Development and evaluation of a test standard for the effectiveness of air purifiers in reducing the viral load in indoor air

Project start /

The Corona pandemic has demonstrated the importance of protecting people against infection through airborne pathogens in indoor environments. Air-purification systems can significantly contribute towards this. Currently, however, there is no uniform procedure for testing their effectiveness. We are developing a possible test standard in order to close this gap. In the future, this should facilitate the health evaluation of workplaces with regard to viruses and other airborne pathogens.
