Pure Guardian Digital 144-Hour Ultrasonic Humidifier

The Pure Guardian 144-hour ultrasonic digital humidifier uses silver clean technology to prevent the growth of mold and bacteria in the water tank. The ultrasonic humidifier has over a 2.4 gallon tank capacity with a low water indicator light that turns on when it is time to refill the tank. The humidifier is ultrasonic so it's virtually silent when it runs, making it ideal to have on while you sleep. There are no added costs with the unit since there are no evaporating pads, filters or wicks to clean or replace. The high output nozzle broadens mist in two directions throughout the room and the soft blue night light is controlled with an on/off switch. Model # H-4600.
