## Overview

The Pentair Pentek ECP50-20BB is a 20-inch whole-house sediment filter cartridge featuring a robust 50 micron rating. Its unique resin-impregnated cellulose and polyester pleated media offers 33% more dirt-holding capacity and enhanced strength, ensuring longer life and superior filtration. Designed to fit all standard 20" Big Blue housings, it protects your home’s water system by efficiently removing dirt, sand, and silt while maintaining high flow rates and low pressure drop. Color-coded for easy replacement every 6 months, this NSF-certified cartridge is the smart choice for professional-grade water filtration.

## Description

Pentair Pentek ECP Series Cartridges are manufactured from a special formulation of resin-impregnated cellulose and polyester fibers. This unique blend of materials provides a higher wet strength than regular cellulose cartridges. It also provides high flow rates and dirt-holding capacity while maintaining extremely low pressure drop. The media is pleated around a polypropylene core for added strength. The pleated endcaps of the standard cartridges are immersed in a thermo-setting vinyl plastisol. The Big Blue cartridges have a molded endcap with gaskets. The pleated ends are sealed to the endcap with a thermoplastic adhesive. The overlap seam is sonically welded to reduce internal bypass, improving filtration efficiency. ECP Series Cartridge endcaps feature a color-coding system for easy identification of micron ratings: tan (1 micron), white (5 micron), blue (20 micron), and yellow (50 micron).
