More magnesium - more flavor - more power. Thanks to the unique BWT filter technology, your tap water is transformed into premium magnesium mineralized water. The local tap water is freed from disruptive odors and taste substances such as chlorine, lead, or copper. The lime content is reduced while being enriched with the valuable mineral magnesium in ionic form. Magnesium not only supports a more vital and active lifestyle, but it is also an excellent flavor carrier. With magnesium mineralized water, the aroma of tea and coffee is optimally enhanced, and it is also a true delight when enjoyed on its own. The patented BWT magnesium technology replaces a portion of the calcium hardness with valuable magnesium hardness. This way, the physiologically important hardness in the water is maintained while providing ideal lime protection. Your appliances, such as kettles and coffee machines, are reliably protected from limescale buildup. Easy-Fit: perfect ergonomics and slim design fit into all standard refrigerator doors. Easy-Fill: practical and attractive design for effortless filling without splashes. It has a volume of 1.4 liters of filtered water.
