The Shower Filter was a snap to install also. There, all we need were a pair of pliers.  The filter is a dual stage system. We were doing research on this and really weren’t aware of how chlorine that you absorb through your skin can effect you health wise. It came with a hand-held massager so that when the grandkids are over I can give them baths and rinse off their bodies with the hand held extension.  I think we made some pretty good choices and by buying the two together we got a great deal. Can’t beat that!
