ABSTRACT: Chlorine dioxide (ClO2) gas is a well-established antimicrobial agent with broad-spectrum efficacy against bacteria, fungi, and viruses. In clinical settings, especially operating rooms and dental clinics, bioaerosol transmission of infectious agents poses significant risks. This study evaluates the effectiveness of ClO2 gas in mitigating airborne microbial contaminants using data from experimental setups, including HEPA filter environments, chlorine dioxide filters, and controlled laboratory conditions. Supported by empirical findings and our previously published studies, this study’s results demonstrate over 99% reduction in airborne pathogens, confirming ClO2’s potential as a critical disinfection strategy in healthcare facilities.
