Product review (5 stars): Joe M in Newport News, VA
Works fine on city water.  No after taste since day one; installed in early june of '18.  You need to soak your new filter before using it! maybe 15 minutes or so, then install new filter and leave the water in the filter when installing.  I don't know what exactly gets filtered out, but there is a distinct taste straight out of the tap.  The water out of the fridge and ice maker are similar to actual spring water you buy in the market or natural springs found most often in the mountains (Blue Ridge).  Worked great for the last 2 and a half months now and going strong!  No leaks either!
