Best suited for rooms up to 1400 square feet in size, the humidifier's heater is crafted in stainless steel for quick heat production and trouble-free cleaning. The compact humidifier outputs 4 gallons of warm steam for each full tank of water. This humidifier offers users a timer function for running the unit for preset periods, ranging from an hour to the maximum 18-hour setting. Digital controls and the easy-to-read LCD screen enable users to alter or monitor current preference settings. A medicine cup allows users to run the humidifier as a vaporizer for stuffed noses, sore throats and other respiratory illnesses. An automatic shutdown feature reduces safety hazards. Humidifier water should be changed frequently and the tank washed well each week to prevent bacteria, mold, and other impurities from developing, though the heating process should kill many of these unhealthy particles. As with any electrical home device, read all manufacturer guidelines and instructions prior to use. This humidifier measures 15.55 by 14.57 by 10.24 inches and weighs 6 pounds upon shipping. --Jessica Reuling
