A grill assembly, arranged at the air outflow port (112), has multiple slots (320) in the outer periphery of the grill main body (310) and spaced at constant interval to form a passage towards the air outflow port. The grill assembly prevents reverse flow of contaminants collected in a dust receptacle (200) via air outflow port. The detachable dust receptacle is connected to the cyclone main body (100) for receiving contaminants separated from air. A contaminant removing unit moves along the outer side of the grill in the up and down motion to remove contaminants. Independent claims are also included for the following: (a) Dust receptacle; and (b) Grill and sweeper assembly for one-way filtering apparatus. |
