The refractory filter is heated by the exhaust produced by the incinerator to a temperature above 700.degree. C. to destroy the toxic organic substance in the exhaust. The refractory filter preferably includes a plurality of ceramic cylinders and is periodically cleaned to remove accumulated solid particles on the upstream surface of the cylinders by injecting high pressure air into the cylinders.
