A cleaner way to humidify. From HoMedics, this set of four demineralization cartridges helps prevent calcium and lime buildup in your ultrasonic humidifier. It also reduces mineral buildup and "white dust" caused by hard water. To use, simply drop a cartridge into your ultrasonic humidifier's tank when filling. Replace the cartridge every 30 to 40 fillings, depending on your water's hardness. From HoMedics.
