WHERE TO USE: CAR Vent Clips work in virtually every vehicle - mom mobiles, commuter carpools, dog cars - with scents that beg for the windows to stay up. WHEN TO USE: CAR Vent Clips last for up to 30 days, eliminating tough odors that tend to hitch a ride. Too bad they can't eliminate traffic.

Depending on the type, a car air freshener can last anywhere from a few weeks up to a few years. One to two months is the most common lifespan for all types of fresheners, from vent-clips to sachets.

A four-pack of vent sticks offers four weeks of fragrance.

The Febreze Car Vent Clip doesn't release any scent. It may take a few minutes for the fragrance to be released. Check the bottom corners of the product to see if there are small holes in the foil (which indicates that the scent is being released). If there are no puncture holes, try snapping the clip into place again.

The Febreze Car Vent Clip doesn't release any scent. Make sure the clip in the back of the device has snapped into place and is at a 90 degree angle. Make sure you have set the level of scent to 'HIGH'. It may take a few minutes for the fragrance to be released.

In a closed space like a car, we prefer the airy scent from the aptly titled "Air" version. One important note: Don't leave a can of Febreze car air freshener inside the car. The contents of this spray air freshener are under pressure and high temperatures inside the vehicle can lead to unwanted mishaps.
