Finding Your Next Car Diffuser: A Buyer’s Guide

Your car usually retains the smell of pet hair or moisture accumulated due to air conditioning, and you need a quality car diffuser to keep it smelling fresh. We’ve put together this detailed buying guide to help you pick the right car diffuser to eliminate unwanted odors.

Types of Car Diffusers

Vent clips

Vent clips are the most common types of car diffusers, and you clip them onto the exhaust vents in the car. They usually run on essential oils that dissipate slowly and keep your car smelling amazing as you use the air conditioning or heating system. Vent clips either have clips with pads that are soaked in different essential oils or devices that come with a refillable reservoir. While they usually last longer, vent clips are less effective than conventional diffusers.

Plug-in car diffuser

You can either plug these car diffusers into the power supply point or into the USB ports to diffuse essential oils in your car. Some diffusers need both water and essential oils in a set ratio, while others work solely on oils. One common thing in all plug-in diffusers is that they have different mist levels, allowing you to customize the fragrance intensity. What sets these apart from other diffusers is that they typically double as humidifiers or as light sources with built-in LEDs.

Rechargeable car diffuser

Rechargeable car diffusers are similar in design to plug-in versions and perform almost the same functions. The main difference is that you don’t need them to plug in at all times because they have rechargeable batteries, offering you more versatility and portability.

Benefits of Car Diffusers

Eliminate unpleasant odors

The most obvious benefit of having a car diffuser is to banish not-so-pleasant odors to make your car more inviting. They save you from embarrassment in front of fellow passengers, leaving your car smelling heavenly.

Aromatherapy

Many car diffusers use essential oils to keep your car free of bad odors, and some of these oils have added benefits like relieving stress and anxiety and improving the quality of life. With a car diffuser, you will kick start your day with a mood-busting therapeutic drive.

Work as humidifiers

Automatic car diffusers also work as humidifiers to improve air quality within cars. So you can breathe fresh air during dry weather without having to open the glass windows.

How To Choose a Car Diffuser?

Essential oils

Essential oils are the main source of the refreshing scent and aroma therapeutic benefits in most car diffusers, and they won’t work the same without them. If you want to save yourself from the hassles of buying essential oils separately, you should consider purchasing a diffuser that comes with essential oils to start using it right out of the box.

Diffuser mode

You should get a plug-in diffuser with different mist settings if you want to customize the ambient according to your mood and preferences. You can easily adjust and customize the amount of essential oil diffused from the device and can set it to intermittent speed to save the essential oils.

Auto shut-off

Some plug-in and rechargeable air diffusers have an auto shut-off feature to avoid dry burning when the water or oil level drops below a certain level. Turning off and unplugging the diffusers while driving can be dangerous, and you may not sometimes notice that it’s empty. If an empty diffuser keeps running for longer periods, it can also be a fire hazard.

FAQs

How long will my car diffuser last?

Plug-in and rechargeable diffusers often run out of oil and water quickly if you use them in a continuous mist setting. Vent clips, on the other hand, last longer, but you need to keep the air conditioning or heating on for them to work properly.

Should I fill water in my plug-in car diffuser?

Not all plug-in diffusers need water because some of them only work on essential oils. Some plug-in diffusers may have felt pads that soak and hold oils, so you don’t need to dilute the oil.

Which essential oils should I use for car diffusers?

It depends on your preferences and the benefits you want. If you want to have aromatherapy while driving, you should use calming oils like chamomile or lavender.
