An inflator (22) includes a structure (30, 32) that defines a first chamber (50) and a second chamber (80). The first chamber (50) contains a volume of fluid under pressure and the second chamber (80) is in fluid communication with an outlet passage (76). The inflator (22) also includes a closure member (90) openable to release the fluid to flow out of the first chamber (50). An initiator (100) is actuatable to open the closure member (90). The inflator (22) further includes a filter (130) disposed in the second chamber (80). The fluid is directed from the first chamber (50) into the second chamber (80) and through the filter (130) into the outlet passage (76) upon opening of the closure member (90).
