The technology used in almost all masks for filtration is a meltblown structure that is electrostatically charged. ... The electrostatic charge is a critical feature of the mask in that it boosts the filtration efficiency (mechanical) from about 30 to 35% to over 95%.
How do you electrostatically charge a face mask?
To recharge a mask, the group sandwiched it between two metal plate electrodes, then zapped the masks with an electric field strength of 800 volts per millimeter. The field needed to be high enough to cause the polypropylene mask fabric to become conductive so charges could be deposited on it, says Levine.
Are surgical masks static?
The middle layer of a surgical mask filters pathogens, serving as a barrier to smaller particles such as germs and viruses. Static electricity within the fibers of the outer and middle layers helps block particle transmission by attracting those particles to cling to the fibers.
