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.

Humidifying and cleaning device of the present disclosure includes: centrifugal crushing unit that generates hypochlorous acid water micronized by a micronization operation for micronizing hypochlorous acid water stored in humidifier tank, and causes air flowing inside of the humidifying and cleaning unit to contain and release the hypochlorous acid water micronized by the micronization operation; and humidification controller that controls the micronization operation. Humidification controller is configured to perform a first treatment of draining the hypochlorous acid water stored in humidifier tank and supplying new hypochlorous acid water based on time information specified in advance during the micronization operation, that is, time information from when the micronization operation is started until a content of the hypochlorous acid contained in the hypochlorous acid water stored in humidifier tank becomes less than or equal to a reference content.

An airborne virus protection and disinfection (AIRVPD) device includes positive and negative electrodes arranged to form an electrode fluid path therebetween and a high-voltage converter configured to deliver power to the positive and negative electrodes to trigger a redox reaction. The AIRVPD device also includes a chemical disinfecting unit having a sponge material associated with at least one of the positive and negative electrodes and capable of becoming impregnated with an antimicrobial capable of killing airborne viruses. The AIRVPD device further includes a housing encasing the positive and negative electrodes, the high-voltage converter, and the chemical disinfecting unit. The housing includes an inlet and an outlet in fluid communication with each other via the electrode fluid path. Ionized air with charged droplets external to the AIRVPD device is able to flow through the AIRVPD device for disinfection and neutralization.

A plume cleaning system for a toilet is integrated with a toilet. In one example, a plume cleaner assembly adjacent to a toilet seat is independently removable with respect to the toilet seat. The plume cleaner assembly may include a plume cleaner, apertures, and a fan positioned to draw plume air through the plurality of apertures for treatment by the plume cleaner and expel the treated plume air out of the plume cleaner assembly in a direction at an angle to the apertures. In another example, a plume cleaner assembly with the toilet seat may include at least a fan, an electrostatic collector, and a mist generator. In another example, a plume cleaner assembly is integrated in a tank of the toilet to generate a sanitization fluid that is channeled into the toilet bowl through an overflow tube and/or rim channels.

To provide a method for disinfecting air and/or surfaces which can be carried out truly continuously, in particular for essentially 24 hours a day, with people and/or animals present, the a method for disinfecting air and/or surfaces is proposed, wherein a disinfectant is dispersed continuously into a volume and/or area to be disinfected, wherein the disinfectant comprises electrolyzed and/or sterilized water containing hypochlorous acid, and wherein the disinfectant is dispersed at a dispersion rate between 0.5 ml/m.sup.3/h and 12 ml/m.sup.3/h.

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.

The present invention discloses an integrated technique for sterilization or disinfection or sanitization, to remove microbial load in air or in liquid or on solid surfaces using water, gases and electrical energy. Electrical energy is used in the present invention to generate ions or electrically activated species from mixture of gases generated from electrolysis, air and water mist which can be directly used for sterilization or can be dissolved in water to create electrically activated water. This water is directly used for surface disinfection or may be converted into activated water mist for disinfection of air. The gas plasma or activated water mist may also be dissolved in water for disinfection of water.

A hand wash cleaning and environmental purification diffuser includes tank cover covered on a slot of a water tank in a bottom shell, a diffusing cover assembled to an opening of the bottom shell to shield the tank cover, an air flow channel formed in the oscillation space in the water tank and shaped like a tubular bulge so that when the diffuser is dumped, the liquid in the water tank is less likely to seep directly into the interior of the diffuser or the environment, two oscillators mounted in the oscillation space in the water tank and respectively coated with a layer of acid and alkali resistant coating, users can add safe cleaning liquids such as alkaline ionized water to the oscillation space and atomize into a cleaning mist, which can be used as deodorization and sterilization for hand cleaning, disinfection and environmental purification, and is safe to use.

A housing having an inner chamber; one or more channels within the housing; one or more inlet ports for allowing air into the one or more channels; each inlet port having a filter to filter air allowed into the one or more channels; the one or more channels connected so that the same air can flow through all of the one or more channels; a pool of electrolyzed high acidity water in the inner chamber of the housing; and wherein contaminants in air flowing through the one or more channels are configured to fall into the pool of electrolyzed water. The apparatus may further include an ultraviolet light source; wherein the ultraviolet light source is directed at air flowing in the one or more channels to cause contaminants in the air to be killed. A mask may be configured to attach and detach from the one or more channels.

A versatile sanitizing and cleaning apparatus (10) has a reservoir (30), a removable base (40) at the bottom of the reservoir having electrodes (52, 54) that extend up into the reservoir (30) for electrolyzing water within the reservoir, and an opening (32) at the top end of the reservoir. A cap (60) having a valve (61) that is biased to the normally-closed position screws to the top of the reservoir (30), allowing the reservoir to be turned upside-down and inserted into a receiving portion (22) of a mop, thus allowing the mop (12) to use electrolyzed water for cleaning. Alternatively, instead of being used with the cap (60) and mop (12), the reservoir (30) and base (40) can be mated with a hand sprayer (64) allowing the reservoir (30), base (40), and hand sprayer (64) to be used as a spray bottle (69) to spray electrolyzed water for cleaning purposes.
