Abstract
A filter housing assembly having a leak testable aerosol injection port is a conduit coupled to an aerosol injection selectively traps aerosol port of the filter housing assembly after disconnecting an aerosol generator used to challenge a filter installed in the housing assembly. The trapped aerosol provides a high concentration challenge that facilitates leak testing of the aerosol injection port after the aerosol generator has been removed.
