The Air-O-Swiss AOS 7531 Demineralization Cartridge for Ultrasonic Humidifiers removes 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 AOS 7135 Digital Ultrasonic model sold by National Allergy. The Demineralization Cartridge acts invisibly and odorlessly to remove water-based minerals, while its silver-treated exterior inhibits microbial growth and odor-causing chemicals. Cartridge lasts for 2-3 months, but hard water may necessitate more frequent replacement. Package contains one (1) AOS 7531 Demineralization Cartridge.
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. Properly installed, the Air-O-Swiss AOS 7531 Demineralization Cartridge solves these problems by removing minerals from water before they are released into the air.
