Calgon Carbon AquaKnight 1 Cubic Foot Granular Activated Carbon Water Softener

Granular Activated Carbon constitutes an excellent filtration media, having a high density with a balanced pore-structure for more efficient absorption. Removes the undesirable taste present in many chlorinated water supplies, which is the result of the formation of chlorophenols, often present in raw waters that contained phenols and were subsequently treated with chlorine. Effectively absorbs orthochlorophenol and removes free chlorine from water supplies, providing clean, fresh water with no objectionable taste characteristics.
