Your water’s journey

Stage by stage to pure water

Every filtration stage has a clearly defined task. It is how they work together that makes the difference.

  1. I

    Pre-filtration

    A sediment filter catches sand, rust and suspended particles, protecting every stage that follows.

  2. II

    Activated carbon

    Activated carbon binds chlorine, odors and organic compounds – the foundation of great taste.

  3. III

    Reverse osmosis

    The membrane, with its extremely fine pores, separates dissolved substances from the water. The heart of every system.

  4. IV

    Post-filter

    An activated carbon post-filter polishes the water for a clear, neutral taste.

  5. V

    Remineralization

    Calcium and magnesium are added back in a controlled way – for balanced, soft drinking water.
