A filter for use in a dry powder spray booth that includes a frame containing a quantity of pleated filter sheet material. The ends and sides of the pleated sheet are secured in the frame by a sealant. The material forming the pleated sheet is a fiber paper having a smooth and rough side and is treated with a flame retardant coating. The surface area of the pleated sheet is varied between five and ten times the interior area of the frame. The smooth side of the fiber paper faces upstream with respect to the air flow and the filter is positioned at an acute angle to the vertical with the top inclined upstream. The frame is provided with a manual vibrator and an expanded wire mesh on the downstream side.
