Scientific background

Accordingtoexperts,asstatedbyDr.SauterfromtheInstituteofAerosolResearch,filterefficiencyiscrucialforasignificantreductionintheriskofinfectionwhenitis necessary tosignificantlyreducetheconcentrationofviruses,allergensandparticulatematterintheair.

With the aim of minimising the risk of infection in group rooms (and thus protecting students, teachers and school employees), this requirement must be met. This means that a high filter efficiency of at least 99.995% should be given by high separation efficiency of a high-performance filter, e.B. the HEPA high-performance filter H14 according to industry standard. Our study partner Krieg supports us with a test device that meets these technical requirements in order to accompany the study as an example.
