The diffuser emits a gentle smell that is strongest for those next to the air vent where you’ve plugged in the diffuser.

If you’d like something a bit more potent - and for the scent to be more evenly distributed throughout the car - we recommend using multiple diffusers. This gives a stronger scent, allows you to mix and match different fragrances and adds a nice visual touch (our diffusers are stylish design pieces in their own right).

Typically, we expect the car fragrance refills to last up to two months. We use more natural and safer fragrance ingredients. Due to the nature of these materials, the scent typically does not last for several months—long-lasting fragrance usually correlates with higher levels of synthetic additives. Just like personal perfumes, even a single spray rarely lasts beyond a day.

To ensure a consistent scent in your car, we recommend replacing the scent refill each month.

Diffusion works best when air is flowing. The fragrance is dispersed through rapid air circulation—making it more noticeable with strong airflow. In cooler air, the scent may feel lighter, while warm air enhances diffusion and intensifies the aroma. This is a natural result of the physical properties of fragrance oils, which evaporate more readily when heated.

This really comes down to personal preference, which is why we’ve created a variety of fragrances to suit a wide range of olfactory palates. Some people like to pick one scent and stick to it, while others prefer to mix and match in the car. We encourage to be playful with multiple diffusers and our moving scent refills to create a unique olfactory environment in your car.

The diffusers have flexible clips which attach easily to the air vents inside your car. They work with a twist-lock mechanism, so you can fill each diffuser with a solid scent capsule. The diffuser is activated whenever you turn on the air conditioning or heating in your car.

Our lambskin series uses natural lambskin for production. Each piece of genuine lambskin comes with its own unique texture and shine, meaning that variations in texture and gloss across different units are normal.

On one hand, many car fragrances on the market contain antioxidants to maintain both their scent and color. Our sachets, however, do not include antioxidants, which results in a slower oxidation process and consequently uneven coloring. On the other hand, our sachets are made from natural diatomaceous earth, and the surface may exhibit slight color inconsistencies (for example, the "Fresh Grass & Pine" fragrance might show uneven patches of orange). This is entirely normal, so please feel confident in using our product.

At Le Celora, we insist on using premium perfume oils and avoid inferior or overly synthetic fragrance additives. Our formulations are designed to optimize the in-car atmosphere, maintaining a naturally pleasant and subtly elegant scent.

Le Celora diffusers offer a fine fragrance option for your car journey, with a reusable diffuser and a variety of scents to appeal to a range of different tastes. We strive to use the safest, IFRA-regulated and most natural ingredients to create a sensory experience that’s more subtle, refined and less toxic than your average air freshener.

Fragrance is highly subjective—each person's sense of smell varies, so the perception of the same scent differs from one person to another. Ultimately, every individual's experience of a fragrance is unique.

Studies have found that smells can affect a person’s mood, concentration and wellbeing, and we believe Le Celora’s diffuser will improve your overall driving experience and car journey.
