Sensor Electronics Technology Inc (SETi) of Columbia, SC, USA (which makes UV-A, UV-B and UV-C deep-ultraviolet LEDs, emitting at wavelengths of 200-430nm) and UV LED product maker Seoul Viosys Co Ltd (SVC) – both subsidiaries of South Korean LED maker Seoul Semiconductor – say that their Violeds technology has been shown to quickly and effectively kill 99.437% of SARS-CoV-2 coronavirus in less than 1 second. Testing was conducted in December through KR Biotech, a South Korea-based research institute specializing in sterilization testing of the new coronavirus.

The test results demonstrate that Violeds UV LED technology could be an effective method to disinfect airborne viruses, water systems and areas where COVID-19 patients are housed, including hospital rooms, say the firms.

After exposing SARS-CoV-2 to the Violeds UV LED module for 1, 3 and 5s respectively, the research team observed an inactivation rate of virus particles of 99.437% within 1 second.

“The COVID-19 pandemic and the accompanying risk of virus variants continue,” comments Seoul Viosys. “Despite vaccination with influenza vaccines, flu deaths in the US average more than 10,000 per year. As hundreds of millions of people around the world are exposed to various infectious diseases, prevention through disinfection is now an essential method for reducing infections,” it adds. “Due to the hazards of chemical disinfection methods, professionally designed UV LED disinfection systems represent a safer solution and may be the world standard in the future.”

SETi currently has two sample disinfection products demonstrating UV-C LED technology available for purchase at https://violedsstore.com.
