Product review (5 stars): Fits Samsung RF24FSEDBSR
I didn't purchase my replacement through Amazon but thought this review might help others - my Samsung frig size wasn't referred to in the description so I was concerned that if I did buy it online that I'd have to ship it back if it wasn't the correct replacement. So just an FYI that this did fit the Samsung RF24FSEDBSR. My filter light went on about 6 months from the date my frig was installed and although I do use the water and ice, I live alone so I suspect that I probably could have delayed replacing it.  I didn't want to see the filter light on and I didn't want to reset it without replacing so I just bought the new filter.  It was a little difficult getting the old filter out - they don't leave a big enough grab space and the material is slick. I took one of those rubber pads that are made for opening up jars (provided a better grip) and then placed a pliers over it and pulled (after I unlocked it.)  That did the trick.
