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 build-up. Completely odorless, this filter scrubs your water clean, extending the life of your humidifier. Receive free shipping on future mineral cartridge orders when you setup a product subscription.
