The Pentek DGD-2501-20 replacement dual-gradient density filter is a 2-in-1 that works as both a pre-filter and post-filter, which eliminates the need for step-down filtration systems in your home.

Pentek recommends replacing the DGD-2501-20 every 3 - 6 months for optimal performance and efficiency.
