Genuine Pentair Pentek® DGD-5005-20 (155358-43) Big Blue Sediment Filter Cartridge

Protect your home's water with the genuine Pentair Pentek® DGD-5005-20 (Part #155358-43) dual-gradient sediment filter cartridge. Designed to reduce sand, silt, rust, and other particulate matter, this 20" Big Blue filter features dual-gradient density construction with a 50-micron outer layer and 5-micron inner core. This design captures larger particles first while trapping finer sediment deeper within the cartridge, providing higher dirt-holding capacity, longer filter life, and reduced pressure drop compared to standard sediment filters.

The Pentair Pentek® DGD-5005-20 fits most standard 20" x 4.5" Big Blue filter housings and is ideal for whole-house residential, commercial, and well water applications. Manufactured from 100% pure polypropylene, it offers excellent chemical resistance and is certified to NSF/ANSI Standard 42. Replace the cartridge regularly based on your water quality and usage to maintain optimal filtration performance. Genuine Pentair Pentek® replacement part 155358-43.
