## Overview

The Pentair Pentek DGD-5005-20 Big Blue Water Filter is a 20-inch whole house sediment filter cartridge engineered with a dual-gradient density design for superior particulate reduction. Certified to NSF/ANSI Standard 42, it offers 3X the dirt holding capacity of similar filters, fits all standard 20-inch Big Blue housings, and is made from 100% pure polypropylene for chemical resistance and durability. Ideal for residential and commercial use, it ensures clean, taste- and odor-free water while protecting your plumbing system.

## Description

DGD Series Cartridges are manufactured from 100% pure polypropylene and are sized for use in Pentair Pentek Big Blue Filter Housings. DGD Series Cartridges are designed for purity and will not impart taste, odor or color to the liquid being filtered. Additionally, the polypropylene construction provides superior chemical resistance. The DGD Series' advanced design combines selective final filtration with appropriate pre-filtration to achieve up to three times the dirt holding capacity of similar size sediment cartridges and even greater capacity than standard spun or string-wound cartridges. The larger diameter of the filter reduces the particle load, allowing it to operate at higher velocities. The effective filter depth is increased to a full 233%. This increased depth provides very high particulate reduction efficiencies and added loading capacity. The design and performance characteristics of the DGD Series Cartridges make them an excellent choice for all residential, rural, municipal and commercial applications.
