As may be consistent with one or more embodiments, an apparatus includes a fixture having mechanical components that hold a filter. Gas flow componentry operates with the fixture to eject particles from the filter by subjecting the filter to gas flow. A flow metering circuit meters the gas flow, and a particulate counter detects the ejected particles.
