Rock Alkaline Filter

The Rock Alkaline filter is one of the natural ways to increase the pH in drinking water. The filter is ideal to be installed on reverse osmosis systems to increase the pH level of clean filtered RO water. When RO passes through this filter, mineral stones continuously release minerals such as calcium, potassium, magnesium, increase antioxidant properties as well as negative oxidation.
