Abstract
Embodiments of the invention generally provide a filter module having a mechanically positionable test probe disposed therein and a method for testing a filter. In one embodiment, a filter module includes a housing adapted to receive a filter element. A sample probe suitable for leak testing the filter element is disposed in the interior volume of the housing. The sample probe may be moved to scan the filter by an actuator. In another embodiment, a method for testing a filter includes challenging a room side of a filter element disposed in a housing with a test aerosol, moving a probe disposed within the housing to obtain samples for testing and determining if the samples exceed a predefined leak criteria.
