摘要： Disclosed is a field-tailored prefabricated dust suction mat that absorbs and removes dust from the soles of visitor's shoes. A dust suction mat according to the present disclosure includes unit mats continuously connected to each other in a first direction, wherein each of the unit mats has a plurality of through holes for dust suction and through hole opening/closing means for opening or closing the through holes, the unit mats have lengths in a second direction perpendicular to the first direction, which are equal to each other, and widths in the first direction, which are equal to or different from each other, and an overall width of the dust suction mat in the first direction is adjusted according to the number of the unit mats, which are continuously connected to each other in the first direction. According to the present disclosure, dust suction mats can be custom-made on site in various sizes, depending on site conditions such as surrounding environment or spatial situation of an installation site, or consumers' requirements, and even when dust suction mats are manufactured in the form of ready-made products in a factory, it is possible to quickly respond to site conditions or customers' demands for size change without extensive equipment replacement or change.
