UVC light has a long and well-documented history of use in killing germs -- and has been shown to be effective against coronaviruses -- but its dangers and lack of regulation create roadblocks to widespread home use.
, are meant for at-home use. There are several portable UV sanitizing devices whose manufacturers claim they kill 99.9% of bacteria and viruses on phones, pacifiers, and other surfaces that can get contaminated.
It is unlikely that just quickly scanning a surface with a hand-held device will do any significant damage to viruses or bacteria, he says. Companies that specialize in UV products exclusively have come out with new products in the last few months marketed for use against COVID-19, though no conclusive research has been done. UV Angel, a pathogen control company in Grand Haven, MI, unveiled two products in April and has seen a huge uptick in interest from markets outside the health care realm.We've had a 100% increase in interest -- normally we'd primarily deal with hospitals and doctor offices.
Far-UVC’s wavelength is shorter than conventional germicidal wavelength -- about 222 nanometers, rather than 254 nanometers. Brenner was studying this type of light to killAlthough it is possible to use UVC when people are out of harm’s way -- as hospitals have done in operating rooms after hours, and New York’s Metropolitan Transit Authority is doing on subways -- there needs to be an effective way to use this technology while people are around to help reopen the economy, Brenner says.
“In terms of the back end, things are rapidly speeding up,” he says. “In February, if you wanted to buy some of these UV products, you couldn't. If you wanted to now, it's difficult -- but by the end of the year, it’ll be much more feasible. The companies are stepping up fast.”Check to see if the device has a track record in home medical device disinfection, such as disinfectingmasks, or if it has a commercial track record, such as being used to decontaminate DNA samples in a lab.
