If the aerosol and droplet shielding ratio of PAPR is perfect (RS,in=1), wearing PAPR will reduce the probability of infection by means of aerosols and droplets in the supply air by 100% (RI,i=1). 2. If the aerosol and droplet shielding ratio of PAPR is nothing (RS,in=0), wearing PAPR will reduce the probability of infection by means of aerosols and droplets in the supply air by nothing (RI,in=0). 3. In the intervals of 0 For the exhaust side, the following can be said. 4.
