It is easy to write search terms to find any combination of formats.
For instance you might use the search string "not format:ePub" if your preferred format is ePub to know here conversion is outstanding. Using "format:ePub" could be used to find all formats where you have ePub versions so that other formats an be removed.
However as stated elsewhere I personally prefer to keep the original formats around so that I can reconvert if I later find I want to tweak the conversion parameters.
