The manufacturer does make sure to specify that the wand is certified waterproof. As the researchers explained, broad-spectrum UVC light kills viruses and bacteria, and it is currently used to decontaminate surgical equipment. The product features a child safety lock and an auto-shutoff feature if the wand isn't shining downward, but a misleading chart at the top of the product listing comparing the wand's LEDs to other types of UV lamps wrongly claims that the light comes with no side effects. In this new study, they found that far-UVC light also killed airborne H1N1 virus, a common strain of flu virus. Two flu experts were encouraged by the findings. ", Many of the products currently being sold seem to downplay that risk, or ignore it altogether. However, Brenner and his colleagues wondered if a much narrower spectrum of ultraviolet light, far-UVC, might be a safer option. In the meantime, research continues into the potential efficacy of UVC light against the virus that causes COVID-19. UL is unwilling to certify wands like those due to the high risk in an uncontrolled home setting. "And unlike flu vaccines, far-UVC is likely to be effective against all airborne microbes, even newly emerging strains," he said. There has to be some time for the device to be in place for it to be able to do the work it's intended to. If Walmart learns that a supplier is providing non-compliant items, those items are promptly removed from sale. 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. There's no mention of safety certification other than 3C certification via Chinese regulators, either. "So it may take several days before you realize you've damaged your eyes or caused burns on your skin. Be respectful, keep it civil and stay on topic. Always consult a physician or other qualified health provider regarding any questions you may have about a medical condition or health objectives. ... † PhoneSoap 3 has been laboratory tested against common household bacteria. It's already making its way into homes, businesses and schools across the country. 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. 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. Natural UVC light from the sun is completely absorbed by the Earth's atmosphere. "Unlike chemical pesticides, EPA does not routinely review the safety or efficacy of pesticidal devices such as UV lights. "There are installers and commercial-grade products out there that do have a safety certification and which can be installed and used very safely.". "The damage that's being done is also not instantaneous," Gwynn adds. ", "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. Researchers say a certain spectrum of ultraviolet light -- called far-UVC -- easily kills airborne flu viruses while posing no risk to people. We delete comments that violate our policy, which we encourage you to read. Testing was performed on phones as well as other small objects. 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. 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. That has some consumers and product manufacturers turning to ultraviolet, or UV light as a potential solution -- specifically, a type of UV light called UVC, which has extra-short wavelengths and enough energy to alter the DNA and RNA of organic cells, which stops them from reproducing.

Amazon didn't respond to a request for comment, though its product listings note that the company assumes no liability for inaccuracies or misstatements about products. Signify, formerly Philips Lighting, which has been producing UVC lighting for more than 35 years, tells CNET that interest in the lights has spiked enough to justify an eight-fold increase in production since the start of the pandemic. 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. The coronavirus pandemic has businesses and homeowners alike seeking out anything that might make shared spaces feel safer and more sanitary. All rights reserved. "This is a hazard you can't see," explains Pamela Gwynn, principal engineer for UL's Life and Health Sciences related to medical equipment. "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. ALL RIGHTS RESERVED. This use can sterilize the air in a public space, reducing the spread of respiratory droplets containing flu viruses and other bacteria and viruses.". "These can be very dangerous if you don't use them properly.". WebMD does not provide medical advice, diagnosis or treatment. 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. That's where safety experts are beginning to sound the alarms. "Immunization and antiviral medications are also important, but again, have limitations.
