Pentek - CFB-PLUS20BB - 20" x 4.5" Fibredyne Modified Carbon Block Filter - 5 Micron
CFB-PLUS20BB 20" x 4.5" Modified Carbon Block Filter
Fibredyne Dual-Action Filtration
Synthetic Fiber Matrix
Water flows through the cellulose-free synthetic fiber structure, capturing sediment, dirt, and particulate down to 5 microns with exceptional dirt-holding capacity.
Bonded Activated Carbon
Powdered activated carbon bonded to the fiber matrix reduces chlorine taste and odor, along with organic contaminants, at twice the capacity of traditional carbon blocks.
Post-Filtration Layer
A fused post-filtration layer prevents carbon fines from entering the effluent stream, ensuring clean, clear water without black residue common in standard carbon blocks.
Technical Details
| Model Number | CFB-PLUS20BB |
| Dimensions | 20" x 4.5" |
