Vornado MD1-0018 Replacement Ultrasonic Mineral Cartridge, 1, Black

Ordinary tap water is full of lime, calcium and a host of other minerals. When this water is vaporized, "white dust" can form - a kind of residue buildup that can develop on your walls, floors and furniture. The Vornado Mineral Cartridge is specifically designed for use in your Vornado Ultrasonic Humidifier to help filter out the minerals that cause this dust to form. The cartridge contains a specially designed blend of water softening minerals, reducing lime and calcium buildup. Completely odorless, this filter scrubs your water clean, extending the life of your humidifier. This Mineral Cartridge, part number MD1-0018, works with models UH100, Ultra1, Ultra2 and Ultra3.
