Abstract Virus‐laden aerosols play a substantial role in the spread of numerous infectious diseases, particularly enclosed indoor settings. Ultraviolet‐C (UVC) disinfection is known to be highly efficient method for disinfecting pathogenic airborne viruses. Recent recommendations suggest using far‐UVC radiation (222 nm) emitted by KrCl* (krypton‐chloride) excimer lamps disinfect high‐risk public spaces due lower exposure risks than low‐pressure (LP) mercury (254 nm). This study experimentally explored comparative effectiveness and germicidal UVC inactivating virus‐laden different protective vector media an air chamber. The inactivation performances individual filtered lamp LP were determined bacteriophages, MS2 (icosahedral non‐enveloped ssRNA virus) Phi6 (spherical enveloped dsRNA aerosolized from artificial human saliva or sodium chloride magnesium sulfate (SM) buffer as media. Disinfection efficacy evaluated concentrated viral aerosols, which replicate those exhaled infected individuals remain suspended deposited on surfaces fomites. Our results show that could greatly accelerate bioaerosols formed SM buffer. In case 222 nm exposure, exhibited significantly more susceptibility whereas showed comparable vulnerability both However, 254 demonstrated greater offers valuable insights improves our understanding influence environments. These findings can guide deployment devices contribute mitigating transmission
