Résumé

The novel Coronavirus disease (COVID-19) pandemic has driven innovation for the development of new air cleaning technologies with renewed interest in determining effectiveness of both new as well as existing cleaning technologies. Standardized test methods for the evaluation of reactive air-cleaning technologies for both volatile organic compounds (VOCs) and microbiological agents do not exist. Since air movement in a building is very dynamic and situational specific, the lack of standardized methods may lead to contradictory results or sub-optimal evaluation of a device’s performance in a laboratory setting.
In this paper, a graphene enhanced photocatalytic oxidization (GPCO) device is presented and evaluated for general effectiveness against some challenge VOCs. The authors describe the VOC testing methodology used as well as variables that could impact the reproducibility and repeatability of the results. In addition, measurements of various by-products that could have been generated by the device, e.g., ozone, are presented. The results demonstrated that the tested device reduced concentrations of formaldehyde and toluene over time.
