Abstract
The disclosed anti-contagion facemask embodiments are a family of transparent facemasks that do not obstruct visibility of a person's mouth when worn. One problem with a typical, widely used, facemask is the difficulty in understanding a person speaking when they are wearing the typical facemask. Not only does the listener have to contend with the muffled speech of a person talking through a facemask, communication is made worse by covering up, or otherwise hiding the wearer's mouth and face with opaque filter material. Accordingly, some embodiments described herein present a clear/see-through filtration mask embodiment that does not visibly obstruct a person's mouth by providing a filtration system along or near the periphery of the facemask.
