Magnesium makes all the difference!

The BWT Magnesium Mineralizer table water filter works in two stages. The first stage removes the aroma- and taste-inhibiting substances, i.e. chlorine. In the second, heavy metals such as lead and copper are removed and the hardness agent, calcium, is replaced by precious magnesium, thereby protecting domestic appliances against limescale. With this process, the filtered water contains a much higher mineral magnesium content compared to other filtration techniques and provides a unique taste experience.

The core of the BWT Magnesium Mineralizer table water filter is its filter cartridge with patented BWT magnesium technology. The magnesium-enriched drinking water enhances the full aroma of tea and coffee and, with its gourmet taste, is also totally satisfying when drunk on its own. The magnesium gives it a particularly natural, balanced and fresh flavour.

BWT’s patented magnesium technology:



  • A fine filter retains particles

  • The granulate activated carbon removes impurities and the aroma- and taste-inhibiting substances, e.g. chlorine, from the water

  • The ion exchanger removes calcium and heavy metals (if present in the tap water)

  • Precious magnesium is added to the water, using the patented BWT magnesium technology

  • The fine filter prevents the discharge of particles into the filtered water
