Search for this question and you will find claims of "up to six weeks". In practice, how long a paper air freshener smells depends on the fragrance strength, the temperature in the car and how the air freshener is opened. Here are the honest numbers for BUGO DUFT air fresheners and what they mean if you hand them out with your logo.
Fragrance life: the short answer
As a guide for our cellulose air fresheners:
- **Normal intensity:** clearly noticeable for about 5–7 days
- **Intense fragrance:** clearly noticeable for about 7–9 days
After that the scent becomes gradually fainter rather than stopping abruptly. The printed card itself does not wear out: it keeps hanging, and keeps showing your logo, long after the strongest fragrance phase.
What makes the scent fade faster
Heat
A car parked in the sun can exceed 50 °C inside. Heat releases fragrance much faster, so the first days are more intense and the total life is shorter. In winter, the same air freshener lasts noticeably longer.
Airflow
Open windows and a fan blowing directly at the air freshener carry the fragrance away quickly. Hanging it slightly out of the airflow helps.
Opening the packaging completely
Each air freshener is packed individually in airtight film. Once the pack is fully opened, the fragrance starts to release. Opening it only shortly before use, rather than days before hand-over, keeps the strongest phase for the customer.
Sealed shelf life
Unopened, in its airtight packaging and stored cool and dry, an air freshener keeps its fragrance for up to two years. That is why ordering a larger quantity for a whole year is usually safe. Store boxes away from heaters and direct sunlight, and keep the individual packs closed until hand-over.
Normal or intense: which should you choose?
- **Normal** suits shared vehicles, taxis, rental cars and audiences who prefer a discreet scent.
- **Intense** suits car washes, detailing and giveaways where the fragrance should make an immediate impression.
Intense fragrance costs €30 extra per 1,000 pieces. If you are unsure, test both in the sample set before ordering.
What this means for branded giveaways
A business air freshener has two jobs: to smell pleasant and to keep your brand visible. The fragrance phase creates the positive association; the card on the mirror keeps the logo in sight afterwards. Two practical consequences:
- **Hand it over at a good moment.** The strongest scent days should coincide with a positive experience, such as a freshly serviced or cleaned car.
- **Give a reason to replace it.** A QR code or offer on the back ("Collect a fresh one at your next visit") turns the end of the fragrance into a return visit.
Frequently asked questions
Why do some suppliers state several weeks?
Figures vary with test conditions: a cool, closed room gives much longer times than a sunny car. We publish the values our customers can expect in normal use.
Can the scent be refreshed?
The fragrance is absorbed into the card during production and cannot be refilled. A new air freshener is the simplest solution, and a good reason for your customer to come back.
Is the fragrance safe in the car?
The air freshener should hang freely and must not touch the dashboard or upholstery, nor sit in the path of an airbag. Safety data sheets and IFRA documentation are available on request.
