Product review (1 stars): which was annoying.
These filters have a double o-ring gasket around the top lip and did not work correctly in our fridge.  We've ordered several in the past that had a single o-ring gasket that worked well.

I called Samsung and they said that they actually have multiple products with the same DA29-00020B part number - which is very confusing.  They also said they can only help me if i order the product from their samsungparts.com website, which was annoying.
