To answer the question of how germicidal lamp works, you first need to briefly explain radiation UVC. It damages the DNA and RNA chains and thus effectively destroys them. This is one of the best air disinfection methods. UVC radiation effectively removes all viruses, fungi, pneumococci, bacteria, and mold. However, you have to be careful, because this radiation also harms people, therefore the safest are virucidal lamps, which have protection against the opening, and their construction allows for effective and safe air purification.
The pandemic has shown us all that germicidal lamps will work anywhere: in public facilities such as schools, clinics, hotels or restaurants, in offices or even private homes. They are often used by doctors in hospitals and other medical facilities.
