Product review (1 stars): Filter did not work
After following the directions to install the filter, it made a horrible and loud noise when the install door was closed.  The noise continued every time we tried to run water.  I ran the system for more than 5 minutes and the noise remained.  I put the old filter back in and there was no noise, so clearly it was this filter.  I'm not sure if this particular one was defective or what but I will not be using it.
