At a press conference at the University of Ruse, Bulgaria was presented a face mask filter, which is designed for individual protection against the penetration of pathogens and viruses like Covid-19 into the respiratory tract of the human body, as well as against their transmission from the user to other people.


The main advantage of the invention is that it significantly limits the spread of pathogens and viruses preventively, as they are deactivated 'under the nose' in both directions - from and to the user.

 The invention provides a design for a face mask filter which is capable to deactivate pathogens and viruses , outside and inside of the filter.
The filter functions as a passive static galvanic cell activated by the air jet and moisture droplets contained in the air during inhalation and exhalation by the user.

Face masks in silver and titanium-only textile versions can be reusable by washing up to 60 °Celsius. 

The nanoparticles that cover the textile fabrics are firmly attached to the fibers and allow the passage of ions with different electrical potential from one layer of coating to another, in which pathogens and viruses contained in the wet drops during respiratory exhalation are deactivated.
