This sleek black car air freshener works automatically to keep your vehicle smelling fresh. When you start your car, it powers on and begins emitting a subtle fragrance. Once you reach your destination and turn off the ignition, the freshener enters sleep mode to conserve energy. Three intensity settings allow you to control the scent strength - choose a light, mild aroma or crank it up for strong air purification throughout the cabin. A gentle mist is continuously circulated for up to 30 days on a single refill. Installation is quick and hassle-free with an adjustable vent clip. Say goodbye to unpleasant odors from pets, food, or other sources with this low-maintenance automatic car freshener.
