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 sensor.
OUR GUARANTEE
We've got you covered. Our one-year limited warranty ensures that if your device has any manufacturing defects, we’ll troubleshoot, repair, or replace it free of charge. If you're not happy, you can return it within 30 days of purchase for a full refund, no questions asked.
SUPPORTING LOCALS
Did you know that we design and assemble our products in Salt Lake City, Utah? By sourcing as many components as possible from local suppliers, we proudly support our community while ensuring the highest quality and attention to detail in every sensor we produce.
Access The World's Largest Air Quality Dataset
The PurpleAir API is a web service that allows you to obtain air quality data reported by PurpleAir sensors. This extensive dataset goes back to early 2016 and can be integrated into your applications to develop innovative solutions for monitoring and analyzing air quality trends.
