Title
(EN) PATHOGEN-KILLING FILTER ASSEMBLAGE
Abstract
(EN)

A filter configured for capturing and killing pathogens, the filter including a first breathable layer including copper; and a second breathable layer including silver, the second breathable layer coupled to the first breathable layer, wherein the first breathable layer and the second breathable layer cooperate to capture and kill pathogens mobilized through at least one of the first breathable layer and the second breathable layer.
