A vial access device (300, 400) comprising (i) a fluid filter assembly comprising: a connector member for receiving a medicament delivery device, the connector member providing fluid communication with medicament delivery device, and a housing containing a fluid filter; (ii) an upper housing receiving the fluid filter assembly at a top surface, the upper housing comprising a spike having a longitudinal axis and a proximal end and a distal end, the proximal end projecting from a bottom surface of the upper housing, the spike having at least one lumen (312, 328) arranged parallel to the longitudinal axis, the at least one lumen connecting the proximal end of the spike with the distal end, the at least one lumen being in fluid communication with the fluid filter; and an opening receiving a vent filter assembly (3050, 4050) with a vent filter (304, 405) having a vent filter surface; characterised in the fluid filter having a front surface aligned non-parallel with the longitudinal axis and substantially perpendicular to the direction of fluid flow in the at least one lumen, and the vent filter surface positioned essentially perpendicular to the liquid filter surface; and (iv) a shroud projecting therefrom and at least partially surrounding a portion of the spike; the shroud configured to receive a vial or container.
