A vent assembly for a closed body fluid drainage system having a fluid retaining bag with a body engageable fluid draining tube extending therefrom. The venting assembly comprises, in spatial relationship, an outer, gas permeable, liquid-wetting bacteria filter, and an inner, gas permeable, liquid-repellent filter. In use, the vent assembly provides for the free exchange of gases flowing into and out of the fluid drainage system while effectively precluding entrance of bacteria and the like.
