The Culligan Water Tower Replacement Pre/Post Carbon Filter is an essential part of your Culligan Water Tower system. In the pre-filter position this carbon block filter protects the more expensive membrane by removing chlorine and other corrosive substances from your water. In the post-filter position it serves as a polishing filter to give you fresh, clean tasting water.
