Product review (1 stars): Water tasted nasty
Biggest waste of money EVER!!  If your water tastes find out of the tap then forget the filter in the fridge.  Just keep resetting the light, it's on a timer not if the filter is dirty.  My water tests at about 40PPM dissolved solids in the water.  I changed the filter and suddenly my water tasted nasty, I checked it and the reading was 212PPM.  I was like WTF it suppose to take stuff out not put gunk in.  I put the old filter back in, the one that is used up.  In three glasses it was back to 50PPM and tasting fine again.  If you want to find out what clean pure water tastes like; try Zero Water.  I used it at my last house, I don't need it at this new house.  That is where I got the tester and it has always been true for me.
