Testimonials

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.

Patty Thomas

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.

James Lucas

Now I know how well my air purifiers are working when the wild fire smoke outside is extremely hazardous, plus I'm finding out how cooking with gas, burning food, vacuuming etc. affects the indoor air. Worth every penny, peace of mind and empowering.
