UV gadgets for killing viruses come with limitations, experts say
SAN ANTONIO โ Can ultraviolet products made for home use kill the coronavirus that causes COVID-19? However, they warn the low-dose products sold at stores have limitations and come with a risk. Using ultraviolet light to sterilize is nothing new. UV light has been shown to kill many bacteria and viruses, and that may very well include the novel coronavirus. If dust, dirt or even small crevices block the beam, the UV light may not be fully effective.
