The fans on stands will do nothing but scatter the fumes about the room and contaminate whole space.... The idea of "ventilation" is to evacuate a certain area (your breathing space) and route in fresh air, that is why we use ducting to gather the contaminated air and send it outside where nature can dilute it....

Nature abhors a vacuum, so nature will cause a inrush of fresh air into space you have cleared using the ducting..... This is why it is imperative to have the fresh air come into room from behind you (in most cases) so the fresh air comes over your shoulders and around your head when it is clean and fresh.... This is done either by having your makeup air ducted to behind you or its source (open window) behind you....

Simple basics detailed here...... Much more written about ventilation on same site...
