Product review (4 stars): LIKE I SAID IN MY PREVIUOS REVUE
LIKE I SAID IN MY PREVIUOS REVUE, I DON'T KNOW IF THE FILTER IS REMOVING WHAT IT SAYS IT'S SUPPOSE TO REMOVE. I CAN'T FIND A PLACE TO TEST A USED CARTRIDGE. IS IT REALLY FILTERING OUT SOMETHING DURING USAGE. $20-$30 EACH OR $4-$5 A MONTH FOR MAYBE PEACE OF MIND ???????????
