Product review (5 stars): Worked for  2015 Model RS22HDHPNSR
I have a 2015 Samsung refrigerator 22cu.  Model RS22HDHPNSR
This filter fit perfectly.  Didn't seem much larger if at all to the original DA29 00003G filter which came with my fridge so I didn't have to adjust my shelf.  Watched for 48 hours for leaks- none.  Ran about 8 cups through to clear the air from the line.
