The device works very well and keeps our bedroom (bathroom in the same room) pleasant "dry" noise is hardly noticeable with the door closed in other rooms. Sleeping or watching TV in the same room while the unit is running are impossible for it makes the dehumidifier too much wind and noise. But if it run during the day can be just fine. Within 3 days of the day is then packed to the rafters. A dehumidifier on salt cartridge base would be much too expensive for us.
