## Overview

The Pentair Pentek EP-BB Big Blue Carbon Water Filter is a 10-inch whole house replacement cartridge featuring a bonded powdered activated carbon block with a 5-micron filtration rating. Designed for universal compatibility with all 10" Big Blue housings, it offers a high porosity structure to prevent clogging and maximize lifespan, certified by NSF for reliable chlorine taste and odor reduction. Each pack includes 4 cartridges, delivering up to 22,000 gallons of clean water per cartridge, ideal 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.

Review: These filters work flawlessly. - I have been ordering the Pentair Pentek EP-10 Carbon Water Filter, 10-Inch .5 micron for a few years. This product performs as expected and has a consistent performance time range that I appreciate. I've come to be able to install them fairly easily and I change them without excessive effort! Thank you for a great product and the confidence of keeping my water system clean & clear of minerals & contaminants.
Review: Great filters and great price - These filters were quite similar to the ones installed by Culligan. Quality seems great, it’s easy to install yourself, and the water flow issue was resolved by replacing old filter by this filter brand.

### ⭐⭐⭐⭐⭐ Gets the job done
*by D***R on March 16, 2012*

I get municipal drinking water with 1-2ppm of of chlorine (as much as a public pool) and 22 grains of hardness (more than 2x what's considered "extremely hard"). When I had a water softener installed in my house, I also had a Pentek 20" Big Blue Housing installed before softener. I wanted the carbon filter for a few reasons: 1) Keep chlorine out of the shower and bath, out of my family's lungs and off of our skin 2) Keep chlorine out of the washing machine where it bleaches our clothing 3) Protect the resin in the water softener, which should double it's life 4) Protect the plumbing (PEX pipes, rubber in fixtures, etc...) from chlorine 5) Remove the small amount of sediment that is in the city water which collects in valves and fixtures I previously used the Pentek RFC20-BB Radial-Flow Granular Activated Carbon Cartridge . In comparison, this filter is less expensive, has a finer sediment filter (5 micron vs. 25 micron) and it's rated for up to 180F. Also, carbon block filters don't have the same channeling issues as GAC filters, which become less effective at higher flow rates. However, compared to the RFC20-BB this filter can't handle as much water (only 40,000 Gal. vs. 70,000 Gal.) and has a bigger pressure drop (5.5 psi @ 5 gpm vs. 0.9 psi @ 4 gpm). Neither of those were a big concern for me. We use less than 1,000 gal/week so the capacity easily exceeds the 6 month replacement cycle. As for water pressure, I get a solid 60+ psi coming into my house and even a 10 psi drop is not noticeable. If you already have pressure issues, get RFC20 instead.
