Bioaerosols are one of the main causes of diseases and illnesses. Respiratory bacterial and viruses are responsible for some of the world’s most devastating epidemics and pandemics. Therefore, their capture, removal, and disinfection are essential in preventing the spread of diseases. In this work, the photocatalytic and the photochemical inactivation of a model microorganism using in a low-cost and market availably absolute filter was studied. The model microorganism was spread, resembling flügge drops on filters coated with TiO2 and bare filters, then were subjected to different levels of UV-A radiation and different humidity conditions. Results indicate the feasibility of bacterial inactivation with photocatalysis in filtration systems.
