Product review (2 stars): Needs to be modified for me
The filter that came with my refrigerator had perforations on both sides to remove the side panels.  These filters only had one side perforated and it was stated that for my model, only one side needed to be opened.  But the only way I could get the 'change filter' light to go out was to cut out the other non-perforated side with scissors.  Then it worked fine.  If you don't mind doing some mod work, then I guess you have no choice anyway.
