Abstract
A smoke exhauster comprises a filtration member of a rectangular framelike construction. The filtration member is disposed in the smoke exhauster such that the periphery of the filtration member urges the inner wall of a stopping portion of the base board of the smoke exhauster, and that the top and the bottom of the filtration member are attached respectively to the bottom of the bottom board of the smoke exhauster and the top of a main plate portion of the base board of the smoke exhauster. The filtration member serves to purify the fume so as to reduce the discharge of the air pollutant into the atmosphere.
