Air Supply Apparatus
First Claim
1. An air sterilizer, comprisinga UV light source for providing UV radiation of a first intensity,a blower for generating an air stream,a particle filter for filtering particles out of the air stream, andmeans for radiating pathogens in the air stream with high intensity UV light in a high intensity zone, wherein the high intensity light is of a higher intensity than the first intensity.

Abstract
In an air sterilization system that includes a UV kill chamber for sterilizing air that is to be supplied to users, the effectiveness of killing or neutralizing pathogens is increased by including not only a UV light source of a certain intensity but also including a particle filter and providing short duration high intensity UV radiation. In the case of a user specific system that includes a face mask to supply air to a specific user, exhaled air from the face mask may be sterilized as well, either by using the same kill chamber or by using a separate kill chamber.

28. An air sterilization system for providing a sterile air supply to a face mask, comprising
a face mask having an air input and an air output, a kill chamber that includes an air flow housing having a first input for receiving air from the surrounding air, and an output connected to the air input of the face mask, a UV light source, a fan or blower for generating an air stream through the air flow housing, a particle filter for filtering incoming air from the surrounding air, wherein the system includes one or both of a TV beam magnifier and a second input to the air flow housing connected to the output from the face mask.

44. A method of reducing pathogens in an air stream comprising,
exposing the air stream to at least two different UV radiation intensities at different periods of time.
-
50. A method of providing protection against air borne pathogens, comprising
filtering the air using a particle filter, providing a loosely fitting face mask for channeling the filtered air to a user, providing a fan or blower for generating an air stream, and controlling the air pressure in the face mask to maintain substantially a constant pressure, slightly positive pressure as demand changes.
