These masks are produced by three layers which the second layer are consist of polymeric nanofiber. The scale of nanofibers are under 100 nm and they can filter dust with the size of under 2.5 µ, atmospheric particles upper than 3 nm approximately 96 percent, viruses and bacteria completely.
To improve compliance with respiratory source control via face mask and therefore reduce receiver exposure, a mask should be comfortable and effective. Breathability and filtration using nanofiber filtration have been improved. Substituting nanofiber for conventional filter media significantly reduced face mask airflow resistance directing more airflow through the face mask resulting in enhanced filtration. Respiratory source control efficacy similar to that achieved through the use of an N95 respirator worn by the source and decreased airflow resistance using nanofiber masks may improve compliance and reduce receiver exposure.
The nanofibers can improve the amount of particles filtration and also pressure drop.
