Abstract
An apparatus and method to actively purify and sanitize air. A flow of air is directed over a surface that includes a photosensitizer formulation which is activated by light to emit singlet oxygen that inactivates and/or kills pathogens in the air flow. A fan device is employed to generate and direct the flow of air. The fan device includes the photosensitizer formulation disposed on fan blades, rotatable fan shafts, and interior surfaces of a housing. The flow of air is emitted towards an exterior surface. Activation of the photosensitizer by light emits singlet oxygen in the flow of air to inactivate pathogens disposed on the interior surface of the housing and the exterior surface.
Claims14
A device, comprising:
- one or more fan blades;
- a rotatable fan shaft;
- an eye glass shaped frame that includes a hollow cavity and having an opening arranged to eject a flow of air towards one or more of a mouth or a nose of a user when the frame is worn on their face, wherein the rotatable shaft and one or more fan blades are integrated within the hollow cavity;
- a photosensitizer formulation that is disposed on one or more of the one or more fan blades, the rotatable fan shaft, and an interior surface of the hollow cavity of the frame, wherein the photosensitizer formulation comprises one or more organic photosensitizers;
- a container that is configured as a reservoir for the photosensitizer formulation, wherein the container is arranged to elute the photosensitizer formulation into the hollow cavity over time to maintain an amount of the photosensitizer formulation disposed on the one or more of the fan blade, the rotatable fan shaft, and the interior surface of the hollow cavity;
- and
- wherein the device generates the flow of ejected air towards an exterior surface of the user's face that includes the mouth and nose, and wherein the one or more organic photosensitizers of the photosensitizer formulation are activated by light to emit singlet oxygen into the flow of air to inactivate airborne pathogens that mix with the flow of air, and wherein the emission of singlet oxygen also inactivates pathogens that are in contact with one or more portions of the exterior surface, the one or more fan blades, the rotatable fan shaft, and the interior surface of the hollow cavity of the frame.
