Pure water for exquisite coffee
CLARIS Smart works according to the professional up-flow principle and always filters exactly the amount of water required for each preparation. This makes efficient use of the filter. Standing pre-filtered water is never left in the water tank, where it could quickly become unhygienic. As well as limescale, it filters out heavy metals and substances that impair smell and taste, such as chlorine. Minerals that are important for health are retained in the water. The result: pure water for perfect speciality coffees and optimum protection against limescale inside the coffee machine.

Automatic filter detection
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.
