The range of ultraviolet light (UV) in the electromagnetic radiation spectrum extends from 10 nm to 400 Nm. Depending on wavelength and exposure time, UV radiation can damage the eyes and skin. UV rays are divided into three classes, UVA (320-400 nm), UVB (290-320 nm) and UVC (200-290 nm) according to wavelengths in the electromagnetic spectrum. The decreasing wavelengths correspond to higher frequency radiation and higher amounts of energy per photon.UVC, germ-killing ultraviolet (UV) light, kills viruses when they are in the air and on surfaces exposed to UVC light rays, reducing the airborne transmission of viruses from person to person. UVC lamps can kill 99.9% of most viruses, bacteria, yeast and mold spores and help prevent future mold formation.

Devices developed by YAZKAR are installed in the "re-circulating air" compartment of air conditioning units. These devices disinfect internal air from viruses, bacteria such as Covid-19, which circulate freely in the air, while also cleaning mold, bacteria and dust deposits formed in the serpentines, providing excellent air quality and reducing maintenance costs. Everyone in the environment is protected from viruses and enjoy fresh air.

UV radiation from the sun kills viruses by chemically altering their genetic material, DNA and RNA. Therefore, UV radiation is defined as the basic natural virus killer in the environment. UVC radiation refers to wavelengths shorter than 280 Nm. These wavelengths are completely absorbed by our atmosphere, and natural UVC radiation cannot reach the surface of the earth. These wavelengths can be obtained for us through artificial sources such as UVC LEDs or mercury lamps. Because UVC light is a high intensity light, UVC light effectively kills pathogens and microorganisms by damaging their DNA, making them non-reproducible (non-reproducible), which leads to cell death. Viruses can be transmitted through person-to-person contact, through biological and non-biological vectors, through contact with fomites that host viral pathogens, or through aerosol droplets. Since Viral pathogens are known to remain on inanimate surfaces, manual disinfection of these surfaces is very important.It helps to eliminate microorganisms present in the environment using disinfection technologies such as UV-C.
