The Pentek 555476-43 20 Big Blue Filter Cartridge has been replaced with the compatible Pentek GD-2501-20BB and is a gradient density 100% pure polypropylene filter that provides superior purity without affecting color, odor or taste. This 20" Big Blue Cartridge has two unique layers that hold up to three times more dirt than the standard pleated, string-wound and spun polypropylene cartridges. The larger outer pre-filter of this sediment filter reduces the partial load to the inner post filter. This filtration process allows the Big Blue Gradient Density Cartridge to operate at a higher rate of speed, with a lower pressure drop.

This GDA cartridge series captures particles through the entire depth of the filter media. This filtration process is popular with pretreatment applications that help to protect systems like the reverse osmosis systems.
