Abstract: In many countries of the world, the need to take preventive measures against aerosol contamination and the spread of biological agents has been recognized. The main role in these efforts is taken by means of personal respiratory protection devices. Accordingly to this, it is necessary to have information about the characteristics and qualities of the filtering materials which are embedded in mentioned products. The methodologies for testing and evaluation of filter materials are based on monitoring parameters that are emphasized in the aerosol filtration mechanism, primarily the aerosol contaminant inward leakage towards the interior of protective means, efficiency and dynamics of aerosol contaminants filtration through filtration medium, along its appropriate physiological suitability. This paper presents a review of the methods which are used directly and indirectly for testing and evaluation of products for personal respiratory protection against bioaerosols, in the world and in our country.

Keywords: filtering materials, testing methodologies, respiratory protection devices, bioaerosols.
