Product review (5 stars): Good Value
These replacement filters are less than half the cost of the original Samsung product and they seem to work just as well. The only difference I can tell is you can hear the charcoal rattling around in these filters and the original Samsung filters do not make any noise when you shake them. I think the charcoal packing in the original filters is tighter, but these seem to work just fine (i.e., the water is clear and odor free). I do change the filter every six months as recommended and I have never had a problem with these filters.
