MATRIKX® CTO filters are one of the most widely used carbon block cartridges in the world and provide previously unattainable performance at the lowest price point. MATRIKX® CTO filters simultaneously remove chloramines, free chlorine and organic chemicals that contribute to taste and odor while providing the particulate filtration and dirt-holding capacity of an efficient five-micron nominal sediment filter.*

A superior carbon block, the enhanced MATRIKX® CTO filters combine both high performance and integrity with an unrivaled cost-to-performance value.
