Certain embodiments of the invention may include filters, systems, and methods for reducing can velocity. According to an example embodiment, a filter is provided for filtering particles from air or fluid. The filter includes a first end and a second end, wherein the first end includes an aperture; one or more sections of pleated filter media including a plurality of pleats formed in a substantially conical shape about an axis and around an inner void region in communication with the aperture, wherein a diameter associated with the first end aperture is greater than a diameter associated with the second end; and one or more radial support regions in circumferential contact with at least one of an outer surface of the filter media, wherein spacing of at least some of the plurality of pleats are maintained at least in part by the one or more radial support regions. |
