The Everpure 7CC-BW Filter Cartridges are engineered to enhance water hardness by introducing a precise amount of calcium carbonate minerals into low hardness/TDS waters. This controlled mineral addition is perfect for coffee and other applications requiring specific hardness levels for optimal results. Not only does it improve water quality, but it also protects equipment by mitigating the corrosive tendencies of low TDS content waters, ensuring longevity and reliability. Furthermore, it enhances electronic level control sensitivity by increasing water conductivity, optimizing performance in various settings.
