This has to be one of the LOUDEST air conditioning units I've ever come across. All 3 settings are noisy and difficult to ignore. If you're trying to watch tv or a movie while its on, you have to blast your tv. I'm actually a heavy sleeper and not really affected by noise when I sleep but I could NOT sleep with this AC unit on.It also takes a really long time to cool the room. I honestly gave this product a chance but the noise was unbearable and I'm returning it today. Do yourself a favor and DO NOT BUY THIS PRODUCT!
