Zusammenfassung:	A modular filter assembly is described comprising a filter stack having a plurality of filter sheets and a plurality of filter support plates each having a perimeter and an internal filter flow passageway portion. The filter sheets are sandwiched between surrounding filter support plates forming the stack and the filter flow passageway portions of the plates and filter sheets are aligned to form a filter flow passageway extending from the top to the bottom of the stack. The filter stack has engaging means capable of keeping the filter support plates together while minimized top to bottom dimension because it is not necessary to use external clamps for keeping the support plates together. Also described are support plates for modular filters and a method for forming a modular filter assembly.
