Abstract

A method and apparatus for sterilizing organic or inorganic matter through simultaneous exposure to ultrasonic wave energy (12) and ultraviolet light energy (14) in a non-aqueous environment such as air. The method is suitable for use in a chamber (60, 84) or in a mass production assembly line setting. Purification of air is similarly accomplished using simultaneous exposure to ultraviolet light and ultrasonic energy waves.
