Perfect Scents plug-in refill air freshener – Mountain Air (3 packs of 3×20 ml)
If your car’s picked up that damp, wintery whiff or just smells a bit tired, these plug-in refills are a straight-up, no-faff way to keep things smelling fresh. They’re made for 3volution-style plug-in units and deliver a clean, pine-forward Mountain Air scent that’s familiar without being overbearing.
What this is
These are refill cartridges only — not the plug-in unit itself. They’re for anyone who already owns a compatible 3volution device and simply wants to swap the scent. The box includes three packs, each containing three 20 ml cartridges, so you get nine cartridges in total — plenty to see you through a few seasons.
Why you might like it
- Quick and simple: pop a cartridge in and the unit does the rest — no fiddly setup or faff.
- Crisp pine aroma: Mountain Air gives a neat, outdoorsy pine scent that suits cars, small rooms and workspaces without overpowering them.
- Handy bulk packs: three packs of three means fewer trips to the shops and spare cartridges when you need them.
Typical use cases
- Freshen the interior after weekend trips that leave the car smelling a bit damp or musty.
- Keep a small office or desk nook smelling pleasant without annoying colleagues.
- Perfect for boot spaces, storage cupboards or sheds where smells can build up — a small cartridge goes a long way.

Things to consider
Compatibility is key — these refills are designed for 3volution-style plug-in units, so double-check your device before buying. Lifespan varies with device settings, ventilation and how often you run it, so heavy use may drain a cartridge faster than you expect. They’re simple to fit, but don’t force a cartridge into a non-compatible unit.
All in all, these refills are a cost-effective, no-nonsense way to keep a steady pine scent in your car or small spaces. Keep a pack in the glovebox or shed for quick swaps when the current scent fades — a handy little win for everyday freshness.
