## Overview

The Pentair Pentek EPM-20BB is a 20-inch whole house carbon block water filter cartridge designed to reduce chlorine, taste, odor, and sediment. Featuring a high porosity design for low pressure drop and a 30,000-gallon capacity, it fits all standard 20" Big Blue housings. NSF and FDA certified, this economical filter ensures long-lasting, reliable water purification with easy maintenance every six months.

## Description

Pentair Pentek EPM Series Cartridges are a modified version of our EP Series Cartridge. An economical price makes this cartridge suitable for taste, odor and chlorine taste & odor reduction, as well as sediment filtration. EPM Series Cartridges are manufactured using a process that yields a cartridge with a nominal 10 filtration rating, high porosity and chlorine taste & odor reduction. The high porosity design helps the cartridge from plugging before its adsorption capability is exhausted, maximizing the utilization of the carbon while maintaining low pressure drop. These cartridges are protected by an outer wrap designed to significantly increase the useful life of the cartridge by trapping sediment that typically plugs carbon block cartridges.
