Cooking aerosol treatment was a significant part of the ventilation system in the commercial kitchen, for reducing the emission of particulate matter (PM) and volatile organic compounds (VOCs) in cities. This study was comprehensively reviewed the research progress, the standards and policy of major global regions and the recent development of purifying methods, which was included: (1) wet method, (2) photolysis oxidation method, (3) physical interception method, (4) electrostatic adsorption method and (5) integrated purifying practice. Based on an extensive test of purifying devices, it analyzed the performance parameters of this method, and introduced the mechanisms, the individual characters, the merits and demerits of these purifying methods. According to the data statistics of test reports, it was found that the integrated purifying devices which was based on the electrostatic adsorption method received considerable attention because it had the high and stable purifying capacity and more straightforward installation. The suggestions and prospects for future researches were finally proposed. This review might be used for inspiration in developing novel technologies for cooking aerosol treatment.
