Fraunhofer Institute for Wood Research Researchers at the Fraunhofer WKI develop test procedure for the uniform evaluation of air purifiers
The corona pandemic has shown just how important it is to protect people in indoor areas against infection through airborne pathogens. Mobile air purifiers can, in principle, contribute to this. Until now, there has been no uniform method for testing their effectiveness. Researchers at the Fraunhofer WKI have therefore developed a standardised testing method to close this gap.
In collaboration with the Institute of Animal Hygiene, Animal Welfare and Farm Animal Behaviour at the University of Veterinary Medicine Hannover, researchers at the Fraunhofer WKI have evaluated the test methodology for mobile air purifiers by means of a variety of device types. The test method developed can be applied to the various technologies available on the market for reducing the virus load and will be published and available as a DGUV testing principle in the near future.
The study was commissioned by the German Social Accident Insurance (DGUV), the umbrella organization of the German trade associations and accident-insurance companies.
