## Overview

The Pentair Pentek DGD-7525-20 Big Blue Water Filter is a 20-inch whole house sediment cartridge featuring dual-gradient density spun polypropylene for superior filtration. Certified to NSF/ANSI Standard 42, it removes dirt, sand, silt, and particulates without affecting water taste or odor. Designed for high flow and 3X dirt holding capacity, it fits all standard 20-inch Big Blue housings and is recommended for replacement every 6 months to maintain optimal water quality and appliance protection.

## 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.

## Features

- KEEP YOUR WATER CLEAN and protect your appliances by removing dirt, sand, silt and particulates. DGD Big Blue water filter cartridges are designed for purity and will NOT impart taste, odor or color to your water
- IDEAL HIGH-FLOW PRE-FILTER. Filter density increases toward the cartridge's center resulting in superior particulate reduction and 3X the dirt holding capacity of similar size sediment cartridges
- TESTED AND CERTIFIED BY NSF INTERNATIONAL to NSF/ANSI Standard 42 for your peace of mind. Manufactured with 100% pure polypropylene
- SIZED FOR USE IN ALL 20 inch Big Blue filter housings (or other heavy duty filter housings) and can replace any 20 inch x 4.5 inch sediment filter cartridge
- REPLACE EVERY 6 MONTHS or when you notice a drop in water pressure or water quality for best results and performance

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works very well. I will buy it again.
*by L***E on June 13, 2025*

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.

### ⭐⭐⭐⭐⭐ Get it!
*by B***A on June 1, 2025*

Great replacement filter! Half the price of store unit. Will re purchase going foward.

### ⭐⭐⭐⭐⭐ Gotta change it regularly, but it works!
*by R***Y on April 16, 2025*

Excellent product. Removes sediment as it should. Tip: keep an eye on the price - it often comes down quite a bit -- then buy 'em. It'll go back up again.
