    Product Description


    Size:FA15 Alkaline Filter

    Product Features

    This Alkaline filter for Reverse Osmosis systems is an inline cartridge with mineral balls, calcite media, and corosex. The alkaline filter improves the pH value of the RO water which could be slightly acid after the reverse osmosis process. It also gives back minerals such as ionized calcium and magnesium, which were taken away during the water filtering process. This filter is capable of increasing the pH value of the RO water by 0.5 to 0.8. The Alkaline filter replaces lost minerals from the RO process and restores these minerals back into the pure water. These minerals being restored will slightly increase the TDS value, normally between 10-20 ppm.
