The invention belongs to the technical field of air conditioner filtering devices of aircraft environment control systems, and particularly discloses a filtering device filtering efficiency test system and test method. Comprises: a dust generating device (15); the dust generating device (15) comprises a dust containing cover (4), a dust containing cover upper end cover (3), a pressing nut (2), a ventilation pipe (5), a ventilation base (9), a locking nut (6), a filter screen (8), a ventilation inlet (1) and a ventilation outlet (7). The top of the ventilation base (9) is connected with the dust containing cover (4) and fixed through the locking nut (6), the filter screen (8) is arranged in an inner cavity of the ventilation base (9), and the ventilation inlet (1) and the ventilation outlet (7) are connected to the two ends of the ventilation base (9) respectively. The dust containing cover upper end cover (3) is fixed to an opening in the upper end of the dust containing cover (4) in a sealed mode. One end of the ventilation pipe (5) is connected with an external interface fixed on the dust containing cover upper end cover (3), and the other end of the ventilation pipe (5) extends into an inner cavity of the ventilation base (9); a dust inlet is formed in the dust containing cover upper end cover (3), and the pressing nut (2) is matched with the dust inlet in a sealed mode. The test device effectively simulates the working state and the working environment in aircraft environment control bleed air.
