Benefits of KX MATRIKX Extruded Carbon Filters 

  • Chlorine Taste and Odor Reduction as well as Dirt and Sediment Removal: for better tasting drinking water, and protection of downstream equipment.
  • No release of carbon fines: Extruded carbon filters do not release activated carbon paerticles (''gray water'') during startup or operation. Extensive flushing or ''activation'' of extruded filter elements is not required.
  • No channeling, fluidizing, or bypassing: Extruded carbon is a rigid structure that prevents movement of the adsorbent partic;es or the formation of channels and defects in the adsorbent structure.
  • Low pressure drop: Water flows through an extruded filter element in the ''radial'' direction (from the outside of the filter element to the inside). This results in nearly fifteen times more prefiltration suurface area and a much lower flow ''density''.
  • Low binder content and high dirt capacity: Only a small amount of thermoplastic binder is used in the extruction process, about one-half of what is used in a molded carbon block.

About KX MATRIKX Sustainability

 Matrikx® filters 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 nimber og micro-pores and available carbon surface area, which display superior adsorption capacity and kinetic dynamics.
