Using a graphene-based filter, the ViralWall "cleans the air from airborne bacteria and viruses and creates an invisible 1.2x1.6 meter air screen between people to prevent the spread of harmful airborne particles".
The Viralwall is based on a laser-induced graphene filter (produced in Israel by LIGC), that is placed between two contacts. When voltage is applied, the current eliminates germs and viruses (and also helps with smoke, allergens and more).
