The Only Diffuser You'll Ever Need!
"I am absolutely blown away with this diffuser. It is so compact and durable and so easy to use! It is quiet and comes with multiple straws so you can keep your scents separate. A great buy!"

5 Reasons Why You'll Love The Sia Diffuser
1. It's 100% waterless
The Sia diffuser uses nebulizing technology that atomizes the essential oil directly from the bottle into micro-fine vapour particles, without needing water or heat. This technology preserves the therapeutic properties within the essential oil resulting in a stronger scent than you’ll get from most diffusers.
2. Diffusers straight from the oil bottle
Attached you favourite bottle of essential oil straight to the Sia diffuser spray nozzle and place it back in for instant powerful scenting and relaxation where ever you go. It can hold a 5ml, 10ml or 15ml oils bottle.
3. Cordless with a long-life rechargeable battery
No matter where you choose to go the Sia is the ultimate portable diffuser, it's completely cordless, waterless and is rechargeable by a micro USB cable. It even has a battery life of up to 70 hours. The Sia is Perfect for around the home, workplace, in the car, the caravan or even on that overseas trip you've been planning.
