The GS-10CAL/RO-B Inline Filter Cartridge is a 10" combination filter with Coconut Shell Granular Activated Carbon (GAC) and calcite media. It is best used in various applications to correct low pH levels, polish water, brew better-tasting coffee, tea, or other beverages. As a post filter in many reverse osmosis systems, it reduces sediment, bad taste, odor, and chlorine. The Pentek GS-10CAL/RO filter increases the pH level of water. Calcite is a natural mineral which dissolves in acidic water to raise its pH to neutral.
