Pentair Pentek DGD-2501-20 Big Blue Whole House Sediment Filter Replacement

The DGD Series Cartridges are manufactured from 100% pure polypropylene and are sized for use in Pentair Pentek Big Blue Filter Housings. These 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 advanced design of the DGD Series Cartridges 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%, which 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. By removing dirt, sand, silt, and particulates, these water filter cartridges help keep your water clean and protect your appliances.

The DGD Big Blue water filter cartridges are an ideal high-flow pre-filter, with the filter density increasing toward the cartridge's center, resulting in superior particulate reduction and three times the dirt holding capacity of similar size sediment cartridges.

These cartridges have been tested and certified by NSF International to NSF/ANSI Standard 42, ensuring your peace of mind. They are manufactured with 100% pure polypropylene and are sized for use in all 20-inch Big Blue filter housings (or other heavy-duty filter housings), allowing them to replace any 20-inch x 4.5-inch sediment filter cartridge.

For best results and performance, it is recommended to replace the DGD Series Cartridges every 6 months or when you notice a drop in water pressure or water quality.
