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.
CO or Carbon Monoxide is a colorless and oderless gas. If inhaled constantly or the concentrations are too high, it can affect our health severely. Vehicles and other machinery that burns fossil fuels represent the most significant sources of CO.
Particle pollution is one of the most common pollutants, and often it is not clear what we can or should do in each air quality index level. There are six levels, from good to hazardous.
Last week was the International Hand Launch Glider Festival, the largest gathering of radio-control discus launch gliders in North America. No, PurpleAir hasn't pivoted into making RC toys, but it holds a special place in our hearts. This hobby provided me (Adrian Dybwad) with the building blocks for creating the first air quality sensors that have grown into the PurpleAir we all know and love today.
