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: Certain exemplary aspects of the present disclosure are directed towards an apparatus including a base deck forming a sealed cavity. A filter coupled to a surface of the base deck within the cavity filters particulate from a flow of gas in the cavity. The recirculation filter including a protrusion extending over a surface of a storage medium within the cavity that diverts gas from a surface of the storage medium toward the filter. A bypass channel, defined by a portion of the cavity and a portion of the filter, in conjunction with the protrusion forms a pressure differential that draws a first portion of the diverted gas through the filter by bypassing the filter with a second portion of the diverted gas.

Abstract: Certain exemplary aspects of the present disclosure are directed towards dual cavity apparatus and related methods involving hermetically sealing the cavities by evacuating and atmosphere therein, filling the cavity with a gas, and sealing the gas in the cavities. This evacuation and fill approach is carried out through openings that provide access to the cavities. During evacuation of at least one of the cavities through one of the openings, one or more spacers prevent the cavity from collapsing in response to the vacuum force.
