Fart fans will move air but won't push it into a high static pressure ie. through ducts or filters very well. They will move air out of your room and into an attic or other (well vented) airspace pretty well if no ducting is needed, though.

Common fart fans usually have plain bronze bearings and are not intended for continuous running. For about 2x the price, the local hdwe will also have fart fans with ball bearing motors that will run continuously without grief.
