Product review (2 stars): Design of the filter has been changed and it won't fit with my older Samsung model.
Have been buying this model of filters for many years.  All of a sudden, I can't get this one to fit in the filter housing.  It is fortunate someone has experienced this and found the resolution to shave off some extra plastic from the bottom of the long teeth both sides.  Viola, it fits again.  But it is very annoying Samsung made the design change.
