Watts (WCB10-CHLORA) 9.75"x2.75" Chloramine Carbon Block 5 Micron Filter

The Watts WCB10-CHLORA is a 9.75" x 2.75" catalytic carbon block filter engineered specifically to tackle chloramines, the disinfectant that standard carbon struggles to remove. Built from coconut shell carbon with enhanced catalytic functionality, this 5 micron filter delivers four times the chloramine reduction capacity of conventional carbon blocks.

Filter Replacement Process

  1. Shut off water supply and relieve pressure by opening the housing's pressure release button or downstream faucet
  2. Unscrew the filter housing using a filter wrench, remove the old cartridge, and clean the housing sump with mild soap
  3. Insert the Watts WCB10-CHLORA cartridge into the housing, ensuring the filter seats properly on the center tube
  4. Replace the o-ring if worn, hand-tighten the housing back onto the cap, and slowly turn water back on while checking for leaks
  5. Flush the new carbon block filter for 3-5 minutes to remove carbon fines before normal use
COMPATIBILITY

Where This Filter Fits

The Watts WCB10-CHLORA fits any standard 10-inch filter housing designed for 2.5-inch diameter cartridges. It works in both whole-house filtration systems and under-sink reverse osmosis pre-filtration stages. This filter is specifically valuable in municipal water systems that use chloramines instead of chlorine for disinfection—common in many urban water districts. The catalytic carbon formulation makes it ideal for RO pre-treatment, ice maker lines, refrigerator filters, and drinking water stations where chloramine removal is critical for taste and to protect downstream RO membranes.

🔧 Pro Tip: Chloramines persist much longer than chlorine in water systems. If you notice a swimming pool smell or taste even after standard carbon filtration, your utility likely uses chloramines—this catalytic carbon block is the solution. Replace every 6-12 months depending on water usage and chloramine levels.
