Introducing Bio-Fresh: Air Freshener Bars, the discreet and long-lasting solution to keep your car smelling fresh for months! Our car air fresheners are the best on the market because they work and they last much longer than trees hanging on your mirror or sprays that only last a few days. Our air freshener bars can be placed under the seat of a car, truck, SUV, semi-truck, limo, or even a bus and will not be an eye sore or a distraction by dangling on your rearview mirror or blocking the air flow of your vents. Each one of our car air freshener bars comes with two uses and is a great finishing touch for any detail or car service
