Maximum blocking size less than 0.3 micron. Due to presence of hydrophobic polyester thin film, the mask is washable with detergent for the reuse. Abundant air permeability across nonwoven barrier (0.7 cc/cm2s) ensures good breathability. Optimized loading of polymer with antimicrobial properties is expected to render antimicrobial activity on the outer surface of the main barrier.
