Product review (4 stars): How do you rate water filters?
I only give is a 4 star rating because I don't know how well it works.  This is the filter I need for my Samsung refrigerator and I have been using it for 1 1/2 years.  I can't say it doesn't work because my water taste and smells great coming from the refrigerator.  I wish there was some way of positively rating this product, but there simply isn't.
