Matrikx CTO Carbon Block Filter Cartridge (WIDE)



Matrikx CTO 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 capacity and kinetic dynamics.
