What's more of a concern IMO, is the fact that once the media has torn there is no guarantee that it all stays in one piece. There could easily be small pieces of media coming off the torn edges. You would never know (unless it causes some kind of engine damage), and couldn't really tell by looking unless there was an obvious amount of media missing.
