Remarks and suggestions to the authors of the article
The topic of these studies is extremely relevant. The scientific substantiation of the degree of protective properties of different types of face masks is carried out. The most modern laboratory devices are used for this purpose. The formulation of the experiment is significantly close to real conditions.
An important issue in assessing the protective properties of face masks is to determine their dynamics over time. In addition, an interesting question is - by what percentage increases the protective properties of each subsequent layer in the most commonly used surgical or tissue masks.
