Provided is an air cleaning system including: an ozone generation unit that generates ozone gas; and a discharge unit that atomizes or vaporizes an aqueous alcohol solution and discharges the aqueous alcohol solution. A mole fraction of an alcohol included in the aqueous alcohol solution with respect to the aqueous alcohol solution is 0.05 or more and 0.35 or less. A hydroxyl radical is generated through a reaction of the ozone gas with the aqueous alcohol solution that has been atomized or vaporized.

An elevator ventilation system comprising an ultraviolet source that illuminates elevator system air blown through an illumination chamber, and an air filter that filters the air as it flows through the chamber. The ultraviolet source is blocked from view from outside the illumination chamber. An air curtain emitter may expel a curtain of air across the elevator doorway, limiting air communication between an elevator interior and the elevator landing when elevator doors are open. An air outlet may be shaped to receive an elevator light fixture and to expel air into the elevator interior via an aperture adjacent the light fixture. An air curtain emitter may comprise an air outlet slot shaped to expel a curtain of air separating an interior of the elevator car into at least two air compartments defined by the “barrier” of the air curtain.

The system of the present invention is for treating surfaces and airborne particles comprising. The system includes an exterior housing and an enclosed water storage tank mounted inside the exterior housing to store water. The system may also include a dry mist generator mounted on a water float to position the dry mist generator below a surface of the water stored in the enclosed water storage tank. The system may further include an air blower having an outlet connected to water storage tank above a predetermined water level. The system may still further include an oxygen tank having an outlet, and an ozone generator connected to the outlet of the oxygen tank, The system may also include a regulator and flow meter connected to the outlet of the oxygen tank and having an inlet conduit to the ozone generator to regulate a flow of oxygen into the ozone generator.

An air disinfector and humidifier combo is revealed. The air disinfector and humidifier combo includes a tank used for storing water and provided with an air outlet, an electrolytic oxygen generator arranged at the tank for hydrolysis of water in the tank to generate ozone water, an ultrasonic oscillator disposed on the tank for atomizing the ozone water in the tank to produce ozone water mist, an air pump, a bubble refiner connected to an air vent of the air pump and mounted in the tank for generating submicron bubbles, and an electronic control unit electrically connected to the electrolytic oxygen generator, the ultrasonic oscillator, and the air pump for control of their operating time. The air disinfector and humidifier combo provides humidification, disinfection and purification functions. The submicron fine bubbles of the ozone water interact better with dirty air to improve disinfection and cleaning effect.
