1. A method for decontaminating an article or substantially enclosed space contaminated with a virus, comprising the steps of: shearing a cleaning fluid into a mist at substantially one atmosphere ambient pressure comprising aerosol droplets accumulating in a top chamber portion of a substantially closed chamber comprising a funnel shaped top chamber portion, a bottom chamber portion, a side chamber portion and an interior chamber portion, wherein the cleaning fluid is sheared by ultrasonic cavitation, wherein the cleaning fluid comprises a source of an active species for decontamination of an article or substantially enclosed space, wherein the active species is hydroxyl ions and wherein the source is hydrogen peroxide and the cleaning fluid is silver-free, chlorine-free and peracetic-acid free; subjecting the mist to a nonthermal plasma actuator to form plasma activated ionic particles carried by the aerosol droplets of the mist, wherein the plasma activated ionic particles are hydroxyl ions, wherein the nonthermal plasma actuator is a DC arc; dispersing the mist by high voltage actuation; and contacting the article or substantially enclosed space to the plasma activated ionic particles.
