The powerful ion exchanger in the Cartridge removes calcification in the water to prevent white dust often created by ultrasonic systems. It lasts up to three months, depending on the water's hardness. Suitable for most ultrasonic humidifiers with a standard tank cover.
The Ionic Silver Cube's patented Swiss Technology keeps water clean in humidifiers. Releasing silver ions into the water, it inhibits bacterial growth for more hygienic humidification. Should be replaced once a year.
