Choosing the Best Essential Oil Diffuser for Cars

Here are some of the main things to focus on while buying an essential oils diffuser for your car:

Diffuser Type
Best ones are either nebulic or ultrasonic. Nebulic diffusers are also known as atomizer style diffusers since they release the oil directly into the air without diluting it with water. They basically split the oil into nano particles and release them into the cabin of your car. Ultrasonic diffusers mix water and oil together to create a mist, thus these have a slight humidifier effect built-in. They then evaporate the mist into the air with the help of a membrane vibrating at ultrasonic frequencies.

Tank Capacity
This will decide how long your humidifier can run before you need to refill it with water. A transparent tank allows you to monitor water levels, and LED indicators will inform you about the tank status so you can refill the tank on time. If you run your humidifier on dry mode, it might damage itself and the lifespan will be greatly decreased as a result. Nebulic diffusers do not need water however, and are attached directly to the essential oil tank.

Build Quality
Take a look at the quality of the materials used in the body. Is it plastic? Or is it aromatic wood? Some oil diffusers are also made from fiberglass and feature metallic bases, etc. Choose one that feels and looks solid, so that you can always rely on it to perform at maximum efficiency throughout its entire lifespan.

Lighting Effects
Many modern oil diffusers come with built in lighting effects in order to create a much more satisfying and soothing atmosphere that compliments the aromatic mist released by the machine. Choose one with at least 5 to 7 different lighting modes (breathing, pulsating, static, etc.).

Choose the diffuser based on the above points, and get something that will comfortably fit into the car. It may go into the cup holder or a dedicated holder for diffusers, and the USB cable must be compatible with the port in your car. Also, the cord must be long enough to comfortably stretch across the dash to the ports.

If your diffuser happens to have a built-in battery, you must pay attention to the battery life rating before buying the product. Also, try to get a diffuser with automatic shut-off and optimized timer settings so that it will shut itself off if no liquids are detected inside the tank.

The timer is a great feature to have, if you want to control the amount of aroma or oils inside your car cabin. A mist control is also appreciated, since it will let you control the amount of moisture flow that is coming out of the diffuser. Too much moisture can cause issues, while too little moisture will leave you with dry skin and irritation in the eyes.
