Abstract: An air purification system that uses laser beams (40) to purify air. A laser beam (42) is set to sweep across the interior of a box (20) that is open at two ends to the flow of air. The laser beam (42) is of sufficient strength to destroy or neutralize any dust particles, pollen, pathogens, allergens, aor gasses that are present in the flow of air through the box (20). An air baffle box (80) is utilized at each end of the box with the air flow to prevent the laser beam from escaping from the box.
