Upgrade your whole house filtration with the Pentek EPM-20BB modified epsilon carbon block cartridge (Item #155783-43). Sized for standard 20" Big Blue filter housings, this economically priced cartridge is a modified version of Pentek's EP Series, engineered with a nominal 10-micron filtration rating that delivers effective taste, odor, and chlorine taste and odor reduction alongside sediment filtration.

Manufactured using a patented high-porosity process, the EPM-20BB helps prevent premature plugging before the carbon's adsorption capacity is exhausted, maximizing carbon utilization while maintaining low pressure drop — giving it the highest carbon block dirt-holding capacity in its class for maximum cartridge life. It's further protected by Endurawrap, a uniquely formulated polyolefin bilaminate pre-filter that traps sediment before it can plug the carbon block, significantly extending useful cartridge life.

Rated for 30,000 gallons of chlorine removal capacity at 4 GPM with a 4.0 psi pressure drop, the EPM-20BB is manufactured entirely from FDA-compliant materials, making it a reliable, economical choice for residential, food service, commercial, and industrial applications where dependable whole house chlorine and sediment reduction is needed.
