Great air filter
We have been using your filters for several years and are very happy with the results. With the wildfires and other pollution everywhere, it is very important to have clean air wherever you are most of the time.

Very effective
We live in Arizona where particulate matter in the air is quite high. The Blueair filter does an excellent job of keeping the air in pout apartment clean.
