These days we hear a lot about UV systems against COVID 19. We recommend everyone to read the pages dedicated to this topic of the IUVA.
IUVA (International UltraViolet Association) is the international reference association for UV technology.
As you can read, UV technology is effective if properly sized and used.
We also like to remember, as IUVA also does, to use the maximum pre-caution because the exposure to UVC rays is harmful to the skin and eyes.
