Watts 4.5 x 20 Inch KDF and GAC Process Media Filter Cartridge
The Watts KDF/GAC Water Filter is a standard 4.5″ x 20″ Inch water filter cartridge containing Granular Activated Carbon (GAC) and KDF Process Media. KDF (Kinetic Degradation Fluxion) media when combined with carbon is known to kill algae and fungi, control bacteria growth, remove chlorine, pesticides, organic matter, rust, unpleasant taste and odour, hydrogen sulphide, iron, lead, nickel, chromium, cadmium, calcium, mercury and other organic compounds.
The filter is ideal for situations where you need a higher flow rate or have very low water pressure problems.
These filters will fit all standard 4.5 x 20″ filter housings and are recommended for whole house water filtration systems as they can last up to 5 times longer than standard carbon block filters.
