FIELD: production processes.
SUBSTANCE: invention refers to fine purification of air from particulate pollutants and gases, from carbon monoxide in particular by means of nonwoven filter materials. Presented multilayer filter material from polysulphon consists of three layers, at that second (working) layer is made of fibers with diametre from 5 to 9 mcm, with surface density 40-50 mg per cm2, free volume from 95 to 98% and average dimension of pores is from 20 to 40 mcm, surface density of first and third (protective) layers is 15-30 mg per cm, they are made of fibers with diametre 1-3 mcm, with free volume from 94 to 97% and average dimension of pores is from 4 to 12 mcm.
EFFECT: invention ensures possibility of effective inclusion of dispersed phase with sorbing or catalytical properties in filter material structure.
