Pentek - CFB-PLUS10BB - 10" x 4.5" Fibredyne Modified Carbon Block Filter - 5 Micron
CFB-PLUS10BB Fibredyne Modified Carbon Block Filter
10" x 4.5" dual-action filtration combining sediment removal with enhanced carbon block performance in a single 5 micron cartridge. Proprietary Fibredyne technology bonds powdered activated carbon to synthetic fiber for twice the chlorine reduction of traditional blocks.
Fibredyne Technology Delivers Dual Filtration in One Cartridge
Bonded Carbon Matrix
Powdered activated carbon is permanently attached to a cellulose-free synthetic fiber matrix, creating a modified block that functions as both sediment and carbon filter without separating or releasing fines.
2x Chlorine Reduction
Fibredyne technology provides up to twice the chlorine taste and odor reduction compared to traditional carbon blocks, with superior dirt-holding capacity throughout the cartridge life.
Highest Sediment Capacity
The synthetic fiber matrix delivers the highest sediment reduction available in a carbon cartridge, capturing particulate while maintaining flow and carbon contact time.
Post-Filtration Layer
A fused post-filtration layer prevents carbon fines from entering the effluent stream, ensuring clean water without the black dust common in standard carbon blocks.
FDA-Compliant Materials
Manufactured entirely from FDA-compliant materials suitable for residential, food service, commercial, and industrial applications where material safety is required.
Pentek CFB-PLUS10BB Technical Details
| Model Number | CFB-PLUS10BB (255677-43) |
| Dimensions | 10" x 4.5" (Big Blue) |
| Micron Rating | 5 Micron |
| Filter Type | Modified Carbon Block (Fibredyne) |
| Technology | Carbon-bonded synthetic fiber matrix |
| Material Compliance | FDA-compliant materials |
| Primary Reduction | Chlorine taste, odor, sediment |
| Applications | Whole-house, well water, commercial |
Housing Requirements
The Pentek CFB-PLUS10BB fits all standard 10" x 4.5" Big Blue filter housings. Compatible with Pentek, Culligan, GE, and other manufacturers' housings designed for 10-inch Big Blue cartridges with 4.5" diameter. Verify housing O-ring condition before installation to ensure proper seal.
Replacement Schedule
Residential Whole-House
Replace every 3 to 6 months depending on water usage and chlorine levels. Monitor pressure drop and taste changes as indicators for replacement.
Well Water Applications
Replace every 2 to 4 months when treating well water with elevated sediment. High particulate loads will reduce cartridge life and require more frequent changes.
Commercial & Food Service
Inspect monthly and replace as needed based on flow rate reduction or when chlorine taste returns. High-volume applications may require monthly replacement.
Dual Filtration
Sediment and carbon in one cartridge
No Carbon Dust
Fused layer prevents fines release
Enhanced Capacity
2x chlorine reduction vs. standard blocks
Wide Application
Residential to industrial use
