes community scientists, individuals concerned about air quality, schools, researchers, and organizations seeking hyperlocal air quality data.
