The pilot project with air filters in the class of Professor Bert Blocken, Professor of Building Physics at KU Leuven and Eindhoven University of Technology, and virologist Marc Van Ranst (KU Leuven) can count on so much support that registrations are completed after a few days. More than thirty municipalities and schools are interested. This is reported by Gazet van Antwerpen on Wednesday.

Professor Blocken has been advocating good ventilation in schools for more than a year. In the meantime, he is also focusing on air purification: with air filters he wants to remove the damned particles from the air in which the corona virus can hitch a ride for meters and hours into other people’s lungs. A test in Staphorst in the Netherlands shows that after the air filters were installed, no more infections were found in the schools, the newspaper writes.

“You can believe in coincidence, and the relapse of infections is always due to several factors. But if they fall to zero and stay there, then that is not a miracle, but partly the result of air purification,” explains Professor Blocken in the newspaper. . “A HEPA13 filter, for example, removes 99.95 percent of all particles from the air that are larger than 0.3 micrometers. The virus is smaller, but is almost always on a core – the aerosol particle – that is larger. A good air filter removes 95 percent of those aerosols from the air.”

After the research from the Netherlands became known, the professor started a research in Flanders together with Professor Van Ranst. Now that more than 30 municipalities and schools are showing an interest, they are closing the applications. Air purification will be tested throughout the spring and the contamination figures will be monitored. Professor Van Ranst measures the virus load in the classroom air. “In principle, air purifiers remove all respiratory viruses from the air. We test whether they work properly and whether they are safe,” says Professor Blocken.
