Pentair Pentek§ C-252SI Series Cartridges are an enhanced version of Pentek CFB-PlusBB Cartridges. They offer the same chlorine taste & odor reduction and the high sediment reduction performance, as well as the added benefit of inhibiting biofilm and microbial build-up.*

C-252SI Series products are modified molded blocks manufactured using our proprietary Fibredyne technology. This technology creates a unique filter media by attaching powdered activated carbon onto a cellulose-free synthetic fiber matrix. The result is a single cartridge that combines the benefits of both a sediment filter and a carbon block into a single cartridge.

Fibredyne carbon block technology also offers up to two times the chlorine taste & odor reduction and dirt holding capacity of traditional blocks.* In addition, this technology will not release fines into the effluent stream due to a unique post-filtration layer that is fused to the carbon/fiber media blend.

C-252SI Series Cartridges are an ideal choice for a wide range of residential, food service, commercial and industrial applications.
