PurpleAir: Real-time air quality monitoring everyone can use.
We make sensors that a community of citizen scientists use to collect hyper-local, real-time air quality data and share it on a map that is accessible to everyone.
Sensors that are sensitive to particulate matter. And your budget.
Our industry leading sensors are priced at a fraction of what you’d pay for a commercial sensor, are easy to install and connect seamlessly to your WIFI network.
The PurpleAir PA-II sensor is very reliable. Three years ago we deployed 25 sensors throughout our region and they are all still running strong with high confidence.

I ordered a sensor last year to get accurate air quality readings in my neighborhood. The sensor works GREAT, customer service is GREAT, and I have no complaints. Highly recommend this product and company.
