The flavour and taste of water is affected by the pH value and the amount of calcium, chlorine and minerals. Water containing too many of these elements is considered “hard”, and not enough is “soft”. The ideal range is medium, too soft and the coffee will taste acidic, too hard will result in a bitter-tasting coffee.

Tap water and filtered water have very different tastes, and will impact the taste of coffee.

A water filter lessens limescale deposits, reduces impurities in water and improves the taste of the coffee.

Inserting or replacing a water filter.

A new water filter must be rinsed before it can be used.

More info how to use a water filter with your coffee machine and how to select the appropriate water hardness you will find in the user manual.
