Febreze カー用ベントクリップ リネン＆スカイ エアフレッシュナー（8個入り）

Finally, a car freshener that actually eliminates sour smells instead of just covering them up. I clipped one on low setting and the gentle linen scent lasted well over two weeks in my daily driver. Eight in the pack means I can refresh all my family's cars at once.

I was skeptical about how well a vent clip could work, but this one actually makes my car smell fresh even after my dog's been riding shotgun. The OdorClear technology seems legit, and the light linen scent lasts a solid two weeks on low before fading.

These little clips have completely solved the musty smell that kept coming back in my car between washes. I love that I can just adjust the vent to control how strong the scent is, and it lasts a solid couple of weeks on the low setting.
