1. A modular lid of a sterilization container comprising:
a modular body including an inlet and a plurality of movable body segments, wherein the modular body is configured to selectively expand and collapse the plurality of movable body segments relative to one another to thereby selectively adjust a longitudinal length of the modular lid;
a first filter structure disposed within the modular body and including a first plurality of ridges and a first plurality of troughs formed between the first plurality of ridges; and
a second filter structure disposed within the modular body and including a second plurality of ridges and a second plurality of troughs formed between the second plurality of ridges;
wherein the first filter structure is to the second filter structure such that the first plurality of ridges is coupled to the second plurality of troughs and the first plurality of troughs is coupled to the second plurality of ridges thereby forming a series of rectangular channels within the modular body to define a rectangular tortuous filter path that inhibits ingress and egress from the sterilization container; and
wherein the first filter structure and the second filter structure are configured to expand and collapse in response to expansion and collapse of the plurality of movable body segments of the modular body.
