Since the COVID-19 pandemic became a fact of life, many people have thought a lot about how disease and germs are transmitted – through the air and on surfaces. And some have turned to technology, looking for that extra measure of protection from pathogens.
A number of products use light, claiming that it can vanquish germs that cling to objects. Tech expert Omar Gallaga wrote about these products and their claims. He told Texas Standard that hospitals have used ultraviolet light to disinfect personal protective equipment since early in the pandemic.
“The masks, the gowns – they were putting them in a room with UV light, and that does work to disinfect,” Gallaga said.
Highlights from this segment:
– UV light kills germs on objects, but is dangerous to humans and pets
– Non-UV germ lights work against bacteria, but not viruses like the coronavirus
– Light boxes or vaults can disinfect objects you place inside
