Simply drop one of these demineralization cartridges into your ultrasonic humidifier tank to prevent calcium and lime build-up caused by hard water. These cartridges work with Sharper Image humidifier models EVHD10, EVHD15 and EVHD20. Replace the cartridge every 30 or 40 fillings, depending on your water hardness. Includes 4 cartridges.
