Desktop air curtain could block viral spread in hospitals

Air curtains to block pathogens in hospitals? Sounds interesting, but is it practical?

"... To protect them from exposure to infections in such scenarios, a team at Nagoya University in Japan has developed a desktop air curtain system (DACS) that blocks emitted aerosol particles and prevents potential spread of viruses such as SARS-CoV-2.

The DACS contains a generator at the top that produces a steady airflow, which is then guided to a suction port at the bottom of the device, effectively creating a smooth curtain of air. ..."
