Product review (1 stars): Less filtration and half the water flow.  Cheap isn't better. And there is a reason the Samsung is more expensive.
Like a lot of people I was put off the by the high price of the Samsung OEM replacement filter.  After some searching I decided to try the Water Sentinel WSS-2 three pack. It seemed to be a bargain.  The cylinder is a bit smaller than the OEM filter but fits fine without leaks.  After purging the air from the line I noticed the water flow was somewhat less than the original filter.  But decided to keep it on and see if it improved.  It did not.  Thinking I had a dud, I replaced it with #2 in the three pack.  Again the flow was about half what the OEM filter provided.  I installed #3 of the three pack and found even less water flow.  It is so slow that my wife is filling her water glass from the kitchen tap.  If you are patient you can fill a regular drinking glass in a couple of minutes.  That is ridiculous.

After additional research today, I also learned some important facts about the difference between the OEM Samsung branded filter and the WS WSS-2 filter.  When you read the specifications for each filter, you find that the WS WSS-2 filter is basically a carbon filter to remove chlorine taste and not much else.  The OEM Samsung filter is certified by the NSF to reduce contaminants such as  99.00pct of Asbestos 96.70pct of Benzene 97.40pct of Chlorine Taste & Odor 99.99pct of Cysts 99.30pct of Lead at pH 6.5 99.90pct of Lead at pH 8.5 98.00pct of Particulates (Class I) 99.10pct of Turbidity 94.60pct of Atrazine 99.00pct of Lindane.  The WS WSS-2 doesn't meet any certification requirements.

And that is why cheap isn't better.  I only hope that going back to the OEM filter increases the speed with which I can fill my water glass. I hope to do that today.
