Does UV C Light Really Kill Germs?

UV Light That Is Safe for Humans but Bad for Bacteria and Viruses.

Scientists have known for decades that broad-spectrum UVC light, which has a wavelength of between 200 to 400 nanometers (nm), is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together.

Does UV C light kill bacteria?

With powerful UV-C light inside, PhoneSoap has a deadly effect on microorganisms such as pathogens, viruses, bacteria, and others. Your phone’s warm battery allows bacteria to thrive and reproduce. UV-C light penetrates the cell and disrupts the DNA, killing the pathogen.

UV however, can be toxic to human cells and both researchers and scientists have devised various ways of incorporating it in air purification strategies.

How effective is UV sterilization?

This is why UV disinfection is sometimes called ultraviolet germicidal irradiation (UVGI). UV has been proven effective against a broad spectrum of microorganisms. Bacteria are generally easier to inactivate than viruses, with fungi and spores being even harder to inactivate with UV.
