The annular seals have radially facing sealing surfaces which seal with the annular shoulder and with the diffuser. In another embodiment, the conical diffuser is mounted on a stanchion which is unitary with the base portion of the air filter housing. The frustoconical filter element is mounted on the base by receiving the stanchion and diffusion cone therethrough. The removable portion of the housing is then placed over the filter element and clamped to the base portion.
