But each also had its shortcomings.
Dr. Kumar explained that N95 respirator masks are not simply mechanical filters; some of the internal fibres have an electrostatic charge to trap pathogens. He suggests it is possible that the ionization of this type of hydrogen peroxide treatment may cause damage to the masks.
