1. A movable cart for decontaminating a substantially enclosed space, comprising:
a decontamination apparatus comprising:
a side chamber;
a reservoir of cleaning fluid, wherein the cleaning fluid comprises a source of an active species for decontamination of a 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;
a cavitator comprising a proximal end and a distal end, wherein the cavitator is submerged in the reservoir;
a nonthermal plasma actuator, wherein the actuator activates a mist comprising aerosol droplets generated from the reservoir at substantially one atmosphere ambient pressure;
a funnel, wherein the funnel connects the nonthermal plasma actuator to the reservoir;
an outer tube, wherein the outer tube connects the nonthermal actuator to the external atmosphere; and
wherein a mist generated from the reservoir by shearing the cleaning fluid can pass through the funnel to the actuator, and further wherein after the mist is activated by the actuator to form plasma activated ionic particles carried by the aerosol droplets of the mist, wherein the plasma activated ionic particles are hydroxyl ions, the mist is dispersed through the outer tube to the external atmosphere.
