Product review (1 stars): DO NOT BUY
DO NOT PURCHASE THESE FILTERS.  I have tried six of them and every one of them caused a hammering sound when water was dispensed and/or when water filled for ice.  I had a certified technician out to replace the water valve twice.  The third time, the hammering sound happened when the valve was disconnected.  This clearly told me that is was a problem with the filter.  The filter looks identical to original equipment and it fit fine with no leaks.  I am convinced that it is an internal problem.  I have since replaced  with an OE Samsung filter and the problem was immediately resolved, 4 weeks now and no hammering sound.  Honestly since I have replaced with an OE filter, the water and ice taste much better as well.
