A sealing and venting arrangement for positioning between a fluid dispenser and a replaceable container of said fluid, an annular element having one portion thereof resiliently engaging said container and having a second portion resiliently engaging said dispenser, a venting aperture extending through said sealing element, said element having a base portion from which a first annular resilient and tapered flange element extends upwardly and from which a second generally L-shaped flange element extends radially outwardly with said first element being sufficiently resilient to conform with surface irregularities on said container and with said second element being sufficiently resilient to conform to surface irregularities in said dispenser, said venting aperture extending through a portion of said base portion and also through a portion of said tapered flange element, chamber means formed on said sealing element, and a replaceable filter element releasably secured in said chamber, said chamber means extending only partially around the periphery of said sealing element without disturbing appreciably the resiliency of said first and second flange elements.
