Particularly since the beginning of the corona pandemic, there has been a high demand for effectiveness tests of mobile air purifiers. They are increasingly being used in offices and meeting rooms, doctors’ surgeries, administrations, schools, and day-care centres for better virus protection. Of course, the focus is on the question of how effective the air purifiers are and by what standards this can be measured. The VDI has now published the new VDI Expert Recommendation (EE) 4300 Sheet 14 – “Measuring Indoor Air Pollution - Requirements for Mobile Air Purifiers to Reduce Aerosol-Borne Transmission of Infectious Diseases”. The experts at WESSLING conduct tests in compliance with the new VDI recommendation.
For the first time, a uniform and practical test procedure for mobile room air cleaners is defined and requirements for an effective reduction of the virus load are described. This stipulates, for example, that the tests be carried out in a real environment (furnished rooms). The paper was prepared by independent specialists from the DIN Commission “Clean Air” and the VDI Society “Building and Building Technology (BGB)”.
