The mechnism of “VirusClean” is a synergistic effect of copper, which has antibacterial and antiviral effects, and a photocatalyst that decomposes organic substances.

Viruses adhering to the glass surface on such as buildings, showcases, partitions, etc., can be removed by indoor light such as fluorescent lights by the effect of “VirusClean” and more than 99% virus activity can be reduced in approximately 60 minutes.

Please see the comparative experiment of virus suppression effect.
This is an experiment using bacteriophage Qβ equivalent to viruses.

There are bacterial-phage Qβ as black spot. You can see how the virus activity is being suppressed on “VirusClean” as the number of viruses decrease over time by applying fluorescent light.
