KX MATRIKX CTO Replacement Filters


KX Matrikx CTO Carbon Block Filters 5 micron


The extrusion process allows the production of a carbon block with more carbon, but a lower pressure drop. This enables a CTO filter to deliver extended life while removing sediment, chlorine, taste, odor and organic contaminants from water, aqueous solutions or suspensions. The CTO is also widely used in filtering organic solvents. The CTO is ideal for use in residential and commercial water purification systems, food service, pre and post-RO systems.

The CTO is manufactured from high purity acid-washed activated carbon. Its dirt-holding capacity and absence of carbon fines makes the CTO the filter of choice. A superior carbon block, CTO combines both high performance and integrity with an exceptional cost-to-performance value. As a result, CTO virtually renders GAC filters obsolete by comparison.

KX MATRIKX CTO filters are the most widely used carbon block devices in the world and provide previously unattainable performance at the lowest price point. CTO filters simultaneously remove free chlorine and organic chemicals that contribute to taste and odor while providing the particulate filtration and dirt-holding capacity of an efficient 5 micron nominal sediment filter. These filters are optimized for applications where they perform the role of both a sediment and activated carbon filter.
