Pentair Pentek EPM Series Cartridges are a modified version of our EP Series Cartridge. An economical price makes this cartridge suitable for taste, odor and chlorine taste & odor reduction, as well as sediment filtration. EPM Series Cartridges are manufactured using a process that yields a cartridge with a nominal 10 filtration rating, high porosity and chlorine taste & odor reduction. The high porosity design helps the cartridge from plugging before its adsorption capability is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. These cartridges are protected by an outer wrap designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges.
