That gave manufacturers a green light to begin marketing potential COVID killers. There's no mention of safety certification other than 3C certification via Chinese regulators, either. "An EPA establishment number on a pesticide device label identifies the EPA-registered location where the product was produced," an EPA spokesperson tells CNET. Always consult a physician or other qualified health provider regarding any questions you may have about a medical condition or health objectives. And, as an observant CNET reader pointed out, Amazon has it categorized under "Hand Sanitizers.".

UL's reference guide for UVC devices notes the "serious risks" associated with UVC exposure. Elsewhere, one recent study out of Columbia University looked at "far-UVC" light that shines at a less intense wavelength -- still strong enough to zap viruses, but potentially incapable of penetrating eye and skin tissue. Being listed in that database does not certify that the company's product is safe or effective for use in the home. "Immunization and antiviral medications are also important, but again, have limitations. It could offer a new, inexpensive way to eliminate airborne flu viruses in indoor public spaces such as hospitals, doctors' offices, schools, airports and aircraft, said the team from Columbia University Medical Center in New York City. The Haiku UV-C smart ceiling fan from Big Ass Fans uses built-in UV light to disinfect air as it circulates throughout the room. Be respectful, keep it civil and stay on topic. That's where safety experts are beginning to sound the alarms. Check availability at Walmart, Amazon, Best Buy and more, Kirk McKoy/Los Angeles Times/Getty Images, Discuss: UVC wands kill viruses. ... † PhoneSoap 3 has been laboratory tested against common household bacteria. While scientists are still working to determine the full efficacy of UVC light against SARS-CoV-2, the coronavirus that causes COVID-19, the early indications are promising -- enough so that the FDA issued guidance in March that it "does not plan to object" to any previously cleared sterilization or disinfectant devices updating their marketing to indicate that they combat COVID-19. In an age when Clorox wipes are a precious commodity, sanitizing UVC light might seem like a promising alternative. The invisible light can kill viruses and pathogens like the one that causes COVID-19, but experts are raising alarms about the potential safety risks. "Because disinfection kills most recognized pathogenic microorganisms, it can generally be inferred that sterilization and disinfection should minimize the viability of SARS-CoV-2 on surfaces and in the air in confined spaces," the FDA wrote. Researchers say a certain spectrum of ultraviolet light -- called far-UVC -- easily kills airborne flu viruses while posing no risk to people. For the most up-to-date news and information about the coronavirus pandemic, visit the. "The risk may increase if the unit is not installed properly or used by untrained individuals. UVC light is ultraviolet light that falls specifically between 180 and 280 nanometers -- the shortest, most intense part of the ultraviolet light spectrum. EPA certification only signifies that the company making the device has registered with the EPA, and is listed in its database of companies who make products that include an active pesticide. SOURCES: Michael Grosso, M.D., chair, pediatrics and chief medical officer, Huntington Hospital, N.Y.; Len Horovitz, M.D., pulmonary specialist, Lenox Hill Hospital, New York City; Columbia University Medical Center, news release, Feb. 9, 2018, Smart Grocery Shopping When You Have Diabetes, Surprising Things You Didn't Know About Dogs and Cats, Coronavirus in Context: Interviews With Experts. "We know that UVC is a proven way to help eliminate dangerous bacteria and viruses in water, air and on surfaces," says Karen Willis, NEMA's industry director for lighting systems. As the researchers explained, broad-spectrum UVC light kills viruses and bacteria, and it is currently used to decontaminate surgical equipment. One other word of caution here: Beware of products that claim "EPA certification" as some form of reassurance about safety or efficacy. With names like "Germ Guardian," "Bio Shield" and "The Germ Reaper," most claim to kill 99.9% of viruses and other pathogens they come into contact with. "There are installers and commercial-grade products out there that do have a safety certification and which can be installed and used very safely.". "At this point, though there are some promising studies, it's not yet widely determined that [far-UVC light] is indeed safe," says Gwynn. ", "There are emerging studies to understand the effectiveness of UVC against COVID-19," Straka adds, "but in terms of research, there's a lot still pending on that. This UVC wand is sold by Walmart for $20. Similar tests for the Haiku UVC ceiling fan from Big Ass Fans produced encouraging results, with independent researchers finding that the fan was able to reduce the presence of SARS-CoV-2 released into a test chamber by 99.99% within 20 minutes. But this type of light can cause skin cancer and cataracts, so it's not used in public spaces. In this new study, they found that far-UVC light also killed airborne H1N1 virus, a common strain of flu virus. We delete comments that violate our policy, which we encourage you to read. Run a quick search for "UVC" on Amazon or at Walmart and you'll find page upon page of products that promise to sterilize your home. Experts warn they're also a 'major safety issue', Disney Plus hits 73.7 million subscribers, as a natural disinfectant against bacteria and viruses, where UVC products are tested for safety certification, its database of companies who make products that include an active pesticide, killed up to 99% of the virus within seconds. "And unlike flu vaccines, far-UVC is likely to be effective against all airborne microbes, even newly emerging strains," he said. One of the sponsored products at the top of Amazon's search ranks is a UVC light wand from a company headquartered in Shenzhen, China called 59S. How Long Does Coronavirus Live On Surfaces?

Therefore EPA cannot confirm whether, or under what circumstances, such products might be effective against viruses such as SARS-CoV-2, the virus that causes COVID-19. Man-made UVC light is just as intense, and just as good at ionizing organic molecules and altering their DNA and RNA. All rights reserved. Those are all high-end, commercial-grade products -- but interest in cheaper, simpler UVC products that people can bring into their homes is on the rise, too. Straka and other safety science experts at UL recently teamed with the National Electrical Manufacturers Association and the American Lighting Association to address these concerns in a two-page position paper (PDF) outlining the potential risks of using uncertified UVC devices. Devices like those are nothing new, but the pandemic-borne surge of interest in them is raising alarms, because UVC light is a known carcinogen, and even a few moments of direct exposure can be hazardous to the eyes and skin. The pandemic has also produced a flood of cheap, unregulated, consumer-facing devices for use in the home, including handheld wands that let you wave exposed UVC light across items and surfaces. Natural UVC light from the sun is completely absorbed by the Earth's atmosphere. WebMD does not provide medical advice, diagnosis or treatment.

Another wand listed on Walmart features no child lock or auto-shutoff at all, and the listing never warns of any hazard to the eyes or skin -- though it does boast of lights that are twice as intense as a previous model. ", Many of the products currently being sold seem to downplay that risk, or ignore it altogether. How to use a UV light to kill germs at home UVC lights available to consumers come in various forms, including boxes, bottles, and covered wands. Dr. Len Horovitz, a pulmonary specialist at Lenox Hill Hospital in New York City, agreed. "Under the pandemic, we've seen a great increase in the interest around UV germicidal-type devices, including those that are now more consumer-facing," says Todd Straka, global industry director of lighting at Underwriters Laboratories, where UVC products are tested for safety certification. "This is a hazard you can't see," explains Pamela Gwynn, principal engineer for UL's Life and Health Sciences related to medical equipment. The invisible light can kill viruses and pathogens like the one that causes COVID-19, but experts are raising alarms about the potential safety risks. Here's what you need to know -- the science, the safety risks and everything experts say you should take into consideration before bringing any UVC-powered light source into your home. "UVC lamps used for disinfection purposes may pose potential health and safety risks depending on the UVC wavelength, dose, and duration of radiation exposure," the guidance reads. However, Brenner and his colleagues wondered if a much narrower spectrum of ultraviolet light, far-UVC, might be a safer option. Straka calls the situation "a major safety issue," and his counterparts at NEMA and the ALA agree. The manufacturer does make sure to specify that the wand is certified waterproof. "Companies selling pesticide devices that claim their product is 'EPA-approved' or 'EPA-certified' are making false and misleading claims," an EPA spokesperson adds. In prior studies, they found that far-UVC light killed methicillin-resistant S. aureus (MRSA) bacteria -- a common and dangerous "superbug" -- without harming human or mouse skin. Lamps with this type of UV light currently cost less than $1,000, Brenner said, but that price would likely fall if the lamps were mass-produced. ALL RIGHTS RESERVED. The disinfecting success of initial experiments still need to be confirmed, said lead research David Brenner. The biggest concern, UL's experts say, are uncontained devices like light wands that could potentially expose a user's eyes or skin to the invisible UVC light at close range, causing damage. Researchers at Boston University found that Signify's wall-mounted UVC lights killed up to 99% of the virus within seconds; the company is now broadening its portfolio of UVC luminaries for commercial environments. The findings were published online Feb. 9 in the journal Scientific Reports. In Kansas, Digital Aerolus developed a UVC drone that can fly through contaminated spaces disinfecting everything it comes across. Unlike less intense UVA and UVB light, which will burn your skin if you sit out in the sun too long, UVC light can burn skin within seconds.
