A disclosed embodiment provides a clothes care device which can improve service life, is not influenced by humidity, and can resolve odor problems. A clothes care device, according to one aspect of the present invention, comprises: an air blower; a flow path through which air, which is made to flow by the air blower, moves; and a deodorizing module for purifying the air which is made to flow by the air blower. The deodorizing module comprises: a ceramic filter provided inside the flow path; and an ultraviolet light emitting unit provided on the outside of the flow path so as to face the ceramic filter.

An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.

The invention relates to a reactor for purifying a gas flow by contact with a liquid. The reactor comprises a chamber which delimits a channel having an inlet opening and an outlet opening for the gas flow. The chamber has walls made of a flexible material which is secured to an inflatable structure which is provided with means for retaining pressurised air therein in order to form a self-supporting flexible structure with trapped air.

A free standing liquid membrane is disclosed that can selectively separate objects based on the kinetic energy value of the objects such that either an object having a first kinetic energy value can pass through the free standing liquid membrane while retaining the membrane and/or an object having a second kinetic energy value is prevented from passing through the membrane while retaining the membrane. Advantageously, the free standing liquid membrane can remain intact for seconds to hours with multiple objects passing through the membrane.

The present disclosure provides, in one embodiment, a filter device comprising a mouthpiece, a filter assembly in communication with the mouthpiece for filtering air exhaled into the mouthpiece, and an outlet check valve which permits air to be exhaled through the mouthpiece into the filter assembly, and substantially prohibits air from being inhaled from the filter assembly into the mouthpiece.

An air circulating trash can having antibacterial and deodorizing functions includes a trash can body having an open top and a lid coupled to the top of the trash can body to open and close the same. A filter mounting part is formed on the lid, and a functional mesh net filter having antibacterial and deodorizing functions is fixedly provided thereon so that air inside the trash can body and air outside circulate via the functional mesh net filter. During ventilation, the functional mesh net filter absorbs and decomposes the odor and bacteria inside the trash can body and the odor and bacteria outside to maximally decelerate the speed of decay of trash due to ventilation, prevent growth of various germs by antibacterial effect, decrease concentration of odor leaking to the outside by absorbing and decomposing the odor, and inhibit harmful insects such as fruit flies or cockroaches from entering.

A material for removing a contaminant, a filter for removing a contaminant including the material, and a device for removing a contaminant including the filter, the material including an adsorption material for adsorption of a contaminant and a decomposition material for decomposition of a contaminant, wherein the adsorption material and the decomposition material are complexed with each other, and a contaminant decomposition onset temperature of the decomposition material is equal to or lower than a contaminant desorption onset temperature of the adsorption material.

A device is provided. The device includes one or more of a container, filtration media, and a vacuum apparatus. The container includes a first hole in a first end of the container and a second hole in a second end of the container opposite the first end. The filtration media is disposed within the container, and is configured to absorb an odor present in inlet air. The vacuum apparatus is coupled to the first hole, and is configured to pull inlet air through the filtration media from the second hole and provide filtered air to the first hole.

A miniature gas detection and purification device is disclosed for a user to carry with himself, and includes a main body, a purification module, a gas guider and a gas detection module. The gas detection module detects gas of surrounding environment to obtain a gas detection datum, and controls the gas guider to be operated according to the gas detection datum, so that gas is inhaled into the main body and flows through the purification module for filtration and purification, and the gas purified is finally guided to a region close to the user.

To adsorb a substance to be treated in a fluid (7) with a higher adsorption capacity and lower pressure loss, an adsorptive sintered compact (20) includes powder adsorbent materials (1a, 1b), and resin structures (2) in which voids (3) are formed in a three-dimensional network. The powder adsorbent materials (1a, 1b) include free adsorbent materials (1a) free-movably contained in the voids (3) between the resin structures (2), and fixed adsorbent materials (1b) fixed to a surface (2a) of the resin structure (2) and/or at least partly embedded inside the resin structure (2), and the powder adsorbent materials (1a, 1b) are at least one of powdered activated carbon, powdered activated clay, and zeolite.
