Respirator filtration efficiency
Tolnaj, Tomáš ; Mišík, Ondrej (referee) ; Bělka, Miloslav (advisor)
Aerosols are everywhere around us and pose an increasing risk to human health. That is why aerosols and their filtration are the subject of several researches. This bachelor thesis focuses on established standards for respirator testing according to the European standard and factors influencing their filtration efficiency. The research also includes a description of the theoretical background of aerosols, the physical principles of deposition, a detailed description of respirators. The thesis contains an experimental part, which consists of designing, assembling and setting up the experimental rig with subsequent measurement of the filtration efficiency, pressure loss and evaluation of the measured results.
