The new standard in carbon block filtration


KX Technologies® and Filtrex Technologies®, both Marmon Water/Berkshire Hathaway companies, have teamed up to combine the very best of their MATRIKX® and GREENBLOCK® carbon block lines, into a single world class product offering. The new and improved product line is the result of decades of experience in R&D, design, formulation, and manufacture of high-performance carbon block filters.

MATRIKX® filters, powered by GREENBLOCK®, are made from 100% coconut shell carbon, a renewable, and ecologically sustainable material. The carbon is processed into blocks using a unique binder system and proprietary manufacturing techniques to produce filters with a greater number of micro-pores and available carbon surface area, which display superior adsorption capacity and kinetic dynamics.

The companies are committed to Research and Development to advance filtration technology in an ecologically sound way.
