Product review (5 stars): Fit my Samsung Refrigerator Just Fine
Actually, this filter is slightly taller than the original Samsung filter. I was able to remove the Samsung filter without removing top tray panel.  But it wasn't possible with this filter.  I had to remove the top panel before I could insert this filter - not a big deal. I ran about 5 gallons of water afterwards to flush out the filter and the water lines. The water and ice taste good.  The local water has a very high mineral content and I don't like the taste. There was some o-ring lubricant included, but I didn't use it. There are no leaks, so it isn't needed. The instructions stated it is optional in case of a drip. So I'm pleased that I have a reasonably priced fresh water filter again.
