If you use a paper filter or something similar, it most probably will blow up, as it will provide too much resistance to the flow of water, IMO.

Best to use filtering wool like material used in aquarium filters, it has relatively large open cells but the fibers provide great fine filtering without restricting water flow too much.

I personally use for my aquariums the type that is blue on one side and white the other side, it comes in large pieces you can cut to fit any opening.
