I BOUGHT A PC1000SYSTEM  ELEVEN YEARS AGO AND INSTALLED IT ON HOME.  WATER NEVER TASTED SO GOOD. NO BAD ODOR, NO CHLORINE SMELL OR TASTE.   I MOVED IN DECEMBER 2017 AND JUST PURCHASED A SECOND PC1000 FILTER SYSTEM FOR NEW HOME.  WHY CHANGE PERFECTION.  IF YOU ARE CONSIDERING A WHOLE HOUSE FILTER SYSTEM, MAKE THE JUMP.  YOU WILL BE HAPPY.
