Abstract: The possibility of aerosol contamination of people and the environment with biological agents as a result of terrorist attacks, natural epidemics or war activities, represents a challenge to all subjects involved to emergency responding, healthcare workers and the civilian population. Dealing with it primarily requires the use of respiratory protection devices (RPD). These devices must be made of materials that should fulfill two basic criteria for above mentioned purpose - high efficiency of filtration against bioaerosols and appropriate breathing resistance. Consequently it is necessary to overwiev the interdependency of factors: bioaerosol contamination - RPD - protective efficacy and physiological suitability. The paper presents the possibilities of filtering half masks usage according to the filtration performance of their embedded filtering materials, with special emphasis on the application of nanotechnological achievements for improving their filtration efficiency. It is given a review of the methods of its testing and evaluation for protection against bioaerosols, in the world and in our country. Keywords: respiratory protection, filtrating half masks, filtering efficiency, biological aerosols.
