An air particulate filtration device designed to filter the primary filtration exhaust from a mechanical abrading dust collection device. The filtration device includes a flexible duct used to guide a positive pressure air stream from a mechanical abrading dust collection device into a receptacle partially filled with a liquid and buoyant packing material. The buoyant packing material aids in increasing the surface liquid contact with the positive pressure air stream. The fine dust and particulates that contact the liquid settle to the bottom of the receptacle. The positive pressure air stream passes though a final air filter located near the top of the filtration device after making contact with the liquid surface.
