An air cleaner which includes a support (23) having a first concave conical surface (26) and compression means (50) extending along the axis of said surface away from the apex of said surface; an hollow inner filter (37) including a first end cap (41) with a rim (43) defining a first convex conical

An air cleaner which includes a support (23) having a first concave conical surface (26) and compression means (50) extending along the axis of said surface away from the apex of said surface; an hollow inner filter (37) including a first end cap (41) with a rim (43) defining a first convex conical surface having the same apex angle as said first concave surface, and a second end cap (42) for axial engagement by said compression means; and a hollow, outer filter (32) including an end cap (57) with a resilient lip (61) extending inwardly to be sealingly received between said conical surfaces when said compression means engages said second end cap. The second end cap of the inner filter may have a second convex conical surface (47), and the outer filter may have a second end cap with a resilient lip extending to be sealingly engaged by the second convex conical surface.

An air cleaner comprising, in combination: a support having a first concave conical surface, compression means extending along the longitudinal axis of said surface away from the apex of said surface and outlet means for releasing filtered air from said cleaner; a hollow inner filter surrounding the longitudinal axis of said support, said inner filter including a first end cap, with a rim defining a first convex conical surface having the same apex angle as said first concave surface and positioned adjacent said first concave surface, and a second end cap which is in axial engagement by said compression means; and a hollow outer filter positioned substantially around said inner filter, said outer filter including a first end cap with a resilient lip extending inwardly so as to be sealingly received between said conical surfaces due to said compression means engaging said second end cap and air inlet means for introducing unfiltered air flow into said cleaner.
