An indoor pollution prevention system includes a plurality of gas detection modules, one or more intelligent control-driving processing devices, one or more gas-exchange processing devices, and one or more indoor cleaning and filtration devices. The gas-exchange processing device includes one or more flow-guiding component and a cleaning and filtration assembly. The intelligent control-driving processing device controls the operation of the indoor cleaning and filtration device in real-time under a surveillance condition, therefore the air pollution source in the indoor space passes through the indoor cleaning and filtration device, allowing the air pollution source in the indoor space to be filtered and exchanged to become a clean air.

An apparatus for collecting a gaseous pollutant from air may comprise multiple vertical panel-beds each containing a solid sorbent; a fan to pass the air through the multiple vertical panel-beds and over the solid sorbent; an outlet gate configured to release the solid sorbent from the multiple vertical panel-beds after the fan passes the air over the solid sorbent; a regeneration vessel configured to regenerate the released solid sorbent by recovering the gaseous pollutant from the released solid sorbent; and a conveyor configured to return the regenerated solid sorbent to the multiple vertical panel-beds.

A modular air treatment unit for an over the road vehicle is independent of an associated climate control system. The air treatment unit is configured to filter and sanitize air within the passenger compartment as air moves along a flow path separate from a flow path through the climate control system. The modular air treatment unit includes a housing defining a circuitous passageway, an air filter mounted to the housing, a fan configured to move air along passageway, and an ultraviolet light source arranged in the housing. The ultraviolet light source is configured to discharge germicidal ultraviolet light inside the housing to eliminate pathogens in the housing.

A filter unit for an air cleaning device includes an odor filter configured for odor neutralization and embodied as a device for plasma generation. The odor filter includes an air-permeable high-voltage electrode and an air-permeable counter electrode arranged behind one another in a direction of flow of air. Each of the air-permeable high-voltage electrode and the air-permeable counter electrode is formed by a panel element.

An electrostatic filter unit for an air cleaning device includes an ionization unit configured to ionize particles in air and to deplete odor, and a separation unit arranged downstream of the ionization unit in a direction of flow of air and configured to separate particles.

A system including tubing and a filter configured to be fluidly coupled to a vacuum source and to a heater/cooler unit by the tubing. The filter includes a filter container having negative air pressure in the filter container provided by the vacuum source to pull aerosol from the heater/cooler unit into the filter container and eliminate and/or reduce the aerosol emitted from the heater/cooler unit.

A clothes dryer using an LED light source is proposed. Instead of using a heater, a blowing fan, and a heat exchanger, the clothes dryer employs a plurality of LED light source modules provided in a body and efficiently arranged therein and an air circulation structure of an air circulation part having a blowing fan arranged in the inner rear side thereof, and is configured to sterilize air through an air sterilization part, absorb and dry moisture by a ceramic filter, and then finally discharge the air to the outside through an exhaust fan. Therefore, without requiring a separate water discharge treatment process in an existing method, the clothes dryer can achieve efficient drying of clothes and drying of clothes without damage.

The present invention relates to a sheet filter material, in particular having an aerosol filter function and/or a particle filter function, preferably having a protective function against chemical, biological and/or chemical harmful and toxic substances, and to a method for the production thereof. The sheet filter material is particularly suitable for producing protective equipment, protective objects, sports and leisure clothing and filters and filter materials of all types.

Various embodiments of the present invention disclosed herein relate to an air cleaner, and may suck outside air and purify and sterilize the outside air, and may perform sterilization of a filter. An embodiment of the invention disclosed herein discloses an air cleaner including a body forming an appearance; a suction unit formed on the body and introduced with outside air; a discharge unit formed on the body and discharging the air introduced through the suction unit; a fan module provided inside the body and forming a flow of air introduced into the suction unit and discharged to the discharge unit; a filter unit provided inside the body to filter the air introduced into the suction unit; and a light source unit provided inside the body and irradiating light toward an inner side surface of the filter unit.
