1. A sanitizing cabinet system comprising:
a cabinet defining a sanitizing compartment;
ozone distribution passaging in open fluid communication with the sanitizing compartment;
an ozone generator in the ozone distribution passaging;
a sanitizing air mover in the ozone distribution passaging configured to move air from the sanitizing compartment across the ozone generator to form ozonated air and to move the ozonated air into the sanitizing compartment; and
an ozone conversion device configured to be selectively opened and closed, the ozone conversion device being configured to neutralize ozone in the sanitizing compartment when opened;
wherein the cabinet comprises an upper portion generally above the sanitizing compartment, a lower portion generally below the sanitizing compartment, and a height extending from the upper portion to the lower portion;
wherein the ozone generator is received the upper portion and the ozone conversion device is received in the lower portion;
wherein the ozone distribution passaging comprises an air mover plenum in which the sanitizing air mover is received, the air mover plenum defining a return air inlet, the air mover plenum extending along the upper portion;
wherein the cabinet comprises a front and a back, the ozone distribution passaging comprising an ozone discharge plenum extending heightwise along the back from the upper portion, the ozone discharge plenum including a front plenum wall, the front plenum wall defining a plurality of orifices spaced apart along the height of the cabinet, the sanitizing cabinet system configured to discharge ozonated air from the ozone discharge plenum directly through the orifices into open space of the sanitizing compartment;
wherein the lower portion of the cabinet is an ozone conversion portion and wherein the cabinet comprises a dividing wall between the sanitizing compartment and the ozone conversion portion, the ozone conversion device being attached to the dividing wall and received in the ozone conversion portion;
wherein the dividing wall comprises an inlet opening and an outlet opening, each of the inlet opening and the outlet opening providing fluid communication between the sanitizing compartment and the ozone conversion device; and
wherein the ozone conversion device comprises:
a housing defining an interior space;
first and second dampers in the housing, the first and second dampers being configured to divide the interior space of the housing between an upstream chamber, an ozone conversion chamber, and a downstream chamber, the first and second dampers being configured to be selectively opened and closed, the first and second dampers being configured to fluidly separate the ozone conversion chamber from the upstream chamber and the downstream chamber when closed and configured to provide fluid communication between the ozone conversion chamber and the upstream chamber and the downstream chamber when opened;
ozone conversion catalyst in the ozone conversion chamber; and
an ozone conversion device air mover in the housing,
the housing being mounted on the dividing wall of the cabinet such that the upstream chamber fluidly communicates with the inlet opening and the downstream chamber fluidly communicates with the outlet opening.
