So far so good. It's very quiet. Does a fairly descent job with removing cooking odors (bought the upgraded filter for that), the smells or lack thereof is noticeable. As for air purification, it's on automatic and it does go green, but no real qualitative feel as to whether it's helping with air quality or not... I have the sense that it is, but will need more time to know for sure. Just having the sense that the air is cleaner makes one mind more at ease and thus one's body more at rest.
