The CLARIS Smart+ Filter utilizes the proven professional up-flow principle to filter the precise amount of water necessary for each coffee, now with added natural active ingredients in a convenient capsule. The gentle flow of water through the capsule naturally stabilizes and minimizes limescale buildup in the water tank, ensuring maximum cleanliness.

Thanks to the innovative formula, the filter cartridges are suitable for mains water anywhere in the world. The highly effective granule constantly filters calcium carbonate to an optimum level (even when the water hardness is low) and reduces the level of harmful and flavour-impairing substances, such as chlorine, more efficiently than ever before. It retains important minerals, which help to carry the flavour. The optimum stabilization of the calcium carbonate level in the water tank, combined with efficient filtration when a coffee is prepared, ensures optimum hygiene and water quality for the perfect coffee aroma.
