Technical University of Liberec (TUL) has developed a new, more efficient and faster way to produce nano-masks, according to Hospodářské noviny. The machine for their production is still secret. It is not possible to take a picture and the school would not say where it is. TUL's Rector Emeritus David Lukáš said that the product goes from the line at a speed of three to five meters per minute. Nanofiber material catches 90% of viruses.
