Febreze Car Air Freshener with Odourclear technology continuously fights tough lingering odours from your Car, leaving a light fresh scent up to 30 days. The Cotton Fresh fragrance is inspired by the freshness of pure white cotton. Unlike most car fresheners that mostly mask with fragrance, Febreze Car Freshener truly fights 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 thanks to its new and unique Odourclear technology it fights odours 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.
