## Overview

The Pentair Pentek EP-20BB Big Blue Carbon Water Filter is a 20-inch whole house replacement cartridge featuring a 5-micron bonded powdered activated carbon block. Designed for superior chlorine taste and odor reduction, it fits all standard 20" Big Blue housings and boasts a high porosity design to prevent clogging. NSF certified and capable of filtering up to 44,000 gallons, this 4-pack ensures a year of clean, fresh water for residential or commercial use.

## Description

Pentair Pentek EP Series Carbon Block Cartridges are manufactured using a process that yields a cartridge with a nominal 5- filtration rating and high dirt-holding capacity. A high porosity design helps the cartridge from plugging before its adsorption capacity is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. These cartridges are protected by 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. EP Series Cartridges make an ideal choice for a wide range of residential, food service, commercial and industrial applications.

## Features

- GREATER CHLORINE TASTE and ODOR REDUCTION than competitive 10 Micron carbon blocks
- FITS ALL 20" Big Blue or other heavy duty housings and can replace any 20" x 4.5" carbon filter cartridge
- HIGH POROSITY DESIGN helps prevent the cartridge from plugging before its adsorption capacity is exhausted
- NSF INTERNATIONAL tested and certified for your peace of mind
- 44,000 GALLON CAPACITY. Replace every year or when you notice a drop in water pressure or water quality
