Filter cartridges for all BWT water filters with magnesium mineralisation. The human body needs around 300 mg of magnesium every day. In special situations, such as stress or physical activity, the requirement can be twice as high. The body cannot produce magnesium itself, which is why the mineral must be supplied daily through food and fluid. BWT's patented Magnesium Mineralised Water technology offers an intelligent and efficient alternative to conventional food supplements in the form of powders, tablets and capsules, where magnesium is usually bound to salts. The Magnesium Mineralised Water filter delivers magnesium to the body in ionic form and through regular water drinking. This is a significant advantage compared to a selective high-dose intake, in which a large part of the excess magnesium is excreted again and additional, unnecessary salts are added to the body.The filter cartridges have an additional, decisive advantage: With BWT Magnesium Mineralised Water, limescale, chlorine, lead and copper are filtered out of your tap water. This means that your drinking water not only tastes better, but your household appliances such as coffee machines, steam cookers and tea makers are also optimally protected from annoying and harmful limescale deposits. Advantages of the filter technology: Optimal appliance protection for household appliances such as coffee machines and kettles: Reduces the limescale content of the water Reduces odour and taste-disturbing substances such as chlorine as well as organic impurities.
