UVC LEDs from the US manufacturer Bolb achieve a 99.95% kill rate for airborne viruses and bacteria. This has been confirmed by the Guangzhou Institute of Microbiology.
The tests were conducted, among other viruses and bacteria, on aerosolized multidrug-resistant Staphylococcus aureus (MRSA). In a closed air-disinfection reference design, the researchers used a Bolb UVC LED light module with an electrical input power of 40 W and a UVC output power of 2.5 W. At a flow rate of up to 3,000 liters per minute, this air disinfection device achieved an inactivation rate of 99.95%.
Independent laboratories had previously demonstrated its high efficacy in surface and water disinfection applications. For the human Corona virus HCoV-229E, a single-stranded RNA virus recognized as a SARS-CoV-2 surrogate, and MRSA, inactivation of up to 5-log (99.999%) was demonstrated after only a short time. These tests have been performed – among other institutes – by the Analytical Lab Group in the U.S. state of Minnesota, the University of California at Berkeley, and the Guangzhou Institute of Microbiology in China.
Bolb uses a proprietary epitaxy platform in the manufacture of its solid-state emitters. The UVC LED chips produced in this way boast high efficiency, compactness, ease of scalability, design flexibility, and immediate responsiveness.
“The tests demonstrate the scalability of the technology for air disinfection,” said Dr. Olga Stroh-Vasenev of LASER COMPONENTS, Bolb’s distributor in Europe and North America. “We can envision disinfection solutions on many scales. This ranges from vehicle interiors to restaurants to retail stores. Of course, this especially applies to healthcare applications.”
