Vornado® Demineralization Cartridge
Ordinary tap water can be full of hard minerals such as lime and calcium. When this water is vaporized a white dust can form, a kind of residue that can build up inside your living space. This Mineral Cartridge is specifically designed for use with your Vornado Ultrasonic Humidifier and will reduce this buildup from occurring. It absorbs hard water minerals and reduces scale build-up inside the humidifier. Model # MD1-0018.
