I have filtered out polygons and in several cases when using snapper turned two polygon into a new one which lays on top of the old ones. Attached is a workspace and data and an example is an polygon with "externid" "0331>JULMYRA>1:33>1>>>>1" which there are two of but one is a combination of two polygon (mentioned before+"0331>JULMYRA>1:63>1" and hence covers a larger area, (33k sqm vs 15k sqm). I would like to be able to filter out the duplicates and save the smaller polygons.
Question
Issues with duplicate polygons, need filter out the smallest with identical attributes.

The Duplicates output port of the DuplicateFilter contains all duplicate features encountered after the first one. So if you sort on externid and _area before the DuplicateFilter it should output the smallest ones through the Unique port.
