Description
The Superpure 20 Inch Carbon Block Water Filter Replacement Cartridge is a carbon-based water filter that removes organic material and chlorine from water.
Granular Activated Carbon is carbon that has been treated with oxygen to make it porous, but it has also been broken up into granules to further increase the surface area for chemical bondage to occur. The water passes through the GAC filter, allowing the organic materials and chlorine to effectively bond with the carbon molecules, thus removing these from the water.
