They use a five-step filtration process to remove even the slightest trace of impurities from the water– while retaining all the important minerals that benefit your health. Beyond guaranteeing an unparalleled taste experience, the filter fulfils another important function: by filtering out limescale, it ensures that your Water System can perform perfectly over its long lifetime.

  • Activated carbon pre-filter: Removes chlorine, certain organic compounds including insecticides and pesticides.
  • High-performance ion exchanger: Removes limescale and metal substances
  • Activated carbon filtration: Bypass water is filtered and purified while keeping essential minerals.
  • Fine filtration: Captures even the finest remaining particles.
