The CRYSTAL QUEST CQE-RC-04046 Faucet Mount Water Filter Cartridge is a 5-stage water filter that is designed to reduce many contaminants from water. In Stages 1 and 5, water passes through pre and post 1 micron filter pads, which reduce suspended particles such as silt, sediment, cyst, sand, rust, dirt, and other undissolved matter. In Stage 2, water passes through granular activated carbon (GAC), which reduces bad tastes and odors, pesticides and chemicals that are linked to cancer risks. In Stage 3, Ion Exchange Resin reduces heavy metals such as lead, copper, aluminum, and water hardness (pH). In Stage 4, water passes through a combination of KDF-55 and KDF 85 to reduce iron, mercury, copper, nickel, chromium, cadmium, aluminum, lead, other dissolved metals and hydrogen sulfide, and prevents growth of bacteria, algae, fungi, scale, and other microorganisms.
- The CRYSTAL QUEST CQE-RC-04046 Faucet Water Filter Cartridge should be replaced every 6 months to 1 year
