The odour eliminating mist moves through the ventilation system, across the headliner and in-between seats and all other hard to reach areas, eliminating odours and leaving a fresh,  woody, cologne frangrance. Air Refresher does not simply mask odours - it eliminates them! Note that this is a one time use product. Press the fogger activation and allow it to dispense in the closed vehicle while the ventilation system is running in recirculation mode. The vehicle must remain unoccupied during this process and for 10 minutes afterwards.
