    Boneco/Air-O-Swiss 7531 Demineralization Cartridge

    This demineralization cartridge is a standard component in any ultraonsic BONECO/AIR-O-SWISS humidifier. It sits in the water tank and traps the minerals found in hard water. Using and regularly replacing the demineralization cartridge in your humidifier can prevent white mineral dust from being released into the air, and it keeps the tank free of scale. Refill with replacement granules or replace the entire cartridge every two to three months. Replacement granules also are available. Part/Model No. 7531

    Product Questions

    What is the demineralization cartridge made of? I'm interested in the ingredients inside the cartridge that keeps mineralization from occurring.
