Duracraft DH901 is a humidifier that produces warm moisture. It is equipped with the Mist Breaker™ Safety System, which automatically shuts the humidifier off if it is accidentally tipped over, runs out of water, or the tank is removed. The humidifier has a variable moisture output control, so you can adjust the amount of moisture it produces to suit your needs. It also has a built-in medicine cup, so you can add medication to the vapor to help relieve cold and flu symptoms. The humidifier is easy to clean, with a Rinse-to-Clean® base that makes it easy to remove scale buildup.
