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.

Brilliant company, responsive to customers' needs. The sensors are an excellent product and are gaining many fans in New Zealand.
What would you do if you thought your air quality might be poor? This group of students in Milton, Ontario, decided to take matters into their own hands. They deployed PurpleAir sensors in the North and South of Milton and collected data over a period of approximately one month.
