If you have hard water, there is nothing more annoying than breathing in white mineral dust from your humidifier and later trying to remove the hard scale buildup that accumulates inside the humidifier. The Air-O-Swiss 7531 Demineralization Cartridge solves these problems by removing minerals from water before they are released into the air.
Use of the Demineralization Cartridge also prevents lime scale and other buildup from forming on the interior of any Air-O-Swiss Ultrasonic Humidifier, including the Air-O-Swiss 7135 Ultrasonic Digital Humidifier
sold by Allergy Control Products. The Demineralization Cartridge acts invisibly and odorlessly to remove water-based minerals, while its silver-treated exterior inhibits microbial growth.
