Keep your environment hydrated with the HoMedics® TotalComfort® Plus Humidifier. This easy-to-use portable humidifier produces a micro-fine warm or cool mist that is controlled by an adjustable mist control feature. Equipped with an easy-to-remove-and-fill 1.4-gallon tank, you get up to 65 hours of runtime with an auto shut-off timer for up to 8 hours. A quiet design and on/off nightlight function allow for easy use at night. Clean Tank technology helps protect the tank from mold and mildew and a demineralization cartridge is included. As a safety measure, an automatic shut-off function is used to protect the tank when it is empty.
