Humidifier is used in winter to prevent dryness in your room. There are three types of humidifier, Vaporizer (steam humidifier, warm mist humidifier), Impeller humidifier (cool mist humidifier), and Ultrasonic humidifier (a metal diaphragm vibrating at an ultrasonic frequency creates water droplets that silently exit the humidifier in the form of a cool fog). If you are looking for the third type of humidifier, there is one from Brookstone called Broksonic Ultrasonic Humidifier and Disffuser.
