1. RoyAroma Locket
If you love essential oils, this RoyAroma locket is a great choice. This car essential oil diffuser features a small interior pad, which you can soak with your favorite oil. Then, you insert it into the vents of your car. As the air flows out of the vent, it disperses the scent. This set comes with two lockets and 12 different pads, so you can change up the fragrance as often as you like. The locket itself is made from stainless steel and decorated with a cutout tree for a classic look.
2. MOSO NATURAL Air Purifying Bag
Prefer an unscented environment in your car? This Moso Natural air freshener helps absorb bad smells, all without putting other scents into the air. It’s a charcoal car odor absorber, so it’s non-toxic and safe to use. The highly absorbent charcoal absorbs moisture as well as odors, making it a great way to reduce mold and mildew during damp seasons. Simply place it in your center console, tuck it into a door, or hang it from your mirror.
3. USB Car Diffuser
This car diffuser plugs into your accessory port or cigarette lighter; then, it uses the power from the outlet to run a tiny diffuser.

On the side of the diffuser, there’s a USB port that you can use to charge your smartphone. This unit is small and streamlined, so it doesn’t look out of place or take up much space.
4. HEPA Filter Car Ionizer
If you’re dealing with smoke smells or odors left behind from pets, you need serious deodorizing.

To use the ionizer, all you need is an accessory port or cigarette lighter. It attacks the root cause of unpleasant odors instead of masking them. Two USB ports allow easy charging.
