Product review (5 stars): Easy to install and works great
I purchased my Samsung refrigerator about six months ago and was surprised when the replacement light went on for the filter already since I live alone, how much water could I drink?  When I read into it, it seems that six months is the shelf life for these filters and they recommend, so I set out to order my new filter.  After seeing the Samsung price on their website, I was dismayed at how expensive it was for something that had to be replaced every six months, so I headed over to Amazon and found this substitute for under $20.  I ordered it and it came promptly and was a breeze to install.  The water comes out as crisp and clear as the original Samsung filter, so no complaints from me.  I didn't actually test the water before or after for contaminants, so I can't speak to the effectiveness of that, but for good tasting drinking water, it works great.
