Product review (5 stars): Don't buy Samsung filters!
Originally bought a Samsung filter ($49.99 at Home Depot) but discovered Samsung has "redesigned" their filters and even though the part number is the same, it does not fit!  There was a Waterdrop filter in the fridge, so I ordered a package of 4 for less than $40!  Easy installation and Home Depot took the Samsung filter back.  Will buy these again for sure!
