The Pentek, Ametek, US Filter DGD-2501 Dual Gradient Density Filter works as a pre and post filter all in one, eliminating the need for step-down filtration systems in your home. The outer layer of the DGD-2501 is a 25 micron pre-filter that takes out larger sediment, thus reducing the load on the 1 micron inner-layer post filter allowing it to operate more efficiently and consistently.

The pure polypropylene construction of the DGD-2501 makes it resistant to chemicals and corrosion.

The DGD-2501 fits American Plumber housings W10-PR, HD950, W15-PR and other heavy duty filter housings. Filter life varies depending on usage and water quality.

•  has a 25 micron pre-filter fine sediment water filter layer and a 1 micron post-filter extra-fine sediment water filter layer.
•  larger diameter of the pre-filter reduces the particle load to the post filter, allowing it to operate at higher velocities. The effective DGD-2501 filter depth is increased to a full 233% of standard spun-polypropylene or string-wound filters. This increased depth provides for very high particulate reduction efficiencies and added loading capacity.
• reduce the need for multiple housing step-down filtration systems.
• reduces extra-fine dirt, sand, sediment, silt, rust particles, and scale particles.
• pure polypropylene construction resistant to chemicals and corrosion.
• are designed for purity, bacteria resistance, and chemical resistance.
• will not add taste, odor, or color to the liquid being filtered.
• has three times the dirt-holding capacity of similar sized sediment water filter cartridges.
• is ideal for all residential, rural, commercial, industrial, and municipal applications.
