1. A method for filtering a gas comprising:
passing a gas through a compartment of a filter assembly, the filter assembly comprising:
an inlet opening;
a plurality of outlet openings fluidically coupled to the inlet opening;
a casing comprising polymeric film and bounding the compartment, the compartment communicating with the inlet opening and the plurality of outlet openings; and
a plurality of filters at least partially disposed within the compartment, each of the plurality of filters associated with a corresponding outlet opening of the plurality of outlet openings;
forming a first seal across a first section of the casing at a location between the inlet opening and at least one of the plurality of filters to form a first sub-compartment within the casing; and
severing the casing at a first location.
