During the winter semester 2020 the pandemic posed great challenges for schools in particular. In a practical test during regular lessons at the St. Ursula Gymnasium in Aachen, the RoomGuard was able to prove its effectiveness. In the video you can see the importance pupils and teachers attribute to the mobile room filter for aerosols and viruses. “It’s about the students AND the staff. Because if the teachers were to become absent, it would be catastrophic for the running of the school. It is exciting to see what opportunities lie dormant in this technology.  And we want to make a contribution with the field test in our school so that this opportunity can be used in many, many schools”. Explains Headmaster Patrick Biemans.
