Damn Michael that was real encouraging (you may have just scored a few cyl walls oh well dont worry about it). The last time I sucked in something from a broken filter I ended up with a tow truck and looking for another engine the same day so I don't think you have anything to worry about now. You likly burned away any small objects or have them emulsiated in your oil (change it to be sure). Anything big enough to screw your engine up probably would have. No need to worry about it cause what the hell can you do now. Like two days ago I put the wrong spark plug wire to the wrong cyl (nearly god damn impossible on our car), cranked the bad boy 3X before it came to me "maybe its not starting and cranking fucked up for a reason". If you dont know its physically impossible to make cyl 1-4 and 2-3 go in the same direction without silly putty for a crank which is what firing the engine was attempting to do. I put it right, started it and ran it around the block a few times. Then I said "fuck it" , not like I got any rememdy if it fucks up anyway.
