The Pentair DGD Series Cartridges are designed for use in the Pentair/Pentek Big Blue Filter Housings. These 100% pure polypropylene filters provide superior chemical resistance and stop bacterial attacks. Pentair Dual Gradient Density (DGD) filters will not add taste, odor, or color to the liquid being filtered. These filters can be used in either a pre or post filtration application since they achieve up to 3 times the dirt holding capacity of similar sediment filters. The 155360-43 features a larger diameter, which reduces the particle load allowing it to operate at higher velocities. The increased depth of the DGD Series provides very high particulate reduction efficiencies and added loading capacity.

Ideal For a Variety of Applications. The design and performance characteristics of the DGD Series Cartridges make them an excellent choice for all residential, rural, municipal and commercial applications.All in One Design. The Pentair DGD Series Cartridges are a Dual Gradient Density Filter work as a pre and post filter all in one, eliminating the need for step-down filtration systems in your home.Ensures Your Water is Pure and Clean. The outer layer 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.
