The subject area of this work refers to filtration process by using fibrous filters made by modified melt-blown technique during simultaneous exposition to contaminated gas by solid particles and liquid microdroplets. The paper consists a characteristics of deposition of aerosols with different morphology and influence for pressure drops for separation solid, liquid and mixed aerosols on fibres. In this research a filtration test set-up was modified to allow to generate and put into airstream simultaneously both particles and droplets
