The KX MATRIKX + CTO/2 32-425-125-20 water filter removes chlorine and other organic chemicals that contribute to taste and odor while also providing the sediment filtration and dirt-holding capacity of an efficient 5 micron nominal sediment filter. These KX 32-425-125-20 filters work great where both a sediment and activated carbon filter are needed. The extrusion process allows the production of a carbon block with more carbon, but a lower pressure drop. The KX MATRIKX + CTO/2 32-425-125-20 water filter delivers extended life while removing sediment, chlorine taste and odor and organic contaminants from water, aqueous solutions or suspensions. KX MATRIKX Industries 32-425-125-20 water filters are also widely used in filtering organic solvents. The KX Matrix 32-425-125-20 water filter is ideal for use in residential and commercial water purification systems, food service, pre- and post-RO systems. The KX MATRIKX 32-425-125-20 carbon filter is manufactured from high purity acid-washed activated carbon. The dirt-holding capacity and the absence of carbon fines makes the KX MATRIKX CTO/2 the filter of choice. KX MATRIKX + CTO/2 replacement filter cartridges combine both high performance and integrity with an exceptional cost-to-performance value.
