This extruded carbon block design effectively reduces chlorine taste and odor, sediment, and fine particulates from your whole house water supply while maintaining strong flow rates throughout your home’s plumbing system.

Yes, the KX MATRIKX CTO2 HD10 carbon block filter is certified to NSF/ANSI Standard 42 for aesthetic effects, including chlorine, taste, and odor reduction. It is also manufactured from FDA-compliant materials, making it a trusted choice for whole house filtration where safe, certified performance is a priority.

The KX MATRIKX CTO2 HD10 has a rated capacity of approximately 20,000 gallons or 6 months of use, whichever comes first, under typical whole house conditions. Replacement intervals may be shorter in homes with heavily chlorinated municipal water or high daily water consumption. Monitoring for drops in flow or returning chlorine taste is the best indicator it’s time to replace the cartridge.

The MATRIKX CTO2 HD10 is a Big Blue–style cartridge with dimensions of 9-3/4" in length and 4-1/2" in outer diameter. It fits standard 10" Big Blue whole house housings from most major manufacturers, making it an easy drop-in upgrade for existing whole house carbon block filtration systems.

The MATRIKX CTO2 HD10 uses KX Industries’ proprietary extruded carbon block technology to reduce chlorine taste and odor, sediment, rust, silt, and fine particulates down to 10 microns. The high-purity activated carbon block structure delivers consistent contaminant reduction throughout the filter’s service life without channeling or bypass, providing cleaner, better-tasting water at every tap in your home.
