Kick car odors to the curb and enjoy up to 40 days of consistent scent with Febreze AUTO. While other car refreshers start off like a floral punch in the face, Febreze smells just right, right away. You'll get that first-day Febreze fresh for up to 40 days courtesy of its patented Steady Release Technology. This car air freshener vent clip is a breeze to install: Just unfold the clip until you hear a click, then clip it to your vent. It uses your car's fan to circulate an even scent through your entire vehicle. With a blend of leafy-green, floral, and watery notes, Heavy Duty Crisp Clean brings freshness into overtime with 2X the Odor-Fighting power (vs. base Febreze). These tiny car deodorizers are made with odor fighters that fight any car stink with a scent that lasts. So forget those overwhelming, fade-too-soon fresheners and enhance every drive with the long-lasting freshness of Febreze AUTO. Want a fresh that lasts at home, too?
