It also has a longer filter life compared to other similarly sized filter cartridges.

This Pentek filter replacement cartridge uses advanced Fibredyne carbon block technology for up to two times the chlorine taste and odor reduction and dirt holding capacity of standard carbon block filters. It removes or reduces sediment, dirt, sand, rust, and other impurities.
