Pentair Pentek DGD-5005-20 Big Blue 20-Inch Sediment Filter Cartridge, 5 Micron

Upgrade your Big Blue filtration with the Pentair Pentek DGD-5005-20 cartridge. Crafted from 100% pure polypropylene, it is designed for use in Pentair Pentek Big Blue filter housings. The cartridge is engineered to remove dirt, sand, silt, and particulates without imparting taste, odor, or color to your water, while offering strong chemical resistance.

The DGD design emphasizes an efficient flow path, delivering filtration closer to the cartridge center. This structure supports up to three times the dirt-holding capacity of similarly sized sediment cartridges and can outperform standard spun or string-wound variants. The larger diameter helps reduce the particle load, enabling higher flow velocities, while the deeper effective filter depth enhances particulate reduction and loading capacity.

Ideal for a range of settings, the DGD-5005-20 is sized for all 20-inch Big Blue housings (and other heavy-duty housings) and can replace any 20" x 4.5" sediment cartridge. The cartridge blends straightforward replacement with consistent performance, supporting water quality across residential, rural, municipal, and small commercial applications.
