Claim:
A method for filtering a gas using a low-profile filter comprising; mounting a filter to a substrate block, wherein the filter comprises; a filter housing; a filter cavity defined to extend in a generally horizontal direction when the filter is in use; a first flow passage that connects an inlet at a first surface of the filter housing to a first section of the filter cavity; a second flow passage defined to connect a second section of the filter cavity to an outlet at a second surface of the filter housing on the obverse side of the filter housing from the first surface; a pass-through flow passage having a first pass-through passage opening and a second pass-through passage opening, the pass-through passage running from the first surface of the filter housing to the second surface of the filter housing and bypassing the filter cavity; a filter assembly comprising a filter disposed in the filter cavity and sealed to the surface of the filter cavity separating the filter cavity into adjacent sections including the first section of the filter cavity and a second section of the filter cavity; wherein the inlet, outlet, first pass-through passage opening and a second pass-through passage opening are configured and spaced to interface with corresponding ports on a substrate block and a single gas device; directing the gas from the inlet in the filter housing to the first section of the filter cavity; flowing the gas through the filter to the second section of the filter cavity to filter the gas; directing the gas from the second section of the filter cavity to the outlet in the filter housing.
