Care instructions
The filter cartridge should be replaced regularly after 6 months and no later than 12 months, or earlier when the filter capacity has been reached. The product is not cleaned like a regular coffee filter, and the manufacturer does not provide any special washing or descaling instructions for the cartridge itself. One thing to keep in mind is that the correct replacement interval is crucial if you want to maintain both limescale protection and consistent flavor over time.
Five layers of advanced filtration
We appreciate that BWT has built the system in clear filtration stages where each layer has a practical function. First, larger particles like sand and rust are captured in a pre-filter. Then oxidants are reduced through activated carbon, which also protects the ion exchanger. The high-performance ion exchanger adjusts the mineral balance and reduces hardness-forming substances, while additional carbon filtration helps remove organic compounds, chlorine, odors, and off-flavors. Finally, a fine filter captures small particles and suspended substances before the water reaches your machine.
