In smaller filters broken bags are usuaily located by checking each individual bag. This would be a very arduous task however on a larger filter. For filters with long cylindrical bags suspended from a tubesheet, a broken bag can sometimes be detected by a pile of dust on top of the tube sheet next to the broken bag.
