초록

Constructions and methods are described for collecting particulate material from gas streams. In one specifically described arrangement, a region of depth media is oriented upstream of a second region of depth media. A surface loading media is positioned downstream from the second region of depth media. In an alternate embodiment, a further region of filter media is positioned downstream from the surface loading media.
