UVC light has also been shown to inactivate the genetic material in other coronaviruses. UV-C has been proven to kill bacteria and viruses. In a few laboratory experiments, UVC light has been found to destroy the ability of the SARS-CoV-2 virus to infect a host (for example, a mouse or a person), another indication that it is effective against germs. That means if the beam of light is blocked by dust, dirt, small crevices, or any other impediment, it may not be fully effective. Devices without high wavelengths or UV-C light, may not sanitize every day products at all. The light needs direct exposure to kill the coronavirus.

Plus, both varieties of sanitizing lights keep gunk from building up and moving through your HVAC system. These lights can also kill off volatile organic compounds (VOCs), which cause odors like tobacco smoke. The thing about UV light is that it has sufficient energy to cause damage to cells, DNA, and other biological material, which can make it a powerful disinfectant against viruses and bacteria. UV lights target germs that can worsen conditions like asthma and COPD. That's because UV light kills up to 99.9 percent of germs, bacteria, and viruses-and that may include the coronavirus. How UV Light Kills Germs UV radiation kills viruses and bacteria by damaging their genetic material (DNA and RNA). But now you may be noticing that same technology for sale in places like Costco and drugstores. SAN FRANCISCO (KGO) - Ultraviolet technology isn't new it's been used in hospitals, research labs, and other areas that need to be germ-free. But before you stock up on UV lamps, there are some things you should know.
