My son is allergic to dust mites, the room must have a specific humidity level, the humidifier and the surface of the room is perfect, it holds a reasonable level of water, we can adjust the intensity for the sending the air, it stops automatically once the tank is empty, silent and hygrometer which is accompanied with a more is to monitor room temperature or humidity. The weak point as stated in other reviews and I confirm totally! the length of the outlet is very short! extension required! otherwise good product! I recommend.
