Product review (5 stars): It works, good price, what else is there?
So not sure about the previous reviews stating that these cost more in a 3 pack versus individually, when I did my shopping the 3 pack was less expensive (not by much, but still).  This filter went into our Samsung fridge (these are OEM Samsung filters by the way, not 3rd party) RF4287HABP with no issues, just like the filter that came with the fridge.  Water tastes fine, no issues there - I don't have a way to measure the crap in the water, so I can only assume the filter is doing its job.
