Review on Car Air Purifier Ionizer - 12V Plug-in Ionic Anti-Microbial Car Deodorizer with Dual USB Charger - Eliminate Smoke, Pet Odors, Food Odors, Allergens, and Viruses in Your Car (Matte Copper) by Heather Johnson

My 10 year old son plays soccer and often drives 4 hours in the car. I needed a solution that would remove some of the odors associated with food, sweaty boots and dirty socks! I tried it. The fact that it had two USB ports was an attractive bonus (I can still keep my phone charged). How can I measure if it works? I admit it's difficult. But I no longer notice the main smells associated with the changing rooms. Actually I don't feel anything. This is the score in my world! =
