This listing is for 2 filters. 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 patented process that yields a cartridge with a nominal 10-micron filtration rating, high porosity and chlorine taste & odor reduction. The high porosity design helps prevent 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 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.EPM Series 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.Pentek is the largest brand in the filtration industryPentek is the originator of carbon block production technologyPentek is the largest producer of carbon blocks worldwideModelMaximum DimensionsNominal µm Rating*Initial ΔP @ Flow*Chlorine Capacity @ Flow*EPM-109-3/4" × 2-7/8"10 µm1.5 psid @ 1.0 GPM>3,000 gal @ 1.0 GPMEPM-2020" × 2-7/8"10 µm1.0 psid @ 2.0 GPM>6,000 gal @ 2.0 GPMEPM-BB9-3/4" × 4-5/8"10 µm5.0 psid @ 2.0 GPM15,000 gal @ 2.0 GPMEPM-20BB20" × 4-5/8"10 µm4.0 psid @ 4.0 GPM>30,000 gal @ 4.0 GPM* Based on manufacturer's internal testing.
