How long does one Fresh Box last?

Duration varies based on cabin size, ventilation, and how much you drive. The solid formulation is designed for extended release—expect several weeks of noticeable scent before it loses potency.

Will this interfere with my existing air freshener or cologne?

Lavender plays well with most scents, but if you already run a strong fragrance, the two will blend. Test it in your car first—you can always remove it if the combination isn't right for you.

Can I place this anywhere in the cabin?

Yes. Cup holders, door pockets, under seats, or on the dash all work fine. Just keep it away from direct sunlight if you want maximum longevity. Heat will accelerate the scent release.
