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.

12. A system for filtering a gas comprising:
-
a container having a compartment configured to hold a liquid, the container comprising a flexible bag; a first filter assembly comprising a first gas filter, the first filter assembly being coupled with the container so that a gas can pass from the compartment of the container to the first gas filter; and a first vacuum pump coupled with the first filter assembly so that when the first vacuum pump is activated a partial vacuum is produced that assists in drawing the gas from the container through the first gas filter. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 24, 25)

21. A system for filtering a gas comprising:
-
a filter assembly comprising; a casing comprised of a flexible sheet of a polymeric film and bounding a compartment; an intake port coupled with case and communicating with the compartment; and a first filter comprising a porous filter body through which gas can pass and an exhaust port coupled with the filter body, the first filter being coupled with the casing so that the filter body is at least partially disposed within compartment of the casing and so that gas passing through the compartment of the casing from the intake port to the exhaust port must pass through the filter body; and a vacuum pump coupled with the exhaust port of the first filter so that when the vacuum pump is activated a partial vacuum is applied to the exhaust port. - View Dependent Claims (22, 23)
