Product review (5 stars): An Excellent Product!
I purchased the Samsung brand from Amazon and Loew's.  Even though my refrigerator was listed as one that the filter would fit, neither one did .  I had to return the filters.  I had used this filter from Waterfall Filter company previously and decided to  reordered 2. They arrived within a few days and fit perfectly.  This a very good product and I highly recommend it!
