The Model 2001 three-stage filtration system by Keystone Filter Division treats all the water in a home using a series of three filters. The whole house's dirt and sediment removal is provided by the first unit. The second filter offers iron, lead and copper protection. The third unit removes objectionable odors such as chlorine and sulfur. This system can eliminate water stains in bathtubs, showers, sinks and pools without wasting water. Other features include easy-to change filter cartridges, NSF-approved components and FDA-grade materials. Keystone Filter Division, Met-Pro Corp.
