Best solution is negative pressure with exhaust fan + duct hoses towards the door. U have two windows so just leave the other one open only a crack while the exhaust fan is on full, then blow smoke into the intake as best you can while avoiding opening the door. Cost me around 25 for the fan and 36 for the window kit including the hose, but I bought additional hoses. If you have casement style window, you're pmuch screwed without just making a cover/adapter out of cardboard.
