Omnifilter CB-5 Carbon Block Cartridge specifications:
Carbon block water filter cartridges trap particulates for cleaner, better tasting water. The type and amount of waterborne contaminants trapped in your carbon block filter is dependant upon the pore size of your filter. The smaller the pore size, the more contaminants and particles get trapped.
