How is a nebulizing diffuser different from an ultrasonic one?

It atomizes pure essential oil instead of mixing oil with water. Scent is stronger and undiluted, but it uses more oil and gives no humidity.

No. You fill the glass bottle with essential oil only. There is no water tank to fill or clean.

Can I run it all night?

It has continuous and intermittent modes plus an automatic shut-off timer. Intermittent mode stretches the oil and suits overnight use.

The wooden base, glass diffuser bottle, directional cap and power supply.

The bottle is small and nebulizers consume oil quickly, so expect to refill more often than a water-tank diffuser, especially on continuous mode.

It is described as quiet, but nebulizers generally produce more of a soft pump hum than near-silent ultrasonic models.
