A compact filtering device for use in pyrotechnic gas generators comprising of series of small conduits which generally transport the exhaust products from the combustor exit ports to the generator exit ports. Particulate traps (12): which are created by locating the conduit exit ports (11) at some point prior to the conduit end. Particulate traps (12) consisting of entire conduits are created by placing one end (10) of the conduits at a point where the gas stream is forced to make a 90 DEG change in direction and by orienting the longitudinal axis in the direction of the original flow path. Because the traps are then located outside the flow path the particulate, once deposited, will remain in the trap. The device is capable of capturing all of the particulate generated without any change in resistance to gas flow.
