    • A partially enclosed structure having an inclined wall which is provided with a plurality of ports for admitting grease-laden vapors. Baffles extend internally from each of the ports and are employed to direct the incoming vapors through filter material disposed within the structure. A spray header is disposed above the filter material and a submersible pump in the lower portion or reservoir of the structure forces cleaning solvent through the header where it is sprayed on the filter material to cleanse it of grease and oil. The baffles prevent the cleaning solution from flowing out of the ports in the inclined wall and all of the solution is returned to the reservoir and recirculated. A water supply line and float valve are employed to maintain a predetermined liquid level in the reservoir. The inclined, ported surface of the structure is designed to fit closely adjacent a cooking surface to effectively gather grease-laden vapors and the reservoir is designed to fit in the spacing between the stove and kitchen wall. In a modification, the structure is made in two adjoining sections to facilitate construction and servicing.
