Thanks sa reply. Actually I already have an ionizer nabili ko sa lazada
But dont know if it is really working, meron lang kaseng blue light. mga 2 weeks ko ma siyang ginagamit.
only thing you know if it is working if your car smells clean and fresh. its not supposed to emit a sound or something, it is designed to be there quietly.
try mo umutot sa loob ng oto... if the smell of the fart is gone in seconds, its working.....
