SUBSTITUTE FOR CULLIGAN PROPRIETARY COMPONENTS
Some Culligan filters have a double ''O'' ring at one end and some of their membranes have double ''O'' rings at both ends.
Because of this, we call them ''proprietary'', but we sell filters and membranes which you can substitute in place of the Original Culligan ones.
