KX Technologies manufactures one of the most internationally successful filter cartridges, the KX MATRIKX Extruded Carbon Block cartridge. These filters are optimized for applications where they perform the role of both a sediment and activated carbon filter, and come in several different models for varying uses, such as lead or cysts removal.
KX Technologies was originally formed in 1989 between Exxon Chemical Corporation and KT Corporation as a Limited Partnership. In 2007 Marmon Water LLC acquired the assets of KX Industries, LP, with the business going forward as KX Technologies LLC.
