I like that the 5 micron design is available. The supplier that represents Kinetico in my area only offers 50 microns. The 5 micron cartridge seems to last as long as the 50 micron cartridge, which was a pleasant surprise to me. I have recently completely replaced my system (downhole pump, pressure tanks, pressure switch and piping (except softener) and want to get the best performance without excessive expense.
