The Pentek 555469-43 has been discontinued. Please see the Pentek DGD-5005-20 - Gradient 20 Inch Water Filter for a suitable replacement.
The Pentek GD-5010-20BB 20" Big Blue Filter Cartridge has two unique layers that holds up to 3 times more dirt than pleated, string-wound and standard spun polypropylene filter cartridges. With a filtration media made from 100% soft quality polypropylene, the Pentek Big Blue 20" Filter Cartridge provides enhanced purity without affecting taste, odor and color. The polypropylene construction is not prone to attacks from bacteria and provides advanced chemical resistance.
This space saving, all-in-one Big Blue Filter Cartridge eliminates the need for any additional filter canisters. The larger outer pre-filter reduces partial load of the Big Blue GD-5010-20BB to the inner post filter. This filtration process allows the filter cartridge to operate at higher velocities with a lower pressure drop. This cartridge filter is also known as part 555469-43.
