Product review (5 stars): Samsung DA29-00020B Refrigerator Water Filter
I have purchased these Samsung water Filters several times before and have always been satisfied with their fit, performance, and full six months of service.  It's possible that some of the compatible filters work as well, but why take chances, especially when the price differential is so small.  That's why I always buy the original Samsung OEM filters.  Stick with the ones that work.
