An air purifier (100) includes a housing (400) formed with an air duct (401), an ozone generation device (20), an activated carbon purification unit (80), and a fan (200) arranged in the air duct (401). The air duct (401) includes an air inlet (402) and an air outlet (403). The air outlet (403) is disposed indoors. The ozone generation device (20) and the activated carbon purification unit (80) are arranged in the air duct (401) along the direction of the air inlet to the air outlet (403), and the ozone generation device (20) is used to generate ozone. The fan (200) is used to suck gas from the air inlet (402) during operation and let the gas pass through the ozone generation device (20) and the activated carbon purification unit (80) to be discharged from the air outlet (403) into the room.

An ozone generator voltage verification light assembly generates a visual or audible indicator, such as a neon light, to verify that an ozone generator is generating the proper voltage to generate ozone, and/or ozone generator voltage verification light assembly testing assembly operatively connects to an ozone generator, and visually indicates if an irregularity in voltage occurs. The ozone generator includes a power source for supplying electrical current, and a transformer that generates high voltage. The ozone generator also includes single or multiple ceramic plates disposed in a spaced-apart, parallel relationship, and coated with stainless steel mesh. Voltage generated by the transformer contacts the ceramic plates by means of an electrode. Accordingly, ozone is generated by discharging electricity through electrodes that contact in both sides of ceramic plate.

A fragrance dispenser and a corresponding method of dispensing fragrance, comprising at least one receptacle having a major open end, with a porous diffuser layer occlusively overlying the major open end of the receptacle, wherein at least a sectional area of the porous diffuser layer is removable to uncover a portion of the receptacle to control of the release rate of a fragrance source. The fragrance dispenser may comprise a plurality of receptacles and the porous diffuser layer comprises a plurality of sections that are individually removable to uncover each receptacle. The fragrance dispenser could comprise a removable cover sheet that is peelably detachable from the porous diffuser layer. Porous diffuser layer could be an organic polymeric nonwoven web and/or the receptacle is made of a thermoplastic organic polymeric resin. The fragrance dispenser may further comprise a secondary diffuser layer that has 50% more permeability that the porous diffuser layer.

The present deodorant-containing processing liquid includes an acid salt of an aminoguanidine, an inorganic carrier capable of carrying the acid salt of the aminoguanidine, a dispersant, and water, a content of the acid salt of the aminoguanidine is 15 parts or more by mass based on 100 parts by mass of a content of the inorganic carrier, and the dispersant is at least one selected from a group consisting of an anionic surfactant and a nonionic surfactant.

A portable device for spreading odors is disclosed. The portable device may include: a housing configured to hold: at least one replaceable cartridge holding an absorbing element absorbed with a volatile liquid; and a ventilation unit configured to provide air flow to the vicinity of the at least one absorbing element. The hosing may include: at least one insertion entrance for inserting the at least one replaceable cartridge; and at least one volatile compound exit.

A method and system are provided that include features for operating an appliance in an odor removal cycle. In one aspect, an appliance has a housing defining a sealable volume and includes an ozone generator, an ozone detection device, and a controller. In an odor removal cycle, the controller causes the ozone generator to inject, at a predetermined injection interval, predefined dosages of ozone into the sealable volume of the appliance. The controller monitors the concentration level within the sealable volume after each injection based on inputs received from the ozone detection device. The controller ascertains when the concentration level reaches a maximum concentration level threshold, and when this occurs, the controller can cease the injections and can activate one or more ozone removal devices to remove the ozone from the sealable volume to a safe level.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

A fragrance dispenser for emitting fragrance into an airstream impinging on an air filter, the dispenser having a receptacle with an open end that faces toward the air filter and that has a porous diffuser layer occlusively overlying the open end of the receptacle.

Disclosed herein are flexible plasma applicators based on fibrous layers that are capable of rapidly sanitizing a surface via either direct or indirect contact with said surface.

Chlorine dioxide gas is immediately generated at a stable concentration from a liquid composition. The composition is obtained by mixing an aqueous chlorite solution, an activator that immediately adjusts the pH of the aqueous chlorite solution, an activation inhibitor that slowly mitigates an action of the activator, and a metal iodide such that the metal iodide is contained in a proportion of 0.4% by mass or less and the activation inhibitor is contained in a proportion of 1% by mass or less with respect to 1 L of 1% by mass aqueous chlorite solution.
