At the lower end of the CLARIS filter cartridge, there is a capsule of natural active ingredients that stabilise the water in the tank, reducing limescale deposits at the base of the tank. It functions entirely through the natural movement of water in the tank, which continuously flows gently through the capsule without the need for additional energy or a special mechanism. As before, the upper part of the CLARIS filter cartridge uses ion exchange and active carbon with the up-flow principle to filter exactly the right amount of water for the perfect cup of coffee.

Even better hygiene and cleanliness
CLARIS Pro Blue⁺ enhances the tried-and-tested professional up-flow principle, which filters exactly the amount of water required every time you make a coffee, with the addition of a capsule containing natural active ingredients. And the 'plus'? The natural movement of the water causes it to continuously flow gently through the capsule, stabilising it through contact. The result is less limescale and maximum cleanliness in the water tank.

Suitable for all types of mains water
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 stabilisation 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.
