An overview of the car diffuser industry

The car diffuser market is growing at an expected CAGR of 8.5% over the forecast period of 2018-2028. Currently, the Asia-Pacific region is providing the best opportunities for manufacturers when it comes to selling car diffusers. This shouldn’t come as a surprise considering the region’s growing automobile production capabilites, as well as a booming middle class that is looking for products that reflect their pursuit of a more luxurious lifestyle. 

Furthermore, the popularity of car diffusers is expected to grow due to a rise in e-commerce sales and imports, allowing consumers to find their preferred car diffusers via online stores.

The most common reasons for consumers wanting car diffusers are:

  • Promoting alertness during driving
  • Providing mental clarity when inside a car
  • Removing foul odors from the car
  • Preventing germ accumulation inside the car
  • Providing a general, pleasant scent or fragrance

The types of car diffusers consumers frequently buy

Below are three types of diffusers that consumers regularly purchase:

Plug-in diffusers

These are the most commonly used type of car diffusers and are favored by consumers for their adaptability, being easily plugged into a car’s USB charging socket. This design ranks it as a popular figure, with most of them coming with LED lights for added aesthetic appeal. Moreover, plug-in car diffusers can release mists at various speeds, thus, increasing the intensity of the fragrance inside the car.


  • Portable, allowing consumers to carry them and plug into any USB port
  • Adjustable scent diffusion
  • Easy-to-alter scents and speeds for a stronger fragrance


  • Requires a USB port to work
  • Intermittent configuration doesn’t last long during long drives
  • LED lights can be a distraction when driving

  • Can operate without a USB port
  • Most come with an auto shut-off mechanism to conserve energy
  • Quiet operation


  • May need to charge often

Vent clip diffusers

The third type of car diffuser are vent clip diffusers, which can be attached to the air-conditioner outlet inside cars. These diffusers have refillable essential oil bottles, as well as pads inside that absorb the oil. They work by utilizing the air conditioner’s hot or cool air to emit essential oils.


  • Lasts longer than plug-in diffusers
  • Have a simple working mechanism that utilizes the warm and cool air from the air conditioner outlet
  • Does not require a power outlet for it to work


  • Ccent may not be as strong as compared to other types
  • Requires more maintenance to remove the wick, clean the bottle, and stock spare bottles, etc.

How to choose the right car diffusers for consumers

Now that we’ve learned about the different types of car diffusers, it’s time to consider the other factors that matter before buying a certain type of car diffuser. These factors can vary depending on specific demographics but generally these are the major factors that should be taken into consideration:


Portability ranks as one of the most essential factors for buyers. Is the diffuser USB-friendly? Can they be carried with ease? For example, most compact diffusers come with a USB connection, making them an appealing prospect for consumers overall.


It is important to make sure that the diffusers – especially ones that come with essential oils – do not contain toxic substances that could pollute the air inside the car and put consumers in danger. Therefore, it is ideal to choose BPA-free essential oil diffusers for improved safety.

Moreover, diffusers should not affect a driver’s vision or mood when they’re driving by over-emitting scents or making them feel drowsy. Hence, sourcing diffusers with an automatic cut-off function is also crucial.

Running capacity

The diffuser’s running capacity is another important factor that appeals to consumers. When the diffusers have a larger capacity, they can emit fragrances for a longer period of time.

Nevertheless, diffusers that come with large capacities should not be so big that they can’t fit inside the car’s cup holder, for instance. Moreover, it is best that they have a limited diffusion time, especially when they’re being used in closed spaces, such as inside a car.


Another essential factor is to look for diffusers that are worth the money. These can be diffusers with a higher price but they offer better durability. This means it is a value buy for the consumers and many look for long-lasting diffusers.


A diffuser’s design should not impact their ease of use. For instance, diffusers with a top switch are easier to operate while driving.

Moreover, diffusers should come with a design that is easy to use and comfortably fits in a car’s air-conditioner vent, cup holder, or anywhere else that the consumer may want to store it.


Car diffusers should not be overlooked by wholesalers, retailers, and other businesses looking to source automotive-related parts and accessories for their target market.
The segment’s growth is backed by an increased demand and production of automobiles in general as well as consumers’ growing needs to exhibit a luxurious lifestyle by having pleasant scents, which may have the added benefit of improving driving alertness and mental clarity. If you’re looking to stock car diffusers for your business, do not hesitate to browse the massive range of products on Alibaba.com.
