How is a nebulizing diffuser different from a water diffuser?

It atomizes pure oil into the air with no water or heat, so the scent is undiluted. Water and ultrasonic diffusers dilute oil and add humidity.

Which oil bottles fit it?

It accepts 5ml, 10ml and 15ml essential oil bottles screwed directly on, or you can add your own blend to the reservoir.

Does it work in large rooms?

The maker says it suits both large and small rooms, with touch modes to raise or lower output. In a big space, run it at a higher intensity.

Is it quiet enough for a bedroom?

It is designed to be whisper quiet, so it should not disturb sleep at low settings. Nebulizers are generally louder than ultrasonic models at maximum output.

Can I use it in a car?

Yes. Its base fits a standard cup holder, and it is portable enough to move between car, room and travel bag.

Does it need cleaning?

There is no water tank to scrub, but oil residue builds up in the nebulizer, so the nozzle and reservoir need periodic cleaning to keep the mist strong.
