This ceramic humidifier is designed to revitalise stale dry air and replace lost moisture. Simply hang over radiators, fill with water and the heat from the radiator evaporates the water helping you to replenish moisture in an over the dry room. This system helps protect furniture and helps create healthy ambient air conditions. This simple humidifier also allows you to fragrance your space by adding aromatic oils to the water stored within it, which will evaporate as part of the process and fragrance the room or area.
