Abstract
A micropore filter of discrete flow-through pores of highly controlled pore configuration and dimensions is formed by bonding platelets into a laminate, each platelet having been etched, preferably by a combination of electropolishing and photoetching techniques, to form depth-etched passages and through-etched passages, respectively. The filter is housed in a module which contains wiper blades for periodically removing deposited debris from the filter surface.
