Product review (5 stars): Fits as replacement for DA29-00019A in my Samsung RF28HFEDBWW/AA)
This fits perfectly in my fridge (Model # RF28HFEDBWW/AA). The original part for my fridge was supposed to be the DA29-00019A filter and this filter was mentioned as the replacement on Samsung's website. I bought this with some trepidation because there was a negative review saying that this item (DA29-00020B) did not work as a replacement for the 19A filter, and a question I asked on Amazon had mixed responses. It turned out that it does work, and we have cool, great tasting filtered water again!

Also the item I got was rated "Particulate Class I" whereas my fridge originally came with a "Particulate Class III" filter. So overall it looks like I got a better filter than I had for a much better price than buying at a store.
