[Objective] The research aimed to investigate the air quality of public Internet cafes in a university town of Fuzhou, and to analyze the variation of air quality with the change of the month, the morning and evening, and put forward some suggestions to improve the indoor air quality. [Method] There were 4 Internet cafes in Huakang Road, a university town in Fuzhou. Record the indoor structure, area, number of computers and ventilation equipment. Measure indoor air carbon dioxide, formaldehyde, oxygen consumption, total bacteria and microclimate. [Result] The indoor temperature, wind speed and the total number of bacteria in the Internet cafe all met the standard. The highest rate of carbon dioxide exceeded 12.5% in January, the highest rate of formaldehyde exceeded 7.5% in July, and the air oxygen consumption exceeded 100% Night; air quality is related to the change of seasons. [Conclusion] The air oxygen consumption in Internet cafes in the University City exceeded the standard of 100%, while the concentrations of formaldehyde and carbon dioxide exceeded the standards.
