## Overview

The Pentair Pentek DGD-2501-20 Big Blue Water Filter is a 20-inch dual-gradient density sediment cartridge designed for whole-house filtration. Made from 100% pure polypropylene, it delivers ultra-fine 1-micron filtration with 3X the dirt holding capacity of standard filters. Certified to NSF/ANSI Standard 42, it ensures clean, taste- and odor-free water while protecting your appliances. Ideal for high-flow systems, it fits all 20-inch Big Blue housings and should be replaced every 6 months for optimal performance.

## 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.

Review: Works very well. I will buy it again. - The filter worked very well. The city did some water pipe repairs locally and mud came down the line. The filter was replaced by a plumber after only 3 days. A simple white filter was covered with dirt. The water quality in the house remained excellent. It saved a lot of money replacing fixtures etc.
Review: Recommend using - These work well and we will buy them again.
