This invention relates to a process and apparatus for removing fine particulate matter and vapors from a process exhaust air stream, and particularly those emitted during post-production curing or post-treatment of foamed plastics, such as polyurethane foam, in which the exhaust air stream is passed through a transfer duct into which is introduced a water spray in the form of a mist of fine droplets in an amount which exceeds the saturation point; thereafter the exhaust air stream is introduced into a filter chamber having a cross-sectional area that is substantially greater than that of the transfer duct, and the exhaust air stream passes through at least one, and preferably a plurality of high surface are a filters, whereby a portion of the water is removed from the exhaust air stream and collected in the filter chamber prior to the discharge of the exhaust air stream into the environment.
