Portable device, useful for protecting against droplet infection, comprises a filter surface covering mouth region of person, which carries out disinfection of pathogens in contact region of filter surface by electrolysis

摘要

Portable device comprises a filter surface covering at least the mouth region of a person. The disinfection of pathogens in contact region of the filter surface for ambient air takes place by electrolysis of sodium chloride solution, where the filter surface exhibits a pocket-shaped opening for receiving an electrolysis cell (3), on the side facing away from the contact region of the ambient air.
