I don't think this is noisy at all. You do hear the fan but your supposed to use this in a small room/area or a bathroom. With that being said, you keep the door closed or almost all the way closed to the unit can filter the air. It works well in my opinion....my wife agrees. We use it in the guest bathroom. Whenever we have guests over we just leave it on. It's not the prettiest thing to have in the bathroom depending on where your outlet is but it's also not that bad. Guests always ask about it.
