Watts (MAXCL-975) 10"x2.5" C-MAX Coconut Shell Carbon Block Filters - for Maximum Chlorine Removal

The Watts MAXCL-975 delivers professional-grade chlorine reduction using densified coconut shell carbon block technology in a standard 10"x2.5" format. This 5-micron filter combines aggressive chemical adsorption with effective sediment filtration, making it a versatile choice for both whole-house and reverse osmosis pre-filtration applications.
SPECIFICATIONS

Watts MAXCL-975 Technical Details

Model Number MAXCL-975 (also sold as MAXETW-975)
Dimensions 10" x 2.5"
Filtration Rating 5 micron nominal
Carbon Type Coconut shell carbon block
Primary Function Maximum chlorine removal, taste and odor reduction
Compatible Applications RO pre-filtration, whole-house systems, point-of-use
Construction Extruded carbon block (no carbon fines release)
Testing Independently verified performance
INSTALLATION & USE

Installing Your Carbon Block Filter

  1. Shut off water supply and relieve system pressure before opening the filter housing.
  2. Remove old cartridge and clean the housing sump with mild soap and water, inspecting the o-ring for any wear or damage.
  3. Insert the Watts MAXCL-975 cartridge into the housing, ensuring it seats properly on the center standpipe.
  4. Hand-tighten the housing cap and slowly turn water supply back on, checking for leaks at the housing seal.
  5. Flush the new carbon filter for 3-5 minutes to purge any air and fine carbon dust from the manufacturing process.
COMPATIBILITY

System Fit and Applications

The Watts MAXCL-975 fits any standard 10-inch filter housing with 2.5-inch inner diameter, including most Watts, Pentek, Culligan, and GE housings. It works equally well as RO pre-filtration (protecting membranes from chlorine damage), in whole-house configurations for citywater treatment, or as a point-of-use cartridge for taste and odor improvement. The 5-micron rating also provides sediment filtration, making this a dual-purpose cartridge that can replace separate sediment and carbon stages in space-constrained installations.

🔧 Pro tip: Carbon block filters are directional. Install with water flow entering from the outside of the cartridge toward the center core. Most cartridges have molded arrows indicating proper flow direction—if yours doesn't, water should always flow from the larger outer surface toward the inner standpipe for optimal contact time and capacity.
