Functional and Structural Analysis of Respiratory Protective Filters Against Exposure to Suspended Solid Particles

The aim of this project is to perform a functional and structural analysis of respiratory protective filters exposed to suspended solid particles. The study examines how particle size and electric charge influence retention, highlighting the need to adapt filter selection to the specific dust profile of the working environment. Changes in filter porosity between classes and after use are evaluated to predict clogging processes, while reductions in air permeability following dust exposure are assessed to estimate the effective service life of the filters.
