KX Technologies operates globally, supplying high volumes of filters and specialty media to equipment manufacturers across multiple markets. KX Technologies is part of Marmon Water, a division of Marmon Holdings, which is in turn owned by Berkshire Hathaway. This corporate backing provides stability and resources for continued research and development. The company holds numerous patents related to carbon block extrusion, filter design, and microbiological filtration claims. Over its more than 30-year history, KX Technologies has achieved several industry firsts, including the first extruded activated carbon block filter, the first refrigerator cassette water filter, the first installed refrigerator air/odor filter, the first cassette water cooler filter, the first OEM point-of-use water filter with microbiological health claims, and the first refrigerator water filter with microbiological health claims. These innovations have positioned KX Technologies as a key supplier in the global water filtration industry.
