The Pentek EP-BB is a nominal 5 micron Carbon block drinking water filter cartridge. The EP-BB filters produce healthier, better-tasting drinking water. The Pentek EP-BB replacement filters high dirt-holding capacity maximizes utilization of the carbon block (based on manufacturer's internal testing). Pentek EP-BB water filters are highly effective at bad taste & odor and chlorine reduction (based on manufacturer's internal testing). The EP-BB water filter cartridges are versatile and combine the long life of carbon block filtration with the higher dirt-holding capacity of wound, carbon-impregnated paper cartridges. The Ametek EP-BB replacement cartridges are manufactured using a patented process designed to help prevent the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. Each filter is protected by Endurawrap™, a uniquely formulated polyolefin bilaminate pre-filter, designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges. The Pentek EPBB filter cartridges are manufactured entirely from FDA-compliant materials making them an ideal choice for a wide range of residential, food service, commercial and industrial applications.
