The four-layer respirator mask made of SPUNBOND material with a double filter is designed to protect the respiratory system from dust, microbes, allergens, and other harmful particles in the air. It consists of four layers: two layers of SPUNBOND material that provide strength and breathability, and two layers of filtering material that effectively trap fine particles. This mask provides a high level of protection and comfortable wear, thanks to its lightness and good ventilation. It is used in medical institutions, laboratories, construction, and other fields where protection from polluted air is required.
