## Overview

The Pentair Pentek ECP20-20BB is a 20-inch whole-house sediment filter cartridge featuring a unique resin-impregnated cellulose and polyester pleated design. It offers 20-micron filtration with 33% more dirt-holding capacity than competitors, fits all standard 20" Big Blue housings, and ensures long-lasting, high-flow filtration with minimal pressure drop. Color-coded end-caps simplify maintenance, making it a trusted choice for heavy-duty water filtration systems.

## 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).

Review: Quality filter for a rainwater filtration system. - I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times. They hold together well and filter the water exactly as they should. As long they make them I'll continue to use them.
Review: Good filter for wells - 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.
