Good to know

Common questions, answered.

What comes in the box?

Every order ships with Diffuser, Remote control, Power adapter, User manual. Fragrance oil is sold separately so you can choose your own scent.

Is it quiet enough for a bedroom or office?

Yes — it runs on a quiet ultrasonic mist, gentle enough for bedrooms, offices, and calls.

Is it safe to run overnight?

Yes — it shuts off automatically when the water runs low, so it's safe to leave running overnight. It makes cool ultrasonic mist with no heat or open flame.

How much water and oil do I add?

Fill the tank with clean water up to the max line (about 300ml), then add a few drops of water-based essential or fragrance oil. Keep water below the max line for the smoothest mist.

How do I control how long it runs?

Set a timer to shut it off automatically, and top up the tank whenever the mist fades.

What kind of oil should I use?

Use water-based essential or fragrance oils made for ultrasonic diffusers. Add them to the water tank — don't run the diffuser dry or with oil alone.
