Patent ID: 8033304

Claim:
A method for filling a filter assembly with a contaminant control media, the method comprising: a) providing a housing, the housing comprising: (i) an internal cavity defined by a first surface, a second surface and one or more sidewalls connecting the first and second surfaces, (ii) at least one fill port in communication with the internal cavity, (iii) at least one breather port in communication with the internal cavity, wherein the contaminant control media is of sufficient size, shape, or composition that it is unable to pass through the breather port, and (iv) a filter media at least partially covering at least one surface of the housing; b) coupling the housing to a loading station at an attachment location, wherein the attachment location forms a seal sufficient to draw a partial vacuum across the filter media, c) sealing the breather port such that a partial vacuum can be generated within the internal cavity, d) providing contaminant control media; e) creating a negative pressure within the internal cavity by drawing a partial vacuum on at least a portion of at least one surface of the housing at least partially covered by filter media to flow air through the fill port; f) drawing the contaminant control media through the fill port into the internal cavity, g) uncoupling the housing from the loading station and loading unit, and h) sealing the fill port after drawing the adsorbent material into the internal cavity.
