It's works! But does have a noticeable hum to it
I bought this shortly after getting a dog to make sure my condo would still smell nice and it really works! My place smells fresher than ever. Other reviewers mentioned the hum but wow, it's pretty loud! If the TV is off even my guests notice it. I love having it in my living room and would've bought another for the bedroom but I won't because the noise would bother me while I'm trying to sleep.
