High Power UVC LED Array from Bolb Inc. Demonstrates 99.95% Inactivation of Airborne Virus

 

Bolb Inc. claims it has demonstrated 99.95% kill rate against aerosolized bacteria and viruses at up to 3,000 liters per minute flow rate with UVC light.

UVC light has been recognized as a universal, future-proof and chemical-free method to effectively combat mutating pathogens such as SARS-Cov-2. Solid-state emitters produced by Bolb Inc. brings benefits such as extremely high surface brightness, compactness, easy scalability, design flexibility and instant responsivity to a market traditionally dominated by mercury lamps.

The tests were performed against aerosolized human coronavirus HCoV-229E, a single-strand RNA virus that is recognized as a surrogate for SARS-Cov-2, and aerosolized bacteria Staph aureus ATCC 6538 in an enclosed air disinfection reference design equipped with a Bolb UVC LED light module featuring 40 W electrical input power and 2.5 W UVC light output power. In a test, single-pass disinfection efficiency of 99.96% was achieved for air flow rate 3,000 liter per minute containing aerosolized Staph aureus. In a separate test, the reference air disinfection unit demonstrated up to 99.95% inactivation against HCov-229E viral aerosol in a 30 m3 (1060 cu ft) volume in 1 hour.
