The present invention relates to a puff sterilization patch and, particularly, to a puff sterilization patch which is manufactured in the form of a net or fabric by using yarns made of copper having sterilizing power and can be attached to a cosmetic container so as to sterilize a puff. To this end, the present invention comprises: a pad layer formed by weaving wefts and warps into a net, wherein the wefts mainly comprise yarns made of copper and are arranged at regular intervals, and the warps mainly comprise yarns made of a synthetic resin material and are arranged at regular intervals: and an adhesive layer provided on the underside surface of the pad layer.

Provided are an inactivation method and an inactivation system designed to produce a desired inactivating effect with increased reliability using ultraviolet light that has an extremely small influence on the human body. A method for inactivating bacteria or viruses in a space defined includes a step of irradiating of an inner wall surface, a floor surface in the space or a surface of an object disposed in the space where a specified substance displaying at least one of antibacterial and antiviral characteristics is present with ultraviolet light having a wavelength within a range of 190 nm or more and less than 240 nm.

A self-disinfecting antiviral filter material 10 includes an air-permeable carrier 11 and a composite coating 12 including at least one color pigment 13 with antiviral activity and an inorganic matrix material 14 bonded to the carrier 11. The at least one color pigment 13 preferably includes at least one compound from the group of phthalocyanines. The matrix material is preferably selected from the group including metal oxides. An air filter device including the self-disinfecting antiviral filter material, a method of manufacturing the filter material, and a method of inactivating viruses are also described.

A component is provided having a component body defining at least one touch point surface. The component body includes an additive material that prevents degradation of a material of the component body in response to a cleaning agent.

An anti-microbial metal coating may be applied to filter membranes for use in actively depressing microbial viability in filtration applications. The anti-microbial metal coating may be applied to substrates that are considered to be sensitive to damage by conventional metal coating techniques or resistant to metal bonding. The coating may be applied from a salt absorbed to the substrate in solution, converted to a reducible form with a conversion agent, and reduced to active metal format through a low temperature plasma treatment.

A method for using a portable antimicrobial treatment system is provided. The method comprises: (i) providing water to a dilution reservoir, wherein a first flow controller controls a rate of flow of the water between a water supply and the dilution reservoir, (ii) providing a high ion concentrate to the dilution reservoir, wherein a dosing pump controls a flow rate of the ion concentrate between the metallic ion cartridge and the dilution reservoir; (iii) combining the water and the high ion concentrate into a diluted solution: (iv) providing the diluted solution to at least one application system, wherein a second flow controller control a rate of flow of the diluted solution between the dilution reservoir and the at least one application system; and (v) controlling, by an electronics control module, the first flow controller, the dosing pump, and the second flow controller.

In an indoor air cleaner according to the present invention, shavings 10 generated when a copper material is cut with a lathe or milling machine are stored inside a breathable net 11. The copper material may be pure copper or various copper alloys. The net 11 may be formed into a spherical shape and hung, or the net may be formed into a container and placed on a desk or the like. When airborne bacteria and viruses in a room come into contact with the surfaces of the shavings 10, the antibacterial and antiviral effects of copper can reduce the activity of the bacteria and viruses.

The present disclosure provides a toilet seat including a rim; and a tab made from an antibacterial material and configured to be attached to the rim as a touch point for a user to open or close the toilet seat. The present disclosure provides a toilet including a toilet bowl; a toilet seat comprising a rim and pivotably attached to the toilet bowl; a toilet lid pivotably attached to the toilet bowl or the toilet seat; and a first tab made from an antibacterial material and configured to be attached to the toilet seat as a first touch point for a user to open or close the toilet seat

A surface coating composition may include titanium dioxide optionally combined with copper oxide to permanently bind to any surface to create a long lasting, self-cleaning, deodorizing, and antimicrobial surface, and preparation method thereof. A method of continuous flow process to create anatase TiO.sub.2 crystals with particle sizes ranging from about 0.1 nm to about 200 nm, or further ranging from about 0.1 nm to about 20 nm in size.

A filter and a filter system including the filter. The filter includes a porous filter frame having a first upstream-side surface, and a second downstream-side surface based on a thickness direction, the porous filter frame filtering particulate matter. A copper material layer is disposed on at least a portion of the first upstream-side surface of the filter frame.
