The primary route of transmission of COVID-19 disease is associated with the inhalation of airborne SAR-CoV-2 coronavirus exhaled by infected persons. Therefore, the use of facemasks has been proposed as one of the basic means of protection. This study presents methods of the evaluation of the protective properties of the masks at various exhalation conditions. The preliminary results show that even high-quality masks (respirators) offer only a partial elimination of aerosol particles due to the tightness issues.
