An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

A method for screening an antimicrobial agent which is capable of controlling microorganisms causing offensive odor in an air-conditioning system and a method for removing offensive odor in an air-conditioning system are provided. The method for screening an antimicrobial agent and the method for removing offensive odor in an air-conditioning system may be used for various purposes of industrial application. For example, they may be used to develop a novel antimicrobial agent capable of inhibiting the growth of the microorganisms or to develop an air freshener for removing offensive odor by elucidating the chemical properties of the metabolites of the microorganisms. In addition, they may be used to fundamentally remove the cause of offensive odor by providing an air-conditioning system with an environment where the microorganisms may not live.

A pathogen-deactivating fibrous material is coated with salt crystals or salt crystal layer. The salt crystals or coating on the supporting fibrous material layer dissolves upon exposure to pathogenic aerosols and recrystallizes during evaporation of water from the pathogenic aerosols. Recrystallization of the salt deactivates pathogens. The pathogen-deactivating fibrous material can be used in a sanitizing fabric, an air filtering device, such as respiratory devices, masks, furnace filter devices, air conditioning device, vehicle cabin filter device, etc., and can provide a universal personal protection for preventing infections.

At least one embodiment relates to an air purifying machine comprising at least one housing and a plurality of cores wherein each core is disposed in the housing. There is also at least one fan disposed in the housing. In addition, there is at least one pump disposed in the housing, wherein the pump is configured to circulate a fluid inside of the housing. The cores comprise at least two cores disposed inside of the housing comprising a first core and a second core, wherein the second core is disposed inside of said first core and wherein the second core is not concentric with the first core. The non-concentric nature of the cores creates a compression location at a point where the two cores are disposed closest to each other. This compression location creates a higher-pressure location for air flow around the cores. The different size of the openings for air to circulate between the cores creates air turbulence which results in greater interaction between the incoming air and the bioreactive fluid solution inside of the air purification system.

An aroma diffuser includes a housing, a burner, a thermal conducting device and a hollow annular fragrance capsule. The burner and the thermal conducting device are combined in the housing. The thermal radiation of the thermal conducting device can be continuously and effectively transmitted to the donut-shaped fragrance capsule and the fragrance substance to quickly produce a stable aroma. The fragrance capsule is provided with a breathable film that prevents the fragrance substance from flowing to the outside of the fragrance capsule to contaminate the burner or the surroundings. The breathable film is formed of a fixing film and a microporous film. The fixing film combined with the microporous film is not deformed or ugly when heated, and the aroma can be diffused outward from the breathable film. The fragrance substance can be quickly replaced with another fragrance capsule after use.

The present disclosure provides compositions and methods for using the compositions to treat animal facilities. In particular, the composition comprises a metal sulfate, an inorganic acid having a pKa of less than 1, and one or more organic acids.

The present invention relates to the field of air cleaning, and specifically discloses an air freshener composition. The air freshener composition comprises component A and component B, wherein a weight ratio of the component A to the component B is 1:0.5-3; the component A comprises, in parts by weight, 10-30 parts by weight of an active agent; 6-15 parts by weight of a carrier; 1-4 parts by weight of a pH regulator; and 0.01-0.2 part by weight of an antioxidant; the component B is a plant extract solution, wherein the plant extract solution comprises at least, in parts by weight: 5-30 parts by weight of an extract of a mixture of Populus nigra var. italica, grapefruit peels and eucalyptus leaves; 0.1-5 parts by weight of Sophora flavescens extract; 1-3 parts by weight of Aloe vera extract; 1-10 parts by weight of fresh orange peel extract; 0.5-3 parts by weight of Nandina domestica extract; 0.5-10 parts by weight of Eucalyptus robusta Smith extract; 1-8 parts by weight of Robinia pseudoacacia L. extract; 1-5 parts by weight of Chrysanthemum morifolium extract; and 0.1-2 parts by weight of artemisinin.

An air purification system including a filter assembly including a substrate including a fibrous media, and a photocatalytic material disposed on the substrate, wherein the photocatalytic material includes a first quantity of crushed nanostructures; and a photon source arranged to illuminate the photocatalytic material with optical radiation.

An absorbent article comprising a complexed or encapsulated malodor control composition having at least one volatile aldehyde and an acid catalyst, and methods of use thereof, are provided. The malodor control composition is suitable for a variety of absorbent articles, including use in diapers, toddler training pants, adult incontinence garments, sanitary napkins, pantiliners, interlabial devices, hemorrhoid pads, and the like.

A water-based fragrance composition comprises at least about 67 wt % water and between about 5 and about 17 wt % of a first organic solvent, wherein the first organic solvent comprises one or more relatively volatile, water soluble, low molecular weight organic compound(s) having a boiling point less than about 100 C. The water-based fragrance composition further comprises about 5 wt % or less of at least one fragrance formulation and between about 0 and about 22 wt % of a second organic solvent, wherein the second organic solvent comprises one or more moderately volatile, water soluble organic compound(s) having a boiling point greater than or equal to about 100 C. and less than or equal to about 300 C.
