## Overview

The Pentair Pentek DGD-2501-20 Big Blue Water Filter is a 20-inch whole-house sediment cartridge featuring advanced dual-gradient density spun polypropylene filtration. Certified to NSF/ANSI Standard 42, it delivers ultra-fine 1 micron filtration with 3X the dirt holding capacity of typical sediment filters. Designed for all 20-inch Big Blue housings, it ensures pure, taste-free water while protecting your appliances. Ideal for residential and commercial use, it requires replacement 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: Great filter - Cleans up the water.
Review: Works as expected - I forgot to replace my filter for a year and well I needed a replacement. This looked exactly like the filter I used for last time so I bought it. Installed it and it working as expected. No problems as Its the correct size. Will buy again in 6 months. This time not forgetting to replace it for a year. Changing a water filter sucks when you have no water to clean the housing. Lesson Learned and will have a bucket of water for cleaning. Also not replacing during a freezing winter can help also.
