Title: Good replacement cartridge
Review: The Everpure replacement cartridge works quite well. It just takes a few tries to install. The critical point is seating the cartridge so that the locking mechanism on the cartridge holder is engaged. Otherwise water will leak. For those like me who are all thumbs, just try a few times until you get it.
