Pentek - EP-20BB - 20" x 4.5" Carbon-Briquette 5 Micron Filter

The Pentek EP-20BB is a 20" x 4.5" carbon-briquette cartridge that combines the deep reduction power of activated carbon with a nominal 5-micron sediment rating and an Endurawrap pre-filter for extended service life. Rated for 40,000 gallons and designed for whole-house, commercial, and well water systems, it delivers reliable chlorine, taste, and odor removal without sacrificing flow or capacity.

Where This Filter Works

The Pentek EP-20BB is designed for 20-inch Big Blue filter housings and is ideal for whole-house filtration, commercial food service, well water treatment, and any application requiring both sediment reduction and chlorine removal. The Endurawrap pre-filter traps sediment before it can plug the carbon block, making this cartridge especially effective in higher-sediment environments where standard carbon blocks fail prematurely. Use it in residential point-of-entry systems, restaurant ice machines, beverage dispensers, or light industrial settings where taste, odor, and chlorine reduction are priorities alongside dirt-holding capacity.

💧 The EP-20BB's high-porosity design prevents premature plugging, so you actually use the carbon's full adsorption capacity instead of replacing a clogged cartridge with chlorine reduction left on the table.
