Febreze カー用ベントクリップ リネン＆スカイ 芳香剤（4個パック）

I've had one clipped to my car's vent for three weeks now and the scent is still noticeable without being overpowering. It really does seem to neutralize cooking smells from takeout, not just cover them up.

Clipped one onto my visor a week ago and the light linen scent is subtle but definitely noticeable, way better than those overpowering tree-shaped ones. I’ve had it on low setting the whole time and it’s still going strong, so the 30-day claim seems legit so far.

Finally found something that actually clears the fast-food smell out of my car instead of just covering it up with perfume. I set the dial to low and the fresh scent lasts a solid three weeks so far.
