I bought this purifier about two weeks ago and I can tell the difference. I really think the air I breathe is cleaner and helps me because my lungs are not as good as a average man. I studied and reviewed many reviews. I feel I made the right choice. It's a quality well built unit. FINLEY H.
I received excellent help from Otto P in diagnosing a problem with the particle detection. With his help I was able to resovle the problem in 5 minutes. Great work OTTO
It was critically important for me to get this filter. I have COPD and the smoke from the wildfires in Canada and the west coast of the US still affects me inside my home due to air infiltration. This air purifier is a life saver for me!
