So far so good. We have had it about a week. It’s quiet and putting it on auto it does work on it’s own. The house smells nicer and air smells cleaner. We do not regret getting it. It’s bigger than what we thought but it’s nice looking so it fits in the living room. I would recommend it. My sister recommended it to us, and we are satisfied with it’s performance and effectiveness. Shipping did not take long either.
