Probabilistic model of penetration of biological agents through filtering devices

The human protection issue from biological agents with the help of filtering devices is studied in this article. This issue is actual for all the countries of the world due to the current coronavirus situation. Considering the hypothesis of the ordinariness of the biological agents’ flow and the absence of aftereffects in the filter, the probabilistic model of the penetration of biological agents through filtering respiratory protection devices is designed based on the Kolmogorov differential equation system applied for the adequate protection of medical personnel.
