1. A filter cartridge for use in separating a hydrophobic liquid aerosol phase from a gas stream and for use in filtering the gas stream; the filter cartridge comprising:
(a) a media pack comprising filtration media surrounding an open interior and including first and second, opposite, ends; (b) a first end piece adjacent the first end of the media pack; the first end piece having a first, outer, end surface on an opposite side of the first end piece from the media pack;
(i) the first end piece including a perimeter housing seal arrangement thereon; the perimeter housing seal arrangement comprising a seal member configured to form a releasable seal with a housing, when the filter cartridge is installed in a housing, for use;(ii) the first end piece including a central flow aperture arrangement projecting therethrough in communication with the open interior of the media pack;(iii) the first end piece including a peripheral rim projection extending in a direction away from the media pack; and,(iv) the first end piece having a recessed surface portion extending between the peripheral rim projection and the central flow aperture arrangement.
