Zusammenfassung:	A filter for an airfoil of a vane of a turbomachine is disclosed. The filter includes a mounting member for mounting to an endwall of the vane. The mounting member has a first flow exit opening defined therethrough for fluid communication with a cooling circuit of the airfoil. A screen frame is coupled to the mounting member to support a wire screen around the first flow exit opening, and a first wire screen is positioned over the screen frame. The screen frame has an exterior shape supporting the wire screen in a manner incapable of having a horizontal surface regardless of a circumferential position of the airfoil around an axis of the turbomachine. A related turbine vane and turbine system are also provided.
