Why switch
Retire the dangly tree.
Cardboard trees fade in a week. Gels go gooey on a 40-degree day. Sprays last about a minute. The Halo mists a little at a time, so the scent stays steady from your driveway to wherever you're headed, at the strength you pick.
The old way
- Fades within a week
- Goes gooey on a hot day
- Swings off the mirror
- One strength: too much, then nothing
The Halo
- Steady scent, every drive
- Nothing to melt in summer
- Clips to the vent, out of sight
- Light, medium or strong: your call
Three strengths
Light, medium or strong. Your call.
Tap a strength to see how the Halo glows. On the real thing, it's one press of the button.
For short trips, sensitive noses and the passenger who always says "bit strong, isn't it?"
For the commute, the school run and the Saturday sport shuffle.
For long drives, the dog after the beach and the footy kit that's been in the boot since the weekend.
Set-up
Set up in under a minute.
No tools, no cords on the dash. Charge it with USB-C, clip it on and top it up when it runs low.

Customer Reviews
Works really well. bought a second one as a gift. 1 month in and battery still holding up on the first charge (using on low setting).
Very good. The best air freshener I've ever had. Could you create a fourth setting of 1 hour on and 1 hour off to continue scenting the car while it's parked...as an option! That way I could get the car already scented in the morning. Just an idea.
Great air freshener. been running in my ev (mach e) for about 2 weeks on low setting. the channel smells great and bottle still looks pretty full!
Super delivery, haven't used it yet, I think everything will be like last time, this is already my second order. I recommend it. Thank you.
It lasts a long time if you set it to 90 seconds. I love the scent of the fragrance. I have it in both cars with the same smell. I recommend it 100%

Read our refund policyGood questions
Will it fit my car?
The clip fits most standard air-vent slats, from hatchbacks to SUVs and utes, and keeps your cup holders free. If your car has round or unusual vents, check the photos before ordering. If it doesn't suit your car, our 14-day money-back guarantee has you covered.
Is it OK in a hot Aussie summer?
Yes, there's no gel to melt. Like any battery-powered gadget, though, don't leave it sitting on the dash in full sun when you park. Pop it in the console or glovebox.
How long does the scent last?
It depends on the strength and how much you drive. You only need a few drops per fill, so the 3 bottles in the box go a long way. When the water runs low, just top it up.
Can I use my own perfume?
Yes. Fill the bottle about three-quarters with water, add a spritz or two of your favourite perfume or a few drops of any fragrance oil, and screw the Halo back on. Start with a little and add more if you'd like it stronger.
Does it run all the time?
No. A built-in motion sensor starts the mist when you get in and drive, and lets it rest when the car is parked, so it isn't misting into an empty car all day.
Does it get rid of bad smells?
It fills your car with fragrance, which covers everyday smells like takeaway, gym gear or a wet dog. It doesn't clean the air, so for a lingering smell, find and remove the source first.
Is it a good gift?
It's an easy one to get right: almost everyone drives, and it looks good out of the box. The 2-pack is made for it: one for them, one for you. Order by 1 December for delivery before Christmas.
How long does delivery take?
Delivery is free anywhere in Australia and usually takes 8–15 business days, with no customs fees at the door. You'll get a tracking link by email as soon as your order ships.
What if I don't like it?
Let us know within 14 days of delivery and send it back unused, and we'll refund you in full. Faulty or damaged items are covered under the Australian Consumer Law, and we'll replace or refund them.
Make the next drive the nicest-smelling one yet.
