KX Technologies MATRIKX-CTO2-HD20 MatrikX Whole House Filter Replacement Cartridge
The MATRIKX + CTO2 filters are the most widely used carbon block devices in the world and provide previously unattainable performance at the lowest price point. The dirt-holding capacity and the absence of carbon fines makes the KX-MATRIKX-CTO2-HD20 the filter of choice. A superior carbon block combines both high performance and integrity with an exceptional cost-to-performance value. As a result the KX-MATRIKX-CTO2-HD20 virtually renders GAC filters obsolete by comparison.
