Watts (WCBCS975) 9.75" X 2.75" Carbon Block 5 Micron

The Watts WCBCS975 is a 9.75" x 2.75" carbon block filter cartridge engineered from 100% coconut shell carbon to deliver up to 99% chlorine reduction at 5 micron filtration. This thick-wall carbon block construction outperforms standard granular activated carbon (GAC) with superior chlorine removal, no channeling, and lower pressure drop across residential and light commercial applications.

INSTALLATION & USE

Cartridge Installation

  1. Shut off water supply and relieve system pressure by opening a downstream faucet or pressing the pressure release button on your filter housing
  2. Unscrew the filter housing sump, remove the old cartridge, and clean the housing interior and o-ring with fresh water
  3. Insert the new Watts WCBCS975 cartridge into the housing, ensuring it seats properly on the center standpipe
  4. Reinstall the sump, hand-tighten firmly, restore water supply, and flush the new cartridge for 5 minutes before use
COMPATIBILITY

System Compatibility

The Watts WCBCS975 fits all standard 10-inch filter housings designed for 2.5" diameter cartridges, including reverse osmosis pre-filtration stages, whole house filter systems, and under-sink filtration units. The media wrap between the center tube and carbon block reduces carbon fines and prevents bypass channeling common in granular activated carbon filters. This cartridge is ideal for municipal water sources requiring chlorine, taste, odor, and sediment reduction. Note: This product cannot be sold or shipped to California or Virginia due to state regulations. For those states, use Watts F109009 as a direct substitute.

🔧 Pro Tip: Carbon block filters perform best when installed after a sediment pre-filter (1-5 micron) to extend cartridge life and prevent premature clogging from heavy particulate loads. Replace every 6-12 months depending on water quality and usage volume.
