Effectively relieve dry nose, throat lips and itchy skin with the virtually silent Dual Mist Humidifier with ION exchange filter. Will help you breathe easier and sleep more comfortably. This ultrasonic humidifier disperses warm or cool mist. A split nozzle for bi-directional mist for wider coverage. Sleek design with easy to use control knobs. Large, transparent blue water tank with easy-carrying handle. ION exchange filter demineralizes and treats water to remove scale-forming calcium and magnesium from hard water. This prolongs the life of the ultrasonic generator and prevents white dust particles to deposit into the air.
The easiest way to check if the warm mist function is working or not: after the unit runs for 10 mins, turn the power off, lift the water tank and feel the water in the reservoir. The water temperature should be around 100-110 when the ambient temperature is 65 degrees. It varies depending on ambient room temperature. The fan inside the humidifier makes a humming noise when it's functioning.
