The Custom Car Diffuser by SWID Perfumery is a personalized, vent-clip car fragrance system that lets you choose your own scent from SWID’s library of fine perfume oils.
- Fragrance oil capacity: 8ml per refill cartridge, lasting approximately 30 days under normal use
- Clip-on design fits all standard automotive air vents without adhesives or permanent mounting
- Scent is fully customizable — choose from over 40 fragrance oil options in SWID’s catalog
- Diffuser body is made from matte-finish ABS plastic with a stainless steel clip mechanism
- Refillable system: the cartridge swaps out so you keep the housing and just replace the oil pad
This product is built for drivers who want a specific scent in their car, not whatever’s on the shelf at a gas station — it’s a practical pick for fragrance enthusiasts, gift buyers, and anyone tired of synthetic pine-tree air fresheners.
Unlike disposable hanging fresheners or generic reed-style car diffusers, the SWID Custom Car Diffuser uses the same quality fragrance oils found in the brand’s personal perfumes, and the refillable design cuts down on waste over time. You’re not locked into one scent forever, either.
