DR. INFRARED HEATER Elite Series DR-998W can help you prevent cold, dry winter air, and save money on your heating bills. DR. INFRARED HEATER Elite Series DR-998W is the world’s first infrared space heater that combines ultrasonic mist vapor with oscillation to increase the heat transfer rate, producing a superior level of therapeutic comfort you'll want to experience for yourself. The DR. INFRARED HEATER DR-998W actually takes the place of three different appliances. It works as a humidifier, infrared heater, and oscillation fan. The built-in silent ultrasonic humidifier adds much needed moisture to dry winter air, and the oscillation function evenly distributes warm, moist air throughout your entire room fast.
