CFB Series

Pentair Pentek CFB Series cartridges provide the effective chlorine taste & odor reduction found in traditional carbon block media while offering excellent sediment reduction capabilities.

CFB Series products are a modified molded block created by use of 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's 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 carbon/fiber media blend.

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