The Pentek DGD-7525-20 Gradient Density Polyspun Sediment Water Filter Cartridge provides true depth filtration for effective sediment reduction in high-capacity water filtration systems.

Its graded-density construction filters water progressively through the cartridge. The outer 25-micron layers capture larger particles, while the finer 10-micron inner layers capture smaller sediment. This design distributes contaminants throughout the filter media rather than collecting them only on the surface, providing excellent dirt-holding capacity and supporting consistent water flow.

Key features:

• True graded-density depth filtration

• Filters progressively from 25 micron to 10 micron

• Captures particles throughout the filter media

• High dirt-holding capacity
