A pool vacuum filter bag for use in combination with a submersible pool vacuum unit is formed of a pair of mesh layers joined by a plurality of sewn seams to form an integral closed filter bag having a elongated flow chamber and an elongated closed end debris chamber. An upper chamber joins the debris chamber and the flow chamber and a mouth portion is adapted to receive and secure attachment to the discharge port of a pool vacuum unit. The upper seam of the filter bag is formed by a joined pair of hook and pile Velcro-type fastening strips and means are provided for securing the filter bag in an upright position parallel to the pool vacuum unit water supply hose. The filter bag includes a curved flow directing portion which reduces accumulation of debris within the flow chamber and enhances debris collection performance. The filter bag may be turned inside-out for cleaning while still attached to the discharge port of the pool vacuum unit.
