The Febreze Car Gel Air Freshener with Odourclear technology continuously cleans away tough lingering odours from your car, leaving a light fresh scent for up to 30 days. It comes with the Cotton Fresh fragrance that is inspired by the freshness of pure white cotton. Unlike most car fresheners that mostly mask with fragrance, it truly cleans away odours, leaving nothing but a delightful fresh scent in your car. It is a small, discreet air freshener device that simply clips to your car air vent and freshens your car even from the toughest odours, such as food, pets, smoke or trash. You can even control the intensity of the scent by adjusting the dial on the side. It is easy to use and doesn't need any battery or electricity, so you and your guests can breathe happily.
