At its lower end, the CLARIS filter cartridge also has a depot with natural active ingredients that stabilize the water in the tank and thus reduce limescale deposits in the area of the tank bottom. This works completely without any additional energy or action, only through the natural movement of the water in the tank, through which it always flows lightly through the depot. As before, the upper part of the CLARIS filter cartridge for coffee preparation filters exactly the amount of water needed for a perfect cup of coffee by means of ion exchange and activated carbon in the upflow principle. The plus for hygiene and cleanliness CLARIS Blue+ supplements the tried-and-tested professional upflow principle, which filters exactly the amount of water required each time coffee is brewed, with a deposit of natural active ingredients. The plus: Due to its natural movement, the water always flows lightly through this depot and is stabilized by the contact. This leads to less limescale deposits and ensures maximum cleanliness in the water tank. Suitable for any kind of tap water Thanks to the innovative formula, the filter cartridges are suitable for any tap water worldwide. The extremely effective granules always filter limescale to the optimum level (even at low water hardness) and reduce harmful and taste-impairing substances such as chlorine more efficiently than ever
