  • Filtration, filter characterization, and methods and apparatuses therefor
    Patent number: 10549228
    Abstract: Aspects of the disclosure are directed to apparatuses and methods involving filters and detection of operation thereof. 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.
