An in-line set filter for parenteral solution sets and the like which comprises a tubular housing having first and second ends. A bundle of filter tubes is positioned within the housing, the filter tubes preferably being folded so that all ends of the filter tubes occupy a single zone in communication with the first housing end. The zone is filled with potting compound with the filter tube ends communicating through the potting compound and open to the exterior. A flow access port is laterally positioned in a side wall between the second end and the potting compound but closer to the potting compound. The second end defines an open aperture occluded by a porous hydrophobic filter to permit venting while preventing loss of aqueous liquid.

A filter which comprises a tubular housing having first and second ends, said first end being adapted for connection to downstream tubing of a medical fluid administration set, a bundle of filter tubes positioned within said housing, said filter tubes being folded so that all ends of said filter tubes occupy a single zone in open communication with the first housing end, said zone being filled with potting compound surrounding said tubes and adhering to an inner wall of the housing with the filter tube ends communicating through said potting compound and open to the exterior of said housing at the first housing end, a flow access port adapted for connection to upstream tubing of a medical fluid administration set, said flow access port including a tubular section which is in parallel juxtaposition to said housing, said flow access port being laterally positioned in a side wall of said housing between said potting compound and said second end, at a position closer to said potting compound than to said second end, said second end defining an open aperture occluded by porous, hydrophobic filter means to permit passage of gas while preventing passage of aqueous liquids, said tubular housing being adapted for retention in the upright position by said tubular section when fluid flows therethrough so that gas bubbles can easily pass through said porous hydrophobic filter means.
