Pentek FloPlus-10BB 0.5-Micron Big Blue Carbon Water Filter – 10" x 4.5" Whole-House Cartridge

Enhance your home water with the Pentek FloPlus-10BB

Experience practical filtration that supports cleaner, clearer water at every faucet. The FloPlus-10BB is designed for whole-house use, delivering a refined balance of high efficiency and steady flow. Its compact 10" x 4.5" cartridge fits into standard Big Blue housings, making it a versatile upgrade for homes that want better taste, odor control, and small-particle filtration without frequent service calls.

How it works

This cartridge blends premium filtration media to reduce chlorine taste and odor while targeting very small particles. It achieves flow characteristics similar to a 10-micron carbon block, yet offers the particulate efficiency of a finer 0.5-micron cartridge. The result is water that feels crisper and more consistent across daily use, with a filtration profile designed to minimize pressure drops even in busy households.

Key benefits you may notice

• Noticeable improvement in taste and odor from chlorine-related flavors.
• Removal of very small particles that contribute to water clarity and overall filtration performance.
• High flow rates paired with a low pressure drop help maintain steady water pressure in multi-user homes.
• Compatible with all 10" Big Blue housings and suitable as a replacement for standard 10" x 4.5" carbon cartridges.
• NSF international tested and certified for filtration reliability.
• Up to 25,000 gallons of capacity, with typical replacement cadence around six months or when pressure or quality shifts.

Compatibility, installation, and maintenance

Designed for straightforward use in common filtration setups, the FloPlus-10BB is easy to integrate with existing 10" Big Blue housings. Ensure proper seals, follow standard orientation, and monitor for changes in flow or water quality over time. Regular cartridge replacement helps sustain filtration performance and system efficiency.

Important notes

• Targeted at small-particle reduction within a household filtration system; not a medical claim.
• Respect the 25,000-gallon capacity guideline and replace the cartridge when you observe reduced flow or quality.
