What is UV-C?

UV-C radiation is a cost effective and safe method to sterilise many everyday items


UV-C is a subset of the UV light spectrum. Artificially produced UV-C is used in Ultraviolet germicidal irradiation (UVGI) and has been a staple method of sterilisation against pathogens for over 60 years. The medical industry specifically is one of the primary users of UV-C sterilisation.

UV-C at a specific wavelength, 254 nanometers, is used to inactivate H1N1 influenza and other corona viruses, such as severe acute respiratory virus (SARS-CoV) and Middle Eastern Respiratory Syndrome (MERS-CoV)


The use of light as a sterilisation method has many advantages over chemical methods.

  • UV sterilisation is a non-contact process which eliminates the use of alcohols and other chemicals, reducing the risk of long-term medical effects and ensures the safety of the user.

  • Everyday items such as electronics, clothing, and paper cannot easily be cleaned with alcohol, due to the damaging effects on these items.

  • When engineered correctly, UV sterilisation devices are more efficient, since the level of sanitation is not dependent on the skill of an individual.
