Raw materials list: polypropylene nonwovens, meltblown filter cloth, nose clip bar, and earrings

Spunbond nonwoven prevents droplets, body fluids, etc. from entering the mouth and nose directly. The inner layer raw material of spunbond nonwoven absorbs moisture and is at the same time the last barrier between the virus and the respiratory tract.


The meltblown nonwoven in the middle has an ultra-fine fiber structure that prevents viruses, which are even finer particles, from entering. In addition to the mechanical filtration of particles, the fibers can also adsorb even smaller particles through molecular gravity and electrostatic effects.
