Abstract: A portable air sterilization apparatus includes a portable chamber forming an interior volume, a portable source for producing a single beam of collimated light energy, and a rotating beam redirector. The portable chamber includes a first end for introducing air into the chamber, a second end for permitting air to exit from the chamber, a transparent orifice through which a single beam of collimated light energy can be introduced into the interior volume of the chamber; and at least one reflective wall. The rotating beam redirector is adapted to rotate through a complete revolution about a rotational axis and to redirect the single beam of collimated light energy within the chamber during said revolution.

Abstract: An air purification system that uses laser beams to purify air. A laser beam is set to sweep across the interior of a box that is open at two ends to the flow of air. The laser beam is of sufficient strength to destroy or neutralize any dust particles, pollen, pathogens, allergens, or gasses that are present in the flow of air through the box. An air baffle box is utilized at each end of the box with the air flow to prevent the laser beam from escaping from the box. A second preferred embodiment of the present invention is the use of a fan laser beam to purify a flow of air. Said fan laser beam is suppled to a box through which air is flowing in such a manner that all air passing through the box must also pass through said fan laser beam. An air baffle box is utilized at each end of the box to prevent the escape of laser beams.
