Product review (5 stars): I'm now the favorite child.
After almost a month of seeing "REPLACE FILTER" every time I looked at the fridge, my mom bequeathed the responsibility to me, telling me to go to Sears. I went there and asked someone for help. Spent about an hour or so with the Sears worker trying to help me figure out the fridge fix, but I ended up leaving the store empty handed.

That night I googled "samsung fridge filter". Lo and behold, this was one of the first hits that popped up. Yay, it fits in our fridge!

Suitable for Model RF32MQDB (what we have).
