The Intelligent Water Filter Coffee is 98% water. So water of the highest quality is essential to creating the best possible coffee experience. The CLARIS Pro Smart from JURA revolutionizes water filtration. For the first time, thanks to modern RFID (Radio-frequency Identification) technology, a coffee machine can continually communicate with the filter. It recognizes whether a filter has been inserted and automatically activates the appropriate mode. It continually collects information about filter use and alerts the user when the filter capacity has been exhausted. This not only makes changing the filter easier than ever before but also allows the CLARIS Pro Smart to achieve optimum effectiveness.
