Product review (5 stars): Same results, half the cost!
No complaints. This filter looks exactly like the OEM Samsung filter. It installed perfectly and does not leak. The flow from the water spout if powerful and smooth and the water seems to be just as filtered at the OEM.

In the end, You just can't beat paying less than half the cost and getting the same results. According to the packaging this filter passes or exceeds all the same tests as the $40+ OEM filter. This is all from a standard consumer though, and I did not run any scientific tests. This has got to be better than NOT replacing the filter, which a lot of people do because of the cost. $40 is really not that bad on a per day basis, but seems like a lot when the day comes to change. And for the same results, $20 is a no-brainer.
