AquaClean Filter

Water is a key element for a good espresso coffee.
Therefore, it should always be filtered in a professional
manner. The AquaClean filter is designed to reduce
limescale build-up inside the coffee machine and to provide
filtered water in order to preserve the coffee aroma and
flavour in each cup. By using the series of 8 AquaClean
filters as indicated in this user manual, you will not need to
descale the machine for the next 5000 cups (with 100-ml
capacity). This filter is easy to use and its sophisticated
technology is effective in preventing limescale build-up.
This way, water will always be perfect and will give a much
more intense aroma to your espresso coffee.
