Care instructions
We recommend replacing the filter cartridge regularly after 6 months, and at the latest after 12 months or when the filter capacity has been reached. This is important even if you have not exceeded the maximum water volume. One thing to keep in mind is that this is not a filter to be washed or descaled for reuse; it is a replacement cartridge that is changed when its lifespan is over.
About the manufacturer
Behind the filter is BWT, Best Water Technology, an Austrian company headquartered in Mondsee. We appreciate BWT for their clear focus on water quality, scale protection, and sensory improvement in beverages. For those who take espresso seriously, water is not a peripheral detail but a central part of the result in the cup.
If you want to protect your machine and at the same time get better flavor in every brew, this is a well-developed choice for a more consistent coffee experience.
