The right water is crucial to the taste of the coffee because coffee consists in fact of 98 % water. In addition to calcium, minerals and fluorides, the tap water in many areas contains traces of lead, copper, aluminium and chlorine. Positioned directly in the water tank, the CLARIS filter freshly filters the water every time coffee is prepared. It completely absorbs harmful substances while retaining important fluorides, which help the flavors to really develop. With the optimum water quality, every cup of coffee becomes a full-bodied taste experience. CLARIS eliminates the need to descale the machine.
