FIELD: medicine, life saving equipment.
SUBSTANCE: invention can be used in individual respiratory protection - filter half-mask respirators and small-sized dynamic air cleaning systems. A filter catalytic compound material for air clearing from aerosols and carbon monoxide contains two layers of a fibrous filter medium and a layer of catalytic material. The layer of catalytic material is made of needled felt of surface density 220-250 g/m3, filled is a fine ground palladium-containing low-temperature carbon monoxide oxidation catalyst with particle size to 100 mc in the following ratio, wt %: catalyst - 15-50 %, fibrous filter medium - the rest, and is arranged between the layers of filtering medium made of electrostatic fine-filamented polymer fibres.
EFFECT: enabled humidity operation, reliable catalyst fixation in a layer and carbon monoxide and aerosol protection.
