Filtering half masks for respiratory protection against nanoparticles-containing aerosols
Two filtering half masks with perlite-modified polypropylene and polycarbonate nonwoven layers were constructed and studied for penetration of NaCI and paraffin oil mist nanoparticles-containing aerosols. The half masks were more efficient than conventional half masks without perlite-modified nonwoven layers.
