Overview

The Pentair Pentek DGD-7525 is a dual-gradient density sediment filter designed for whole-house filtration in standard 10 inch Big Blue housings. Built from 100% pure polypropylene, it won’t impart taste, odor, or color to your water while offering dependable chemical compatibility and robust filtration performance.

How it works

The dual-gradient design starts filtration at the outer surface and progressively deepens toward the core. This configuration delivers up to 3X the dirt-holding capacity of similar sized sediment cartridges, while maintaining a low pressure drop for smoother, higher-flow operation.

• Up to 3X dirt-holding capacity compared with similar 10 inch filters
• Less than 1 psi pressure drop at 10 gpm, supporting high-flow performance
• 100% polypropylene construction for dependable chemical compatibility
• Certified to NSF/ANSI Standard 42 for material requirements

Performance & Capacity

With a 25 micron rating, it captures visible particulates such as dirt, sand, silt, and other debris. The increased effective filter depth (233%) helps reduce particulates across a broad range of water qualities, offering a reliable pre-filter option for many systems.
