Abstract
A facemask structure for inactivating pathogens includes a facial contact layer that is benign to human skin followed by a subsequent interior layer and an outer layer including an anti-pathogenic material. In this manner, active, isolated anti-pathogen layers can be provided in a multilayer mask structure. For example, an important anti-viral mask structure uses one or a mixture of acids to create a low pH environment on the first inner (or outer hydrophilic layer) so that the virus laden droplets from, e.g., a sneeze, are absorbed into and away from the surface. Thus, for an infected wearer, two or more hydrophilic layers on the interior of the mask can protect the environment from an infected wearer.
