HIGH QUALITY masks have 160 mmHg fluid resistance, greater than 98% BFE (Bacterial Filtration Efficiency), and greater than 98% PFE (Particle Filtration Efficiency) at 0.1 micron. Tested to ASTM Level 3 at Nelson Labs.
SUPERIOR PROTECTION. These protective face masks are made from high quality non-woven fabric which has increased filtration of fluids in air compared to woven cloth. 3 layers of protection helps filter microbes from entering and exiting mask while maintaining smooth breathability.
