Furthermore, the healthcare professionals pass surgical masks and N95 respirators face through a set of tests to analyze their fluid resistance, flammability, biocompatibility, and filtration efficiency.
However, the WHO advises N95 respirators to the workers who are more vulnerable to respiratory infections to high exposure with respiratory patients, respiratory secretions, splashes, fumes, sprays, viruses, and bacteria.
Furthermore, there are tons of videos available online on face masks DIY and homemade face masks. However, all these techniques make use of material that doesn’t even pass the fluid resistance test.
