Smooth surfaces like marble and glass are easier to disinfect than wood or cloth. Magic Wand? Not Really, Nope!ĭuring the H1N1 influence pandemic of 2009, microbiologists warned that theĭistance and duration that a wand is held from an infected surface are both critical. The same sanitizing energy can also damage eyes and skin, and cause cancer. UV-C carries the most energy capable of destroying the bonds that hold together the DNA and RNA of viruses and bacteria, stopping them from working. Ultraviolet light has been an old friend to the disinfection world for over a century. These three types of UV radiation differ in their biological activity and the extent to which they can penetrate the skin, says Shen. Ultraviolet light, or UV, that heads to earth courtesy of the sun and the electromagnetic spectrum, comes in three main flavors: UV-A ranges from 315 to 400 nanometers, UV-B from 280 to 315 nanometers and UV-C from 100 to 280 nanometers.
“Beware of false claims that say these products are effective, or are safe for use on humans,” says Jung-Tsung Shen, an engineer and physicist at Washington University in St. Since researchers have no idea of the dose, distance or time to disable SARS-CoV-2, these lights could give you a false sense of security. You also risk accidental exposure to dangerous ultraviolet light. Others are of such low power that you’d have to hold the device over an item (say, a mask) for 30 minutes to maybe get any disinfection, much less destroy SARS-CoV-2, the virus responsible for COVID-19. But while a personal UV-C light wand may sound nifty, problems with the wands may outweigh any potential benefits.įor starters, many of them are fakes.
They’re easy to find on sites like Amazon, Sharper Image and eBay.

The product descriptions are certainly alluring - advertised to sanitize everything from mail to computer keyboards, plus makeup brushes, sofas, bedding, toilets and pet areas. Perfect for that weekend trip to the Airbnb. These devices claim to kill 99.9 percent of germs, bacteria and viruses, and they’re lightweight and portable. Dr.If you’ve struggled to find household disinfectants and wipes recently, you’ll understand the allure of UV wand disinfectants.UV-C has been proven to kill strands of coronavirus (below are research studies demonstrating the effectiveness of UV-C light on SARS and MERS). It is widely accepted that it is not necessary to kill pathogens with UV light, but rather apply enough UV light to prevent the organism from replicating. If enough of these dimers are created in DNA, the DNA replication process is disrupted, and the cell cannot replicate. Absorption by DNA or RNA (specifically by thymine bases) is known to cause inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. Using high powered LED’s, the UV Wand allows you to disinfect up to 10x faster than most fluorescent UV devices and the Jacuzzi® UV Wand is up to 2x more powerful than other LED UV devices.Īs evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200 nm to 300 nm, the UV is absorbed by the DNA, RNA, and proteins.Ībsorption by proteins can lead to rupture of cell walls and death of the organism. Many bacteria and viruses are heat, cold and drug resistant, but they are not resistant to Ultraviolet light (UV).Emitting both UV-C at 270 – 280nm and UV-A at 380 – 405nm, the Jacuzzi® UV Wand damages the DNA and RNA in bacteria and viruses rendering them harmless. Sterilizing hand gels, disinfectant sprays and sanitizing wipes are not enough to ensure a healthy environment. Now more than ever it’s important to ensure that the space around us is healthy and safe. Harmful germs and bacteria are everywhere.
