What are Dual Gradient Spun Poly Depth Filter Cartridges?

Dual Gradient Density Filters work as a pre and post filter all in one, eliminating the need for step-down filtration systems in your home. The outer layer has large pores and a higher micron rated pre-filter that takes out larger sediment. This enhances the dirt-holding capacity, thus reducing the load on the lower micron rated inner-layer post filter. This filter stops particles larger than the inner layer and nominal micron rating of the cartridge allowing it to operate more effectively than surface filtration cartridges.

Benefits of the Dual Gradient Spun-Poly Depth Filter are:

The pure polypropylene construction makes it resistant to chemicals and corrosion
Will not add taste, odor, or color to the liquid being filtered
Designed for purity, bacteria resistance, and chemical resistance
Reduces extra-fine dirt, sand, sediment, silt, rust particles, and scale particles
Three times the dirt-holding capacity of similar sized sediment water filter cartridges
Ideal for all residential, rural, commercial, industrial, and municipal applications
Fits industry standard Giant or Big Blue/Big Clear Housings such as American Plumber, Aqua-Pure, Culligan, Pentek, and Ametek
