To enable the filter and coffee machine to communicate, JURA uses modern RFID technology. Any machine fitted with the intelligent water system (I.W.S.®) recognises when a filter is inserted, automatically switches to filter mode and starts the rinsing process. When the filter capacity is nearly used up the machine prompts the user to change the filter. If the filter is not changed, the machine activates descaling mode. After a certain amount of use, the user is prompted to descale the machine. This can only be done when the filter is removed, so there is no more risk of user error resulting from misunderstandings.
* CLEARYL Smart+ was designed for the following machines with the intelligent water system (I.W.S.®):


Coffee contains 98% water. The better the quality of the water, the purer and less adulterated the aroma. The CLEARYL Blue+ filter cartridge reliably filters the water to leave the optimum ingredient for perfect coffee: pure water for pure enjoyment.


The CLEARYL White filter cartridge filters the water before every preparation, ensuring consistently high water quality for the perfect cup of coffee. The CLEARYL White filter cartridge protects the machine against calcium deposits for a longer service life. If you are using a CLEARYL White filter cartridge there is no need to descale the machine.
