Abstract
According to some embodiments, a vent filter for a waste tank system is provided having a housing which eliminates or reduces the amount of bypass of odorous air moving through the vent system and precludes the odorous air from escaping without passing through filtering material. The housing includes a region wherein the cross-sectional area is reduced, inhibiting bypass of odorous gas past the filtering material.
