Product review (4 stars): For people concerned with counterfeits...
I purchased this in November 2016 for my Samsung side by side model RSG307AARS. I had no visible/taste issues or leaking as some people have posted. I am not sure if the one here is counterfeit or just a previous version but I just purchased the same filter directly from Samsung in July 2017 (for the same price and free shipping) and there were visible differences in packaging and labels.  The physical structure of the filter, including hole size appears identical. I don't still have the package from the one purchased on Amazon but the one I got from Samsung doesn't look like the picture posted here. The first two pictures are of the filter I purchased here (note the Samsung name is in black on the filter) and the top view.  The next 8 pictures are of the one I purchased from Samsung directly.  Note it says on both the printed box and with a metallic sticker that it is a genuine Samsung filter.  The filter itself has similar information but I noticed on both the box and filter, the word Samsung was in blue print (without the oval background) and the letter A was an upside down V which is similar to their brand identity.
