The use of UVCs for air and water sanitation has been known for a long time, the first uses for water sanitation, for example, date back to the early 1900s.
With the spread of the COVID-19 SARS virus pandemic, interest in the sanitizing efficacy of UVC beams has increased exponentially, as well as studies on its efficacy.
In this article of the Don Gnocchi Foundation,“Coronavirus, demonstrated the high germicidal power of ultraviolet rays“, a review of the findings of research on the subject.
Another interesting study to read is from Columbia University just on the role of UVCs in preventing the spread of Coronavirus.
It must be said, however, that UVC must be handled with great care, to go from a positive effect to a harmful one for humans is a matter of a few nanometers, so we recommend investigating carefully first, for example by reading this article by some eminent experts.
Photocatalytic filtration is also activated by UVC frequencies and therefore constitutes a truly complete system for air purification and sanitation.
