A depth filter design is disclosed which has little if any open void area
upstream of the media. Preferably, it also has little if any open void
area downstream of the media as well. A preferred embodiment uses layers
of stacked, fibrous media with several of the layers being separated from
the others by spacers which serve to compress the media and to prevent
the bypass of fluid around the media adjacent the inner wall of the
housing. Several designs for attaching the end caps which allow for the
compression of the media are also disclosed.
