After a long day of driving, your car might not smell as fresh as it usually does. And taking it out again when it reminds you of muddy shoes, damp clothes, or your pet might not seem too appealing. However, using the best essential oils for car diffuser can make your car smell brand new.

Oil diffusers are easy to install into the AC vent outlets or other small spaces in your vehicle.

The oils listed here come in various fragrances, so choose one that helps you relax without overwhelming your senses.

Types Of Car Diffusers

There are three types of diffusers that can be used in cars.

  1. Plug-in: Plug-ins are popular as you can plug them into USB ports or a car’s charging socket. They emit mist at different speeds and often double as humidifiers. They usually have attractive LED lights. 
  1. Vent clips: You can fix vent clips on the exhaust port of your car. They use the heat or cold air in the car’s air conditioning system to slowly release essential oils. They contain oil-absorbing pads and have refillable bottles. They usually last longer than the plug-in variety, but they may be less effective.
  1. Rechargeable: Like plug-in devices, they can be used with rechargeable batteries and do not need to be plugged in all the time. The added benefit of these products is that you can place them anywhere in the car.
