This cartridge removes acidity from your reverse osmosis drinking water by raising the PH from 5.5 to neutral. It also reduces the chlorine and chemicals in your water supply, providing great-tasting water.
Calcite is a crushed and screened white marble media, which can be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. Carbon filters sediment and chemicals such as chlorine. Replace cartridge when rated capacity (750 gallons) is reached or when flow becomes too slow.
