Abstract: This paper briefly describes the hazards of volatile organic compounds (VOCs) in vehicles, introduces the current standards of air purifier and air quality for passenger car and sedan. The delayed evaluation method and the comparative evaluation method are proposed,according to the shortcomings of existing standards, and the two methods analyzed for the advantages and disadvantages. The test results of the two methods are analyzed and discussed, the air purifier is evaluated. It provides a scientific basis for enterprises to choose air purifiers, and advocates the concept of leading enterprises to implement healthy travel. The proposed delay evaluation method can be combined with the test method of air quality in the bus, and it is not necessary to test the removal rate of VOCs by the air cleaner separately, which saves time and testing costs for enterprises.

Key words: Volatile organic compounds; Air cleaner; Delayed evaluation method; Comparative evaluation method; Removal efficiency
