This machine worked fine...until it didn't. It quit a couple of times, but honestly, maybe the kids had it on the timer. Not sure.Then it started to make a noise, much more than it was supposed to. Off and on. We decided to return it for a more costly model. It DID clean the air very well, according to our air quality reader, so there's that if you don't have to sleep in the same room with it.
