KX MATRIKX Pb1 Lead, VOC, Cyst, Chlorine Taste & Odor Filter The KX MATRIKX Pb1 is a powerful, multifunctional filter cartridge for residential and commercial water treatment, providing exceptional lead and cyst reduction (including Cryptosporidium, Giardia, Entamoeba and Toxoplasma). KX MATRIKX Pb1 activated carbon block filters reduce soluble lead using an ion-exchange ­filter medium with high specifi­city for soluble lead. Particulate ­filtration is used to intercept insoluble lead-containing particles. Manufactured with KX’s proprietary extrusion process, MATRIKX Pb1 fi­lters offer high levels of chemical reduction in potable drinking water, including chlorine taste and odor. KX MATRIKX 06-250-20-GREEN is the factory recommended direct replacement for 06-250-125-20, which has been discontinued by the manufacturer and is no longer available.
