Pentek CFB-Plus10BB Fibredyne Carbon Block – 10-inch Big Blue, 5 Micron Filter Cartridge

Enhanced filtration for better tasting water

The Pentek CFB-Plus10BB Fibredyne carbon block cartridge is an upgraded 10-inch filter designed to work in a 10 inch Big Blue housing. It blends sediment protection with carbon block filtration, delivering a streamlined solution that targets taste, odor, and particulates in a single, easy-to-maintain cartridge. The Fibredyne media attaches powdered activated carbon to a synthetic fiber matrix, creating a dense filter layer that works across daily water use without needing separate stages.

Key benefits you may notice

• Up to two times the chlorine taste and odor reduction and dirt-holding capacity compared with traditional carbon blocks.
• Combines sediment filtration and carbon-block performance in one cartridge for simpler maintenance.
• A post-filtration layer fused into the media helps prevent fines from entering the effluent stream.
• NSF International tested and certified, with materials that comply with common residential and commercial needs.
• Impressive capacity of up to 25,000 gallons; typical replacement around six months or sooner if water quality or flow changes.

Fit, installation, and versatile use

• FITS ALL 10-inch Big Blue housings and can replace any 10 x 4.5 inch carbon filter, making it a flexible choice for many existing systems.
• Designed for residential, small commercial, and light industrial applications where consistent filtration matters.

What to expect in daily use

In everyday use, you may notice a fresher taste and aroma in your drinking water and beverages. The cartridge handles sediment alongside carbon-level filtration in a single pass, potentially supporting more consistent water quality with routine maintenance.

Practical considerations

• Typical replacement cadence is six months, or sooner if you observe reduced flow or quality.
• Capacity up to 25,000 gallons, depending on water quality and household demand.
