The Pentek UDS-10EX1 is a KDF/GAC combo filter that provides the benefits of two potent filter media's in a single cartridge. It contains 1 pound of KDF 55 combined with granular activated carbon. Together they will reduces chlorine taste and odor, hydrogen sulfide (rotten egg smell) water-soluble heavy metals, and control scale, bacteria, and algae in your water. KDF is a patented medium that consists of high purity copper-zinc alloy granules that use redox (exchange of electrons) to effectively reduce chlorine and heavy metals as well as controlling microorganisms in potable water. KDF is significantly more effective for hydrogen sulfide (rotten egg smell). THIS FILTER SHOULD NOT BE USED IN WHOLE HOUSE APPLICATIONS. Because of it's unique flow structure, the UDS-10EX1 will restrict flow and cause pressure loss in whole house applications. It is best suited for smaller dedicated applications.
