Product review (1 stars): Does not filter much...
I was really excited about the price (half of the original one from Samsung), but then I tested the filtered water quality... Our tap water before the filter is 409 ppm, after this filter it's 390 ppm. In other words, you get the same result if you use coffee filter to filter your water...
Next time I get the original Samsung one and test it as well.

Update 4/27/2016: I had an opportunity to test the original Samsung water - the reading with the original filter is 365 ppm, which is 25 ppm better than this replacement (non-OEM) filter.
