Product review (2 stars): Not Good for Hard Water Areas
I had replaced the filter in my Samsung refrigerator several times before with a Samsung filter but then decided to give this filter a try since it was several dollars cheaper.  The filter fit fine but unfortunately it was NOT filtering as well as the Samsung filters had done in the past.  I like my water at room temperature so I would fill a glass and let it sit on the counter a short while before drinking.  Using this filter the water had a horrible after taste.  If you drank the water while ice cold there wouldn't be any after taste.  I believe this is due to the HARD water in my area.  I switched back to a Samsung filter and the after taste was gone.  I followed all the flushing instructions prior to drinking and even gave it a week before buying a Samsung filter.

I gave it 2 stars because it did fit fine and I'm sure it filters some of the impurities out but not enough to my liking.
