A fluid collection system includes a disposable collection container configured to receive a disposable collection container. The fluid collection container may include a flexible liner configured to collapse during evacuation of the fluid from the liner. The system may include a receiving housing sized to receive the disposable collection container, the receiving housing including a cavity and a piston assembly positioned within the cavity, the piston including a piston check valve. The system includes a suction source connectable to the disposable collection container and a filter positioned between the suction source and the cavity. A first connecting line extends between a suction source opening, configured to communicate the suction source to the disposable collection container, and the filter. A first check valve connects to the first connecting line between the suction source opening and the filter.
