Abstract: There is disclosed an air filtering mask having a cyclone filter member attached to a mask body, the cyclone filter member including a hollow slotted cylinder section attached to the base end of a hollow frusto-conical section and a hollow vortex finder having a substantially cylindrical body and two ends, one end being radially connected and sealed to the interior wall of the hollow cylinder section and the other end being located within the base end of the hollow frusto-conical section, the cylindrical body of the vortex finder extending coaxially through and being uniformly spaced from the interior wall of the hollow cylinder section, the hollow cylinder section having a multiplicity of slots through the walls thereof, the multiplicity of slots being aligned to penetrate into the region between the hollow vortex finder and the hollow slotted cylinder section tangential to the interior wall of the hollow cylinder section, the frusto-conical section having an opening in the apex end thereof.

Abstract: A cyclone separator having a central fluid conduit. An interceptor ring is externally attached to the end of the fluid conduit and has a surface which intercepts fluid flowing longitudinally along the outer surface of the fluid conduit and directs the fluid outwardly toward the interior wall of the container. Circumferential and longitudinal slots are located in the container in proximity to the interceptor ring to enhance the outward direction flow of fluid from the ring. A diffuser collar having a central opening therein is connected to the interceptor ring in a manner leaving an annular space or circumferential slots between the ring and the collar through which space unwanted materials.In an alternate version the diffuser collar is larger in diameter than the fluid conduit and the conduit extends into the diffuser collar forming a space therebetween by which an outer layer of fluid is skimmed from the spiraling column of fluid entering the fluid conduit to further cleanse the fluid of unwanted substances.
