Abstract: A Point of Use (POU) filtration device has a hollow conduit having open ends. An Ultraviolet Light Emitting Diode (UV-LED) module is coupled to the hollow container.

Abstract: The present invention relates to a carbon-based material for use in a piece of personal protective equipment and an air filtration system. The carbon-based material may function as a filter by providing a tortuous path for a pathogen to traverse. The carbon-based material may be used as a carbon-based heater that can reach a pathogen inactivation threshold temperature to enable heat inactivation of one or more pathogens. In embodiments where a piece of personal protective equipment includes a carbon-based heater, an insulating layer may be included to attenuate the temperature generated by the carbon-based heater from the face of a user.

Abstract: Provided herein are photocatalytic carbon filters for the removal impurities such as microorganisms, organic compounds, algal toxins, and their degradation by-products from water and wastewater. The photolytic carbon filters comprise a porous titanium substrate comprising TiO2 nanotube arrays and multi-wall carbon nanotubes disposed on the TiO2 nanotube arrays. Also provided herein are methods of manufacture and methods of use of the disclosed photocatalytic carbon filters.
