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 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 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.
