Product review (2 stars): 230ppm "filtered" water
I don't have noise issues or a problem with the fit on the fridge.  I believe the manufacturer reduced the carbon filter density to solve this problem.  My tap water is 280ppm on the water quality tester and the filtered water was 230ppm.  Filtered water should have no more than 100ppm Max.  The filters appear to work without noise and problems because they are not filtering the water.  This may actually be a scam.
