A method for cleaning medical equipment by scrubbing the equipment with an open-cell melamine-formaldehyde foam comprising an antibacterial active composition, and wherein the open-cell melamine-formaldehyde foam is prepared from a melamine-formaldehyde precondensate, wherein the molar ratio melamine to formaldehyde of the melamine-formaldehyde precondensate is smaller than 0.5.

A disinfectant fog dispensing container and system includes a cylindrical container and a transparent widow for viewing the amount of fluid in the container. The container further includes a fill port on the side of the container. The fill port provides access to an interior of the container and allows the user to fill the container with fluid therein which will then be dispensed as fog. Additionally, the system includes a battery powered rotating base wherein the container will rotate and dispense the contents of the container in an enclosed area. The enclosed area may include locations such as a living room, a classroom, or a vehicle.

A composition for disinfecting air including a biochar combined with a biocide. According to an embodiment, the biocide is mechanically active, i.e. it destroys, prevents the action of the pathogenic microorganism by mechanical action and without chemical action. Another aspect relates to a device for disinfecting air including the composition and a support. Another aspect relates to the use of the composition for disinfecting air or a disinfection device for reducing the amount of pathogenic microorganisms in an air flow. The present disclosure relates to the field of air disinfection. In an embodiment, it can be applied to the treatment of air for the purpose of suppressing pathogenic microorganisms such as viruses, bacteria, fungi. An embodiment can be applied in an air treatment device for treating enclosed spaces such as an entire structure or specific spaces in a building or any transport vehicle.

A straw structure is provided. The straw structure includes a straw body, and the straw body has a first beveled edge at an opening of a bottom end of the straw body and a second beveled edge connected to a rear side of the first beveled edge. A puncturing end opening is formed at the first beveled edge and a side edge of the straw body, and the bottom end of the straw body has a beveled opening formed at the second beveled edge. The puncturing end opening is an acute angle that is less than 90 degrees, and a slope of the second beveled edge is greater than a slope of the first beveled edge.

An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO.sub.2, ZnO, NiO, and WO.sub.3; and a light source for emitting light to the photocatalytic filter.

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.
