Product Description:
Your vehicle is a haven for airborne contaminants, exhuast fumes, cigarette smoke and bacteria. The Air Purifier and Ionizer bombards your vehicle's interior with negatively-charged ions. These negative ions attract pollutants such as pollen, dust, cigarette smoke and even vaporized substances such as exhaust fumes. This effect makes the negative ions grow in size and fall to the ground; taking the pollutants out of your way, removing odors and leaving your vehicle interior smelling fresh and clean. To use, simply plug into your cigarette lighter socket - and enjoy a fresher environment. A faint light at the end of the ionizer is your assurance that your ionizer is functioning. Quiet Operation - 12 volts

I have had this car ionizer plugged in for the past 3 weeks straight and I did notice a significant decrease of doggie odor. The instructions on how it works were pretty unclear but I guess it works because people can't tell I have a dog when they get in my car. lol.
