Mineral Stones with nano silver particles reduce bacteria, keep the water fresh, alkaline and mineralised. Tap water is loaded with contaminants and a lack of minerals. When we have filtered the water, we also need to re-mineralise the water. Our Mineral Stones are made from Elvan Stone (Mineral Adamantine Stone) containing more than 70% of Silica (SiO2), which is then pulverised to an appropriate size. They contain Iron, Magnesium, Calcium, Sodium and Potassium which have been shown to increase pH. Our stones are the only type necessary with both the nano silver and mineralised particles within. Mineral stones last for 18-36 months with proper care. See Peter below with more information and care on mineral stones. Mineral Stones can be left loose in the bottom of your filter or kept inside the BPA free container.
