Abstract: A non-fouling, bypass filter is disclosed. The filter is formed of a tapered structure having particulate material filtering properties. The tapered structure has an open base and a closed top, with its exterior surface being exposed to a gas/fluid stream to be filtered. A gas/fluid stream generating device generates a gas/fluid stream that is drawn into the tapered structure's interior and that is filtered due to the particulate material filtering properties of the tapered structure. The external profile of the conically shaped structure is adapted to cause a plurality of gas/fluid streams from the ambient gas/fluid to flow against the exterior surface of the tapered structure to prevent the building up of particulate material on the exterior surface.
