Product review (5 stars): It does work!
This is the second water filter, purchased at Amazon, I've replaced in my Samsung fridge.  I stuck with the name brand to be safe and the only thing I know for certain is this: When I didn't change the filter as required, the water line eventually clogged and no ice was made.  I'd have to clear the line to get it going again. When the filter is changed about every 6 to 8 months, no problems of that sort.  The water in our area does not taste like minerals - it's more like bottled water - so the taste is the same either way.  And Amazon, as usual, has a very good price for these filters.
