PuriPro Mineral Filter improves the qualities of clean water by adding necessary for proper human development and health minerals, such as Calcium, Magnesium, Sodium, Potassium and others readily found in many natural mineral waters. Mainly installed with RO systems to complement their absolute filtration qualities. The mineralized water after the Mineralized filter has perfectly balanced proportions of minerals necessary for healthy development of the human body. This series of mineral cartridges are designed to raise the pH of influent waters. These cartridges contain sparingly soluble sacrificial medias that are only acted upon by acidic waters. They will have little effect on neutral or alkaline water. Daily absorption of minerals in water doesn't have a major impact on the physiological functions of our body, but it can be a great addition to the regular daily mineral intake with solid foods and supplements.
