Watts (WCBFF975) 10" x 4.5" Big Blue Coconut Carbon Block 5 Micron Filter

The Watts WCBFF975 is a 10" x 4.5" Big Blue coconut shell carbon block filter cartridge that removes up to 99% of chlorine, taste, odor, and sediment at 5 microns. Built with thick-wall carbon construction and 100% coconut shell carbon, this cartridge outperforms standard GAC filters with superior chlorine reduction, lower pressure drop, and no channeling.

Where This Filter Works

The WCBFF975 fits all standard 10" x 4.5" Big Blue filter housings and is ideal for whole-house chlorine reduction, taste and odor improvement, and sediment filtration. This carbon block cartridge is designed for municipal water applications where chlorine, chemical taste, and fine sediment are primary concerns. The thick-wall construction and coconut shell carbon deliver consistent performance over the filter's service life with lower pressure drop than comparable GAC cartridges. Because it uses a true carbon block design rather than loose granular media, it won't channel or create bypass paths that reduce filtration effectiveness.

💧 Pro Tip: Carbon block filters like the WCBFF975 provide better chlorine and taste removal than GAC (granular activated carbon) because water is forced through the dense carbon matrix rather than flowing around loose granules. Replace every 6-12 months depending on water quality and usage.
