A technical contradiction arises when within a system one parameter improves thus automatically causing another one to worsen. In a situation like this, instead of a usual acceptance of compromise which leads to optimization of a solution for a newly founded problem, in inventology we implement the process of idealisation. The experimental part of this study comprises comparative examination of NaCl aerosol leakage, as a simulator of biological agents, into the epidemiological anti-microbe masks EM1 and EM2, with the aim of determining physiological suitability of EM1 and EM2 and the resistance that arises when inhaling NaCl aerosol was measured at the flows of 95dm 3 /min. It was experimentally proved that impregnation of silver nanoparticles onto the inner filtrating layer of EM2 contributes to the increase of its efficiency, and mathematical modelling helped calculate the realistic increase of this means.
