Home tap water has bad taste. On second filter and water still taste better. Two points of concern though. The first is drops of water that fall onto removable tray dry leaving behind white minerals. I thought the filter would remove these particles. Second issue is my wife finds a slight soreness to her throat, like an acid burn, when drinking water from door or soda as with the ice from the dispenser. We have a Pur Water Filter Pitcher and she doesn’t feel this soreness when drinking from the pitcher nor when she drinks her soda straight from the can. We’re using the PureSource Ultra II. I see your filters are made in Singapore so I wonder if this could be a quality control issue as my wife didn’t have this problem with our previous filter which came with the refrigerator when we bought it new.
