A stackable lid (100) and corresponding fluid collection canister (500,600) are provided. The stackable lid (100) has a lid member (101) that defines a first partial lid interior portion (201) and a second partial lid interior portion (202). One or more ports (107,108,109) are disposed on the first partial lid interior portion (201), with a filter engagement extension (301) extending beneath one of the ports. A stacking recess (211) is disposed on the second partial lid interior portion (202), and can be out of phase relative to the filter engagement extension (301). When lids are stacked correspondingly out of phase, a filter (902) coupled to the filter engagement extension (301) nests within the stacking recess (211), thereby reducing overall stack height by sixty percent or more.
