PERK Vent Wrap is a breakthrough in vent air fresheners. It offers a design that is so discreet it is invisibly fresh! PERK Vent Wrap is the first air freshener to offer the patent-pending StediScent™ technology, which delivers consistent, high-quality fragrance. Each PERK Vent Wrap lasts about 15 days, so a 4-pack offers up to 60 days of your favorite fragrance and no one even knows it’s there! Some fresheners loose their scent quickly but these do not! It works so well in our stinky family car!
The Vent Wrap doesn’t block air flow from the vent and allows the vent to be adjusted as needed, unlike other vent air fresheners. I know you have tried others that once you move the vent they fall off. Not helpful but these stay put and works whether the vent is on or off.
