Transmission of coronavirus is thought to occur through respiratory droplets that are released when people breathe, sneeze or talk. What the Visage Transparent Face Mask does is effectively filter out these particles.
Within the mask contains a layer of Water Electret Meltblown and it is this layer that does all of the work filtering out those particles. Compared to standard Meltblown the Water Electret Meltblown has higher filtration efficiency (removing more particles) and lower resistance (easier to breathe).
All of the materials utilised are polypropylene and polyethylene. These materials are all non-toxic and are industry standard.
