Bioaerosols are the leading cause of diseases and illnesses, andrespiratory bacterial and viruses are responsible for some of theworld’s most devastating epidemics and pandemics. Therefore,their capture, removal, and disinfection are essential in preventingthe spread of diseases.In this work, the photocatalytic and the photochemical inactivationof a model microorganism in a low-cost and market availablyabsolute filter, was study. The model microorganism was spread,resembling flügge drops on filters coated whit TiO 2 and barefilters, then were subjected to different levels of UV-A anddifferent humidity conditions.Results indicate the feasibility of bacterial inactivation withphotocatalysis.
