The invention relates to a household article, in particular to a window screening with adjustable air permeability. The window screening comprises an outer frame, a warp thread adjusting device, weft thread adjusting devices, drive devices and a control device. The outer frame is square, an opening is formed in the middle of the outer frame, and the opening is used for dividing the window screening to obtain the effective range; the weft thread adjusting devices are arranged on the left and right sides of the interior of the outer frame; warp threads are connected with the two side faces of the interior of the outer frame; the drive devices are arranged on the side faces of the weft thread adjusting devices; and the control device is arranged in the outer frame. The drive devices comprise drive motors, driving gears and driven gears; the driving motors are connected with the control device through wires; the driving gears are arranged on output shafts of the drive motors; and the driven gears are engaged with the driving gears. According to the window screening with adjustable air permeability, the window screening can be adjusted to be with a suitable bore diameter according to the weather demand by a user, so that air ventilation and the lighting performance are changed.
