An adjustable fan stand is presented. The fan stand has an essentially parallel-piped upper housing that would be slightly larger than the standard twenty-inch by six-inch box fan. The upper housing is supported by two legs which are also connected at the bottom by a support. The legs have perpendicular feet which allow the entire fan stand to remain in position when a box fan is placed inside the fan housing. The fan housing has a number of vertical holes and is connected to each of the legs by wingnuts. By utilizing the various sets of holes and tightening or loosening the wingnuts, the height of the box fan above the floor may be adjusted as desired. The pitch of the box fan may also be adjusted to direct the cooling air to the upper torso of a worker as desired.
