Heraeus’s UV-C air purifiers proven to achieve 99.999% air purification

Study confirms 99.999% air purification with UV-C from Heraeus

Heraeus Noblelight, together with the hygiene institute biotec GmbH, proves the complete destruction of viruses in UV-C air purifiers. The biotec report shows the tested UV-C device eliminates 99.999 percent of the surrogate viruses. “The result exceeds our own expectations and underlines the fact that Heraeus UV-C technology is a very effective technology for combating the Corona Pandemic,” says Martin Ackermann, Managing Director of Heraeus Noblelight, a world leader in specialty lighting applications. In addition no ozone could be detected during the independent qualification.

Log 5 cleaning even at very high air flow

The test examined the inactivation of the RNA virus MS2 after it passed through the UV-C system at a high air flow rate of around 1500 cubic meters per hour. These viruses are used as a surrogate for the corona virus. “The research project carried out shows a very high inactivation rate for the surrogate virus MS2. A reduction by 5 log levels could be demonstrated, which corresponds to an inactivation rate of 99.999 percent”, the biotec study concludes.

“The biotec study also confirms our simulations for installations of UV-C devices in buses”, says Ackermann. “There we proved an inactivation rate of 99.99 percent (log 4) of the viruses in the air within five to six minutes at an air volume flow of 2000 cubic meters per hour – this air flow corresponds to the ventilation system in a typical city bus”.
