Title: a better idea
Product review: Just don't waste your money on this. As a better answer, I buy a spray can of lysol which you may already have for the bathroom and spray liberally into the ducts, including the ac return under the passenger side dash (probably). This kills the bacteria (and more) which is the cause of the odors. After spraying wait an hour then crank up the blower for the heat/ac or just fresh air and let it run while you wait a bit outside the car. You choose the flavor. Voila!
