More than an air freshener, this small but mighty generator safely removes scents in your vehicle. Simply plug into a 12-volt power outlet, press the power button, and go. ZeroTrace™ Vehicle instantly gets to work to not just mask odors in your car, but eliminate them. Safe to use around people and pets to fight back against any unsavory smell ¬– even after a long day of hunting. How PureION™ Works This ZeroTrace™ device creates a constant flow of charged particles known as plasma ions. These electrically charged positive and negative ions naturally cling to airborne particles as air cycles through the unit. Through a bonding process, the ions render odor molecules and scent contaminants inert – all without the by-product of potentially harmful ozone.
