Abstract: Soon after the outbreak of the coronavirus crisis in the Czech Republic and the first lockdown (2020), we enthusiastically decided to fight the coronavirus with scientific \nmeans. Originally materials engineers, we decided to develop an effective protective respiratory device, which was in short supply at the time. We soon found out, that every textile material (handkerchief 10%) has a certain ability to catch an aerosol particle carrying the corona virus, the slower the aerosol particle (d<300 nm) passes through the filter, the greater the chance it has of being caught, with the thickness of the filter, the amount of passed particles decreases exponentially and breathing resistance increases linearly. On this basis, we decided to experiment with a large-area filter placed on the user's back (it wouldn't fit anywhere else) and commercially available textile filter material.
