ii.It is a UV-C light based sanitisation box and hand held device (UV light with wavelength 254 nanometres-nm), where the UV-C helps to destroy the genetic material in COVID-19. The radiation controls the Ribonucleic Acid(RNA) structure, which prevents the virus particles from making more copies of themselves.

iii.The UV-C box is designed to disinfect personal items such as mobile phones, tablets, etc. COVID-19 virus is deactivated by using UVC lamps in a minute that are  placed at an equi-distance in a box with a UV dose of 100 mJ/cm2 (millijoule per square centimeter) & the UV lamps used in the sanitisation box also emits 185 nm.

iv.The handheld device is a 8 watt UV-C lamp which disinfects office and household objects like chairs, files, postal delivered items and food packets with an exposure of 45 seconds at a 100 mJ/cm2 irradiance placed at a distance of less than 2 inches.
