An air ioniser (or negative ion generator or "Chizhevsky's chandelier") is a device that uses high voltage to ionise (electrically charge) air molecules.

Doing some research and found this https://youtu.be/xHNZ78bttRE

The seller states that uses high voltage from the firing ignition lead to ionize air somewhat. Although this surely looks bull**** scam the theory might actually work in a similar situation?
