The blower unit is designed to combat heat, pollutants and possibly pathogenic air, depending on the filter added. A portable air conditioning fan prototype was originally created to refresh cosplay or furry costumes. It can also accommodate a paper filter to serve as a biohazard filter; in this case, a hole must be drilled to let the electrical power wire pass. Place a standard computer fan (9 x 9 cm, 12 Volts, thickness varying from 2 to 4 cm) inside the case. The device can be fixed by straps passing through holes in the base. A 12V direct current supply (batteries, battery or mains transformer) must be connected to the fan. An adapter must be modeled and printed if a pipe is to be attached; alternatively, Ducktape can be used. An improved version of this device is currently being designed.
