Pure GuardianPureGuardian H7550 Ultrasonic Warm and Cool Mist Digital Humidifier

The 90 hour Ultrasonic Warm and Cool Mist Humidifier guards against problems caused by dry air in the home. It features an easy to fill large 1.32 gallon tank, ideal for use in medium sized rooms. Unlike other humidifiers that grow slimy mold on the water tank surface, Silver Clean™ Protection is embedded in the tank to fight the growth of mold and mildew on the surface of the water tank. Thanks to ultrasonic technology, it disperses a fine warm or cool mist into the air, which can be extended using the wands. It is ultra quiet making it ideal to have on while you sleep. Smart mist sensor monitors the level of humidity in the room and adjusts to your selected level. The humidifier is equipped with an easy to use digital display, a night light, timer and 3 speed mist control. A low water indicator light lets you know when it s time to refill the water tank. PureGuardian® humidifiers create a better home environment for those suffering from colds, allergies and dry skin. Note: Run time is based off of running the unit on low setting and cool mist, also depends on atmospheric conditions.
