Abstract. A process of formation of dust deposition in the multi-layer filter is considered.
A method of calculating the multilayer filter is proposed, which helps ensuring maximum dust depositing and minimum pressure drop at varying diameter and thickness of the fiber layers. Ac-cording to the experimental study of the dust content in the two-layer samples, maximal amount of dust is deposited on the filters, packing density of which is within the range of 0.03-0.06. Parameters were calculated for the new multi-layer filtering half-mask with increased volume for deposition of dust.
Keywords: respirator, protection factor, RPE, occupational diseases, aerosol filter, deposition of dust.
