Just for clarify based on researcher that i found its true UVC can reduce in the ambient level of airborne virus .
As i quote on journal :Thus continuous airborne disinfection with far-UVC light at the currently regulatory limit would provide a major reduction in the ambient level of airborne virus in occupied indoor environments.Buonanno, M., Welch, D., Shuryak, I. et al. Far-UVC light (222 nm) efficiently and safely inactivates airborne human coronaviruses. Sci Rep 10, 10285 (2020).
Can it be more discuss more not just based in artikel thats explain about UVC but the real research about the effect of UVC on virus. I think its more be clear again before sub category as HOAX
