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.

Abstract: An environmental control assembly includes a housing including a base layer, a diffusor layer, and an interior space at least partially formed by the base layer and the diffusor layer. The environmental control assembly further includes a desiccant positioned within the interior space and an inlet filter that is formed from a cutout in the base layer that is covered by the diffusor layer.
