A long drive is easier when your car smells good. A car diffuser fills the cabin with fragrance without the sticky residue of old-style air fresheners. This guide shows what to look for, using the three car diffusers we sell at The Scentry.
What to look for in a car diffuser
- Waterless and heat-free: nothing to spill in your car, and no heat near the dashboard.
- Rechargeable: a built-in battery that charges by USB, so there are no loose cables while you drive.
- Automatic on/off: a motion sensor starts the diffuser when you get in and stops it when you leave.
- Refillable: you can change the scent whenever you like.
- Adjustable intensity: useful on long trips when you want a softer scent.

Choosing a scent

Tips for everyday use
- Charge the diffuser by USB before a long trip.
- To switch to a different scent, let the diffuser run empty before adding the new oil.
- Car Pro and Car Premium have a built-in battery, so you can also use them on your desk or in a small room.
