A filter, comprising a hollow body of porous material, having the shape of a truncated circular cone having an axis extending between a smaller end and a larger end; a resilient connection annulus connected to said larger end of said body and including a flat axially outward surface and a radially inward concave surface including a medial circumferential groove; and a centrally apertured resilient mounting member connected to and substantially occluding the small end of said body, said mounting member having a central lip extending axially around the central aperture. An air cleaner comprising: (a) a generally cylindrical housing having an axis extending between first and second ends, an air inlet, and a fixed closure for said first end including an axial aperture; (b) an outlet tube mounted in the axial aperture and projecting within the housing, said outlet tube having a circumferential bead at its inner end; (c) a filter comprising a hollow body of porous material, a resilient connecting annulus connected to a first end of said body, and a centrally apertured resilient mounting member occluding a second end of said body, said annulus having a sealing surface which bears axially against said fixed closure, and having an inward groove engaging said bead, to prevent passage of air from said housing to said outlet tube passed the first end of said filter; (d) means mounting said filter within said housing comprising a mounting yoke having legs secured to the inside of said outlet tube, said yoke extending axially of said housing through said filter and including a shaft passing outwardly through the aperture of said mounting member supporting said filter coaxially in said housing; (e) and clamping means securing said mounting member frictionally to said shaft.
