Abstract
A method for filtering a gas includes sparging a gas through a liquid within a compartment of a container. In one embodiment the container can comprise a flexible bag. The sparged gas is passed from the container through a gas filter of a filter assembly. A partial vacuum is applied to the gas filter so that the partial vacuum assists in drawing the gas through the gas filter.
