Best car essential-oil diffuser

Which car essential-oil diffuser is best?

If you use your car for many different activities and would like it to smell fresh and clean, consider purchasing a car essential-oil diffuser. Whether you are the designated soccer parent and often transport sweaty athletes after a big game, use your car to haul work equipment or you simply want your car to smell better, these items work to leave your car smelling clean throughout, no matter what scents are brought in. A good diffuser will be small and compact and will dispense the desired scent throughout the entire vehicle. In pursuit of the best car essential-oil diffuser consider its portability, what items are included in the price and what features it offers.

What to consider when buying an essential-oil diffuser for your car


When purchasing an essential-oil diffuser for your car consider one that is lightweight and fits in various locations. A good essential-oil car diffuser will be small, but feature maximum scent output. Items that are portable are able to be closed securely and do not feature multiple parts. Many car essential-oil diffusers are able to be plugged into the USB port of your car. This saves space and ensures that the item can be used anywhere that there is this type of port available. 


A great essential-oil diffuser for your car will come with its own scents included in the price. Some options on the market require you to purchase your own oils for diffusing, while others provide scented, refillable pads for use. Having to purchase added material to make the product work should be noted in the overall cost. For example, having to buy your own oils can get expensive. If a product is advertised for $14 but requires separate purchases, it is more expensive than it seems in the long run. When purchasing a car essential-oil diffuser, make sure that it is compatible with all different brand scents and allows for maximum scent output.  


  • Simplicity: A diffuser that is designed simply will be of best use for those on the go. Diffusers that feature one or two options for mist control, power and lighting are not complex to understand and can be operated quickly in a time crunch. 
  • Safety: A car essential-oil diffuser that is designed with safety in mind will feature an auto-shutoff option. With this feature, the device will stop when the water reaches the empty line to prevent dry burning and provide users with worry-free diffusing. 
  • Modes: A good diffuser will feature multiple options for mist settings. For example, a diffuser that allows you to set the level of mist that your item diffuses gives you more control in the process. Some diffusers feature constant and intermittent mist settings, depending on your preferences. 
  • Light: Aside from safety and simple operation, car essential oils designed with color-changing lights can serve as multi-purpose products. The color-changing lights can work to enhance your mood and serve as a nightlight when needed. Some items feature constant changing lights while others stay concentrated on one color.  

Car essential-oil diffuser price 

The best car essential-oil diffuser will cost $13-$25. The price will vary depending on the item’s features, additions and make. Diffusers with multiple options (mist, lighting and safety) will be priced $20-$25. 

Car essential-oil diffuser FAQ

Which essential oil makes me more alert when driving? 

A. For alertness and focus while driving, users should diffuse a peppermint essential oil. The peppermint works to reduce stress and allows for mental clarity when diffused. This can help users pay more attention while driving and will not cause them to be drowsy behind the wheel. 

Which essential oils should you avoid when driving? 

A. When diffusing essential oils in the car, avoid lavender and clary sage oils, among others, as these oils have been known to cause calmness and induce tiredness. Other oils that induce sleep and relaxation are ylang-ylang, cedar and rose essential oils. Look for oils that provide heightened alertness, rather than those used in common calming rituals.
