Zusammenfassung:	An improved vented microporous membrane filter holder is described which is particularly useful as a final filter in intravenous therapy. The holder includes two parts, a filter support member and a cover member, both substantially tubular in shape. The support member includes a hollow tubular member having grooves formed in its outer surface. A wettable filter is sealed to this outer surface. A closed passage connects to all of the grooves and carries filtered liquid to an outlet port formed in the base which seals one end of the hollow tubular member. The other end of the tubular member is closed with a non-wetting filter. Gas passed by this filter, after passing through the center of the tubular support member, is vented out an opening also formed in the base. A cover is sealed to the base at one end and a inlet port is formed in the other end of the cover, which surrounds the tubular support member.
