When filtering by file extension, it's best to use the Filename Filter on the Header Filter tab in the settings. It not only filters on the subject but on the name in the article body as well so it catches articles that have inaccurate information in the subject. If it doesn't match the subject, it will download the file and then delete it if it matches the filter.
On the Header Filter tab there is also an option to filter files smaller than the given size. That might be handy.
