Abstract: A reusable filter for use in a spray paint booth is advanced which includes a frame supporting a series of equally spaced horizontal vanes. Each vane is formed to have a shape which reduces clogging of the front face of the filter and forces the air stream to make successive directional changes to thereby effectively remove particulates from the air stream. Three sides of the frame are equipped with a bendable lip that provides a fluid tight seal between the wall and the frame. The fourth side of the frame is formed with access holes enabling paint particulates and liquid cleanser to be quickly removed from between the vanes. The filter is made of a polymeric material which is impervious to solids and can be cleaned by any cleaner normally used to remove paint from a surface.
