This (carbon block filter) is Tested And Certified by NSF International against NSF/ANSI Standard 42 for material and Structural integgrity requirements.

Premium Granular Activated Carbon Filter Cartridge is made of a highly porous adsorbent material, produced by heating organic matter, such as coal, wood and coconut shell, in the absence of air, which is then crushed into granules. Activated carbon is positively charged and therefore able to remove negative ions from the water such as ozone, chlorine, fluorides and dissolved organic solutes by absorption onto activated carbon. Universal Industry Standard size of 20” by 4.5” and is compatible with most industry standard Big Blue Filter units.
