摘要： The object of the present invention is to reduce the exposure of polluted air to a baby, and in particular to minimize the pollutions inhaled by a baby when strolling, walking or transporting a baby in an exterior environment. The object is attained by providing a portable device for filtering air, the device being adapted to be arranged in association with a top end of a baby-transporting device. With such an air-filtering device, air from outside of the baby-transporting device may be filtered and purified before being provided in a well-distributed manner to the area of the baby-transporting device where a baby is positioned.

摘要： An air purification system is provided which includes measurement of a concentration of a target pollutant within the air. A gas sensor is used for sensing a concentration of the pollutant (although it will detect other pollutants as well due to cross-sensitivity). A filter is provided which selectively removes the target pollutant while having a significantly smaller effect in reducing other pollutants to which the sensor is cross-sensitive. A gas sensor response is obtained before filtering, a gas sensor response after filtering, and the sensitivity characteristics of the gas sensor to the pollutant are processed, thereby to determine a gas concentration of the pollutant in the air before filtering. In this way, the concentration measurement is better than a direct measurement with the gas sensor as a result of a low selectivity of the gas sensor.

摘要： The application provides a fresh air purification window for preventing haze. A ventilation device is provided with an upper layer and a lower layer and partitioned by a transverse middle-layer partition plate, an exhaust fan is mounted in the upper layer, an air feeder is mounted in the lower layer, an air inlet grille is formed on the upper layer through front-layer glass, and a half-closed space with an air cavity unidirectionally provided with an exhaust opening is formed by the upper layer, upper-layer glass, a middle-layer separation partition plate and air cavity one-sided glass. The fresh air purification window has the effects of lowering the shielding light ray of the current purification window and enabling the current purification window to be compact in structure.

摘要： An outdoor air cleaning system includes a partition surrounding a purification space to isolate the purification space from an external space and having at least one opening connecting the purification space to the external space, an air purifying device configured to supply purified air to the purification space, and a controller configured to control the air purifying device. An openness level defined as an area ratio of the opening with respect to a surface area of the partition is about 10% or more and about 50% or less.

摘要： A road vehicle with a vehicle frame and a rear axle connected to the vehicle frame is provided with an ambient air purification device with filter elements for removing dust, particulate matter, and gases from ambient air. The ambient air purification device is arranged transverse to a longitudinal vehicle axis in an exterior region of the road vehicle at a vehicle rear of the road vehicle in an underfloor region such that at least the filter elements are arranged behind the rear axle of the road vehicle in a travel direction of the road vehicle. The ambient air purification device is received in an installation space of the vehicle frame. The ambient air purification device is flowed through in longitudinal vehicle direction. A free outflow zone of the ambient air purification device is arranged, in travel direction of the road vehicle, behind the ambient air purification device.

摘要： A vehicle including at least one filter for trapping particles in a vehicle's outside surrounding air. The filter includes a first part and a second part. The first part includes a first cilia layer. An air inlet is arranged in one end of the filter. The first cilia layer is arranged to trap at least some particles in the air flowing into the filter via the air inlet when the first cilia layer is electrostatically charged by an electromagnetic field. The filter is connected to a vehicle chassis and such that one of the first and second parts faces the vehicle chassis and the other part faces ground.

摘要： A system and method for reducing smog in an urban area includes an urban area having an urban surface. A smog atmospheric layer is located above the urban surface. A mixing atmospheric layer is located above the smog atmospheric layer. A plurality of turbines is located on the urban surface and moves a quantity of air between the smog atmospheric layer and the mixing atmospheric layer. A system and method for reducing smog in an urban area includes an urban area and a rural area adjacent to the urban area. An urban boundary demarcates the urban area and the rural area. A plurality of turbines is located within the rural area and/or the urban area, and moves a quantity of air between the urban area and the rural area.

摘要： A filter may remove PM2.5 and/or other airborne pollutants, which filter has fibers of an average diameter of no more than 500 nm, the fibers of at least 90 wt. % polyacrylonitrile, relative to all fibers in the filter; and a catalyst of at least 90 wt. % TiO2, relative to all catalytic metals in the filter, dispersed onto the fibers. The fibers need not be charged. The TiO2 may be condensed or precipitated onto the fibers out of a liquid containing the TiO2 and the fibers by simple methods. The catalyst may be activated by UV irradiation to decompose particulate matter having an average particle size of 2.5 μm or less, i.e., PM2.5, and/or other airborne pollutants from air. Such filters may be implemented around areas of vehicle traffic, e.g., as elements of traffic lights, and may be used to controllably purify polluted air.
