Pentair Pentek ECP5-20BB Big Blue Sediment Water Filter

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).

These cartridges are designed to keep your water clean and protect your appliances by removing dirt, sand, silt, and particulates. They fit all 20" Big Blue housings and can replace any 20" x 4.5" heavy-duty sediment filter cartridge.

The Pentair Pentek ECP Series Cartridges offer a longer life with 33% more dirt-holding media than many competitors. They are also stronger than standard cellulose cartridges, thanks to their unique blend of resin-impregnated cellulose and polyester.

It is recommended to replace the ECP Series Cartridges every 6 months or when you notice a drop in water pressure or quality. The color-coded cap makes it easy to identify the correct replacement cartridge.
