Helmet with air curtain: a reliable defense against viruses

Engineers from the University of Michigan have developed a special helmet with an “air curtain” system.

It is able to prevent airborne germs and viruses from entering the respiratory tract.

The system has a device located in the backpack that purifies the air.

It feeds it down through nozzles on the helmet, forming a barrier around the user’s face.

This technology uses cold plasma to kill up to 99.8% of airborne pathogens.

This provides additional protection for agricultural and industrial workers where the risk of infection is high.
