The need to use filtering materials based on synthetic and natural fibers modified by bactericidal, antiviral, and fungicidal components in respiratory protective equipment and air-cleaning devices is demonstrated. The use of silver-containing agents, fuchsin dyes, and brilliant green as bioactive agents is proposed for modification of filtering materials made of ultrathin fibers such as Petryanov filtering cloth (PFC), materials made of polyester and polypropylene microfibers, and materials made of cotton and viscose. The characteristics of the materials were evaluated using the permeability of a test aerosol through the filtering material, the resistance to air flow, the throughput capability in an aerosol chamber with a disperse virus-containing aerosol, and determination of the antibacterial activity by a disk-diffusion method.
