They outline their results in a paper recently published in the journal Advanced Sustainable Systems.

"Especially after going through COVID-19, we know the significance of indoor air quality," said Choi, a faculty member in the Thomas J. Watson College of Engineering and Applied Science's Department of Electrical and Computer Engineering.
