Pentair Pentek DGD-5005-20 Big Blue 20-Inch Sediment Filter, 5 Micron, Pack of 6

Overview

The Pentair Pentek DGD-5005-20 Big Blue sediment filter is built for 20-inch Big Blue housings and a 4.5 inch diameter cartridge. It uses 100% pure polypropylene, ensuring filtration without imparting taste, odor, or color to your water. The material also offers strong chemical resistance, making it suitable for varied water chemistries and everyday household use.

Designed to balance reliability with performance, the DGD-5005-20 employs a dual gradient density approach. Filtration density increases toward the center, delivering thoughtful pre filtration and a refined final stage that helps manage dirt and particulates more efficiently than standard sediment cartridges.

Key benefits

• 3x dirt holding capacity compared to similar size cartridges, enabling longer runs between changes.
• Higher flow potential without sacrificing filtration clarity thanks to the larger cartridge diameter.
• Central dense filtration helps reduce nuisance particulates while maintaining steady water pressure.
• 100% pure polypropylene composition provides chemical resistance and dependable durability.
• Non imparting of taste, odor or color to your water, supporting a cleaner water experience.
• NSF International tested to NSF/ANSI Standard 42 for independent quality assurance.

Design and performance

With an expanded active depth and a design that promotes efficient dirt capture, the DGD-5005-20 can achieve meaningful particulate reduction across a range of water qualities. The cartridge is engineered to operate at higher velocities, reducing the load on your filtration system while maintaining filtration integrity.

Filtration depth reaches a full 233 percent of conventional designs, which translates to added loading capacity and robust performance in challenging water conditions.

Fitment and usage

This cartridge is sized for all 20 inch Big Blue filter housings and can replace any 20 inch x 4.5 inch sediment filter cartridge. It is a versatile choice for residential, rural, municipal and commercial applications where sediment control matters.

In everyday use, you may notice improved appliance protection, clearer water during faucets and showers, and a smoother filter maintenance routine as a result of higher dirt capture and a steadier flow.

Care and replacement

• Replace every 6 months or when you notice a drop in water pressure or quality for best results.
• Perform routine housing maintenance and handle cartridges with care to preserve filtration integrity.
