Not all coffee filters are created equal. The Jura 72629 Smart Filter Cartridge (Grey) revolutionizes water filtration for the best tasting coffee. Its intelligent water system (I.W.S.) removes chlorine, lead, aluminum, and copper, while an organic additive eliminates almost all calcium carbonate to prevent scale build up. Thanks to modern RFID (Radio-frequency Identification) technology, the cartridge also communicates directly with the coffee maker to collect information about filter use and activate the appropriate mode. Once exhausted, it alerts the user to ensure optimal effectiveness. The Purest Water for the Best Taste Coffee begins with water. For the great tasting coffee, pure water is essential. The Smart Filter Cartridge removes additives like chlorine, lead, aluminum, and copper that affect smell and flavor, while minerals that are important for health are retained in the water. Essential Water Scale Removal Limescale in coffee boilers forms when heat draws minerals out of the water and bakes them onto the walls of the machine. This creates issues like reduced water flow and shortened unit life. By removing those minerals as well as calcium carbonate, the filter prevents unhygienic buildup. Automatic Filter Detection Using modern RFID technology, the coffee machine communicates with the filter to recognize when a new one is inserted. Before the capacity is met, the machine prompts the user to change the filter. If the filter is not changed, the machine goes into descaling mode. After a certain amount of time, the user is prompted to descale the machine, which can only be done when the filter is removed.
