The Diffuser

$79.95

An ultrasonic diffuser with a warm amber lamp. Fill the tank, add a few drops of your favourite diffuser oil and let the mist carry the scent into your space.

This one is built for changing your mind. The tank rinses out in seconds, so you can run something different whenever the room calls for it.

Best in the space you spend the most time in, where you will actually notice it. It holds a low warm ambient light and shuts itself off when the water is gone.

How it works

Fill with 140ml water.

Check your undertones diffuser oil bottle for the recommended amount of oil to start with - a little goes further than you'd expect. You can always add more mid-run.

Mist button - press once for high, again for low, again for off.
Lamp button - press through dim, bright, ambient fade, or off.

If the diffuser runs dry, it shuts off on its own. No need to babysit it.

How it works.

A simple device that fills your space with a great smell. It's warm amber light helps set the tone.

01

Pick your scent

Whatever fits the room and the hour. There are no wrong answers, just louder and quieter ones.

02

Add a few drops

Into the water tank or straight onto the rocks. Start with 2 and see how the room takes it.

03

Get on with your evening

The scent does its thing without being asked twice. That's the whole point.

01

Fill the tank

02

Add the drops

03

Press the mist button

01

Drop it on the stones

Straight onto the rocks. No water, no power, no cords. Go a little heavier the first time, they like to soak it in.

02

Put them where you pass by

The scent sits close, about a metre or two. Desks, bedside tables, bathrooms, the entry.

03

Top up when it fades

A few drops a day keeps it going. For a new scent, let the old one fade out over a week or rinse the stones and start again.

Full instructions come in the box. Questions any time at hello@undertones.com.au.
