## Overview

The Pentair Pentek ECP5-20BB is a 20-inch whole house sediment filter cartridge featuring a pleated cellulose-polyester blend that offers 33% more dirt-holding capacity than competitors. Designed for heavy-duty use, it fits all standard 20" Big Blue housings and ensures high flow rates with low pressure drop. Its color-coded end-cap simplifies replacement every 6 months, making it a reliable choice for maintaining clean, particulate-free water throughout your home.

## 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).

- KEEP YOUR WATER CLEAN and protect your appliances by removing dirt, sand, silt and particulates
- FITS ALL 20" Big Blue housings or other 20" heavy duty housings and can replace any 20" x 4.5" heavy duty sediment filter cartridge

- REPLACE EVERY 6 MONTHS or when you notice a drop in water pressure or quality. The cap is color-coded for easy replacement

### ⭐⭐⭐⭐⭐ Works as advertised.
*by N***T on April 8, 2025*

It is what it is advertised as.

### ⭐⭐⭐⭐⭐ Good pre-filter
*by M***N on March 4, 2025*

For my well water, great pre-filter

### ⭐⭐⭐⭐⭐ Good filter for wells
*by A***S on May 9, 2024*

Unlike some comments, the Pentair, Pentek ECP1-20BB 1-Micorn filter does not come packaged with notations not to use with non-chlorinated water. We use it on our well and even with just pressure tank pressure (Less than most city supplied water), it works superbly. Will buy again. PS: We have a professional well company who also recommends this filter.
