Pentair Pentek ECP5-20BB Big Blue Sediment Water Filter, Whole House Replacement Cartridge, 5 Micron

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. The pleated media is wrapped around a polypropylene core for added strength, and 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, and 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.

The 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). This unique blend of materials also provides high flow rates and dirt-holding capacity while maintaining extremely low pressure drop.

To keep your water clean and protect your appliances, the Pentair Pentek ECP Series Cartridges are designed to remove dirt, sand, silt, and particulates. These cartridges fit all 20" Big Blue housings and can replace any 20" x 4.5" heavy-duty sediment filter cartridge.

With 33% more dirt-holding media than many competitors, the Pentair Pentek ECP Series Cartridges offer a longer lifespan. 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 Pentair Pentek 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 appropriate replacement cartridge.

In summary, the Pentair Pentek ECP Series Cartridges are designed to provide effective water filtration and protection for your home and appliances. Their unique blend of materials, pleated design, and color-coding system make them a reliable and easy-to-use solution for maintaining clean, high-quality water.
