Manufacturer Independent Air Cleaner Tests

Intermittent ventilation makes sense, but is not enough to really reduce the viral load in classrooms, offices or restaurants, for example. Ventilation is only physically efficient when there is a large temperature difference between inside and outside or when it is actually quite windy outside. Frankfurt atmospheric researchers therefore recommend the use of highly efficient room air purifiers in addition to shock ventilation. For a week you tested four air purifiers in a school class with teachers and 27 students. The result: 30 minutes after switching on, an air purifier had removed 90 percent of the aerosols from the air. The risk of infection with SARS-CoV-2 viruses can therefore be significantly reduced. Now the atmospheric researchers want to find out: are these devices also suitable for other locations? And which is the most efficient way to remove the aerosol from the room air? What else could improve the air purification process? The results of the study should enable concrete recommendations and concepts that make being together in closed rooms safer - regardless of manufacturers and commercial providers. "If several people stay in a room for a long time, then air purifiers are an important part of a safety concept in order to reduce the risk of corona infection from aerosol particles. If the air flow through the device is high enough, you can use relatively simple Means achieve a great deal. "
