PurePro Alkaline Water Filter Cartridge Works with an Reverse Osmosis Water Filter System – simple push fittings. The PurePro Alkaline filter raises RO water pH and helps to minimise the fluctuations of pH. 100% organic and natural calcium, magnesium, sodium, potassium ions added. Makes the “tinny” tasting RO water taste better and softer. Adding calcium back to the RO water improves the taste of the water, giving the water a much softer feel.
