PURE-PRO RS300PH Alkaline Replacement Filters | pH Mineral Filters for Reverse Osmosis Water Systems The PURE-PRO RS300PH Alkaline Replacement Filters are designed to enhance and remineralize water purified through reverse osmosis (RO) systems. These filters use a multi-mineral blend that adds essential minerals such as calcium, magnesium, potassium, and sodium, restoring natural balance and improving both taste and pH. The result is clean, healthy, and slightly alkaline water — ideal for hydration and everyday consumption. The RS300PH filters not only enhance water quality but also stabilize the pH to a natural level (around 8.0–9.5), reducing acidity and providing a refreshing, crisp flavor. They are compatible with ERS PURE-PRO Series or RS4000 under-sink systems and can be installed easily as the final polishing stage.
