A hanging radiator humidifier is a container that the user fills with water and hangs on a radiant heat source. The water is heated by the radiator, and it evaporates into the air of the room, increasing the humidity level.
Hanging radiator humidifiers are made from ceramic, metal, or plastic, and are more commonly available in the United Kingdom, but online shoppers have a limited selection available to them in the United States as of 2014. This product helps to humidify the air in the home created by dry, cold air and indoor heat. Using a humidifier near the home's heat source keeps skin moist, and it reduces static electricity in the home.
