Guardian Technologies PureGuardian 1.5 Gal. Cool and Warm Mist Ultrasonic Tabletop Humidifier

Unlike other humidifiers that grow slimy mold and mildew, the PureGuardian100-Hour Ultrasonic Humidifier uses silver clean technology to fight the growth of mold and mildew on the surface of the water tank. It is ultra-quiet when it runs making it ideal to have on while you sleep. The humidifier is equipped with the option for both warm or cool mist and a low water indicator light lets you know when it is time to refill the water tank. It features a soft glow night light that turns on and off.
