Abstract: An electroceutical system integrated into an article of personal protective equipment (PPE) like a face mask. The system consists of an electrochemical cell consisting of an anodic zone capable of serving as an anode, a cathodic zone capable of serving as a cathode and, optionally, a selectively conductive switch zone electrically couplable to and separating the anodic and cathodic zones and serving to switch on and off current flow between the anodic and cathodic zones.

Abstract: A filtration article for using in personal protective equipment (“PPE”) that includes one or more layers. The article has an external side for facing side the environment and an internal side for facing the body of a user. The article is air permeable but has a porosity sufficient to entrap and thereby filter selected infectious agents (IAs).
