Objective To study the efficiency of the compound active carbon filter in reducing the content of free radicals in the smoke of cigarettes. Methods 9 trademarks of cigarettes installed the compound active carbon filters were collected and ESR was used to analyze the content of free radicals in the particle and gas phases. Results The results showed that the efficiency of the compound active carbon filters to reduce the content of free radicals in the cigarette smoke was not identical,some samples even showed an inverse result.
