To provide a method for disinfecting air and surfaces which provides a continuous protection of people and/or animals from pathogens a given volume, in particular for essentially 24 hours a day, and which can be conducted with people and animals present, a method for disinfecting air and surfaces is proposed, wherein a disinfectant is dispersed into a volume to be disinfected, wherein the disinfectant comprises electrolyzed and/or sterilized water containing hypochlorous acid, and wherein a dispersion rate of the disinfectant is adjusted such, that a concentration of the hypochlorous acid in the volume is continuously between 0.05 mg/m.sup.3 and 10.0 mg/m.sup.3.

A portable hydrogen-containing ozone water humidifier including a housing with a mist outlet, a water tank for storing water, a hydrogen-containing ozone water generator, an ultrasonic atomizer for converting water into mist, a rechargeable battery and an electronic controller is revealed. An outlet pipe is connected to the bottom of the water tank and the hydrogen-containing ozone water generator is disposed on the outlet pipe for hydrolysis of the water to generate oxygen and ozone gas at an anode plate and hydrogen gas at a cathode plate and further get disinfectant water formed by ozone water mixed with hydrogen-rich water while the ultrasonic atomizer is arranged at an outlet end of the outlet pipe. The rechargeable battery provides power to the electronic controller, the hydrogen-containing ozone water generator, and the ultrasonic atomizer for driving them to work. The humidifier is compact and easy to carry.

An electron generation means for generating electrons includes a rectifier circuit and a booster circuit. AC power from a power supply is passed through the rectifier circuit in advance and then flown to the booster circuit. The rectifier circuit, according to the plus/minus inversion cycle of the said AC power, blocks current flowing toward a second terminal in a state where a first terminal of the rectifier circuit has a positive potential, and current flows from the second terminal only in the state where the first terminal of the rectifier circuit has a negative potential, and thus current flows only in one direction of the alternating current. The booster circuit boosts the voltage on a primary side, and electrons are generated from one terminal on a secondary side of the booster circuit only in a state where the first terminal of the rectifier circuit has a negative potential.

A disinfecting device is easy to use and can be easily mounted or removably connected in a dental operatory or other similar environment. The device can include a removable solution chamber attached to a base unit. The solution chamber can be a refillable chamber or a disposable chamber. The base unit can receive pressurized air, typically from a standard connection present in the dental operatory, or a dental chair, or the like. The pressurized air can be used to deliver a mist or an electrostatic fog of the solution in the solution chamber out of a nozzle. The solution bottle can be directly attached to the nozzle/sprayer device, with an air hose extending therefrom. In use, the user can turn on the system and use an activation/deactivation mechanism to deliver the atomized mist or fog to all surfaces in the room.

The invention describes a portable apparatus to treat surfaces and the air with hydroxyl ions to reduce the viability and/or kill pathogens.

Various embodiments of the present invention relate to, among other things, systems for generating engineered water nanostructures (EWNS) comprising reactive oxygen species (ROS) and methods for inactivating at least one of viruses, bacteria, bacterial spores, and fungi in or on a wound of a subject in need thereof or on produce by applying EWNS to the wound or to the produce.

An energy-independent water-based pure air cleaning system using a water electrolytic-fuel cell is disclosed. The energy-independent water-based pure air cleaning system using a water electrolytic-fuel cell proposed by the present invention comprises: a water electrolysis unit that generates hydrogen and oxygen through a water electrolysis treatment using supplied water, and supplies hydrogen gas to an energy generating unit by adjusting the pressure of the generated hydrogen gas; the energy generating unit that generates electrical energy on the basis of the hydrogen gas supplied for use as a power source for air purification; an energy storage unit that does not need energy charging and supplies the generated electrical energy as power for air purification; an oxygen exhaust port for discharging the oxygen generated in the water electrolysis unit for air purification; and a humidifier that generates water vapor by spraying or evaporating the supplied water by any one of ultrasonic vibration, heating, natural evaporation, or nozzles to control the humidity in a room.

An Air-Water-Food-Fabric-Space-Utility sanitizer (all in one) comprises a detachable blower chamber, a detachable UVC lamp holder, a detachable UVC lamp chamber, a detachable water chamber and a detachable lid. Said invention transforms to an air purifier, a chamber-style sanitizer, or a stand-style sanitizer when one or more chambers are detached. Germicidal lamps surround a target such as air, water, food (meats, plants), fabric (masks, towels), space, utility and soil to kill pests, parasites, insects and pathogenic spores. Said invention also develops seed germination. Water converts gas (MVOC) to liquid and arrests airborne contaminants. A blower drives them to water to enable the use of optimal dosage of UVC light. By either UVC-irradiating water or oxidizing water, pathogens are destroyed in the water chamber. Filters activate spore dispersal when disposed by burning. By not using potentially hazardous waste or an air outlet, pathogenic spores cannot reproduce or return to the environment.

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.
