    摘要： Enhanced performance fibrous media (60) is provided by orienting filter media fibers (62) dominantly parallel to the fluid flow direction (46). Filter media construction is provided by a sheet (80) having an internal pleated subsheet (88) with pleats (92, 94) engaging and packed against each other sufficiently tightly and bonded (104) such that fluid flows along the flow direction through the pleats in parallel therewith, rather than between the pleats and then transversely therethrough. An extended life two-stage fluid filter assembly includes first and second filter elements (80 and 112), wherein the pleats (114, 116) of a main downstream filter element (112) are spaced from each other along a spacing direction (122) transverse to the flow direction (46) and defining a transverse gap (124) therebetween through which fluid flows, and wherein the pleats (92, 94) of an upstream prefilter element (80) are packed against each other without such transverse gap and blocking fluid flow therebetween.

    摘要： An air filter housing (12) includes twist and lock structure (42) having a first position (FIGS. 5, 7, 10) permitting axial movement (66) of a cover (34) and base (36) relative to each other, and being rotatable in a first rotational direction (44) from the first position to a second position (FIGS. 4, 6, 9, 12), and in the second position preventing axial movement of the base and cover relative to each other, and being rotatable in a second opposite rotational direction (64) from the second position to the first position. Anti-rotation lock structure (70, 110, 140) provides a rotational retention force holding the twist and lock structure in the second position. The anti-rotation lock structure includes an arm (74, 112, 142) flexibly bendable about a bend line extending parallel to the axis (14) of the housing.
