The Lepestok-200 respirator is recommended to be used if hazardous aerosols with a size of less than 1 micron containing up to 200 maximum concentration limits are contained in the air. It can also be used to protect against aerosols and more than 1 micron, but in this case, the use of respirators "Lepestok-40" or "Lepestok-5" is preferable, since they with the same particle efficiency of more than 1 micron have less breathing resistance. The respirator ШБ-1 "Lepestok-200" is recommended for use at the enterprises of Rosatom. Also, the ShB-1 respirator “Lepestok-200” can be used when working in mining, metallurgical, alumina and similar plants, asbestos factories, in the production of mineral fertilizers, in the milling industry, in mechanical engineering, shipbuilding, woodworking, agriculture, repair and cleaning of premises, dedusting of carpets and clothes,
Structurally, respirators are designed as a filter half mask, in which the filter element serves as the front part (body). Each respirator is packaged in a separate bag.
