Abstract:
1. A device for sanitizing and disinfecting a space comprising: a tank having an interior space for holding an aqueous sanitizing and disinfecting liquid, the tank having a bottom sector, an air inlet sector having an air inlet therein and an inner wall, and an exhaust sector having an exhaust outlet therein and an inner wall facing the air inlet inner wall, the exhaust sector inner wall and the air inlet sector inner wall forming a substantially V-shaped air pathway within the interior space, the V-shaped air pathway forming a notch generally central therein; a reactor vessel positioned within the bottom sector of the tank, a top edge of the reactor vessel in spaced relation to and generally proximate a notch of the V-shaped air pathway; an ultrasonic head support comprising means for supporting an ultrasonic head comprising an ultrasonically vibratable disc for generating ultrasonic energy, the ultrasonic head support positionable within and beneath a top edge of the reactor vessel; means for transferring liquid from the tank interior space to the reactor vessel to a level for substantially submerging an ultrasonic head supported therewithin, the ultrasonic head vibratable to form atomized micro-particles from the aqueous sanitizing and disinfecting liquid; means for drawing air into the air inlet across the reactor vessel and for exhausting the formed atomized micro-particles from the exhaust outlet; and a particle filter positioned in an airflow pathway within the exhaust sector; wherein the particle filter comprises a plurality of layers, the layers comprising a support frame having apertures of a first size therethrough, a first filter element positioned in surrounding relation to the support frame and having apertures of a second size therethrough, and a second filter element positioned in surrounding relation to the first filter element and having apertures of a third size therethrough, the first size greater than the second size, the second size greater than the third size.
