The CLARIS Pro Blue filter contains a special formula developed for commercial automatic machines with a one-touch cappuccino function. It stabilizes calcium carbonate to prevent limescale buildup in your Jura machine's fluid system, even during frequent steam preparations. The filter also reduces harmful substances in water while retaining beneficial minerals for flavor enhancement. It works effectively with any mains water, hard or soft, to generate optimal quality water. Using the CLARIS Pro Blue correctly eliminates the need for descaling, reducing maintenance costs and ensuring efficient machine operation. This prevents calcium carbonate buildup in the inner workings, reducing the risk of failure for heating elements, pumps, and pipework, thus preserving your machine's lifespan. The CLARIS Pro Blue is designed for commercial Jura machines with a blue filter holder in the water tank, including the IMPRESSA XJ series and GIGA X machines.
