The 2 gpm under counter high capacity filtration system is certified to remove 99.2% of lead from your water. This high flow system also reduces cysts, chlorine, odor, sand, silt, dirt and rust for safer, better tasting water. Connecting to an existing kitchen or bathroom faucet is simple. The system comes with all parts and tubing required for a standard installation. There is no need to drill holes in the countertop for a second faucet, as this system connects directly to the cold water supply line.
