222nm Band-pass Filters Must Be Used to Remove >230nm For AP-UVGI
Safe for skin and eyes – According to most research, far-UVC products are safe for skin and eyes. Far-UVC does not penetrate the outer layer of skin or eyes, so it doesn’t cause any tissue damage.
Constant disinfection – Because Far-UVC is safe for skin and eyes, products can run constantly.
David Brenner directs the Center for Radiological Research at Columbia University, Irving Medical Center in New York City. Over the past eight years, Dr. Brenner and his team have been developing the use of Far-UVC irradiation excilamps. Those lamps neutralize bacteria, bacterial spores, molds, yeasts, and viruses—including SARS-CoV-2.
David Brenner leads the charge for change on a personal note, putting the stamp of approval on filtered versions of excimer lamps emitting between 207nm and 222nm light as safe for deployment in spaces occupied by Active Personnel inside areas undergoing the Far-UVC UVGI decontamination process.
