High-Quality Raw Materials: The enhanced desalination box can improve the internal environment of the humidifier tank while removing odors from the water, providing a clean and comfortable environment and your family. This is because it is rich in activated carbon and cationic resin, through ion exchange technology, blocks magnesium and calcium to form hard water and removes odor. EASY INSTALLATION: Simply place 1 Ultrasonic Desalination Filter in your humidifier tank and start enjoying a clean, pure mist. Replace filter elements every 30 to 40 fills, depending on water hardness. SUPERIOR PERFORMANCE: Our ultrasonic humidifier demineralization filter does an excellent job of reducing white powder buildup caused by minerals in hard water. It effectively purifies water and prevents odor emissions by absorbing calcium, and magnesium ions contained in hard water. Plus, the desalination helps keep your humidifier at operating condition and capacity for a healthier breathing environment Reduces White Dust: Ultrasonic filters help prevent the buildup of white dust caused by minerals and chemicals in hard water, which may contain calcium, , or magnesium. These desalination filters help extend the life of your humidifier motor and tank by purifying the water inside and keeping it clean. Extend the life of your humidifier: the humidifier desalination filter works just like the filter.
