## Overview

The Pentair Pentek EP-20BB is a 20-inch whole house carbon block water filter cartridge featuring bonded powdered activated carbon for superior chlorine taste and odor reduction. Designed to fit all standard 20" Big Blue housings, it boasts a high porosity structure to prevent clogging and maximize adsorption capacity. NSF certified and capable of filtering up to 44,000 gallons, this cartridge ensures a full year of clean, fresh water for residential and 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 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 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

## Questions & Answers

**Q: where is it made?**
A: This product is made in the USA.

**Q: when it says "reduces . . . chlorine taste" does this mean it removes chlorine from water or just alters it in some way that you don't taste it?**
A: No carbon will remove the chlorine may not be 100% but you will definitely tell a difference if chlorine is all your dealing with then no need for a 5mic carbon go just carbon it's cheaper if you ever decide you want a water softener it's best to remove the chlorine first... But a great 1x20 filter

**Q: Does it fit inside 10filter housing**
A: I assume you are asking if this cartridge fits in the shorter "big blue" filter housing ... While its actually closer to 13"×7" they refer to it by average filter size which is 10"×4.5". That's a really good question since nowhere does it state which housing to use with it. Dimensions shown for this cartridge are 4.6"×4.6"×9.8". Dimensions for the Big Blue® housing are approx 7.25"×7.25"×13" and calling for a filter approximately 4.5"×10".  This is the housing and filter combination that I use. The cartridge fits snugly and allows proper water flow in that housing.

**Q: Our municipal water in San Francisco is pretty clean, how long before this filter cartridge is recommended for replacement?**
A: This cartridge is rated for 6,000 gallons.  If kitchen sink only, should provide drinking water for a year.  If whole house, run 2 in parralel to get needed flow, the pair might last 3 months.
