The IKOU Aromatherapy Ultrasonic Diffuser is a 100 ml cool-mist diffuser that runs up to 6 hours continuously or up to 12 hours on intermittent mode. It uses ultrasonic vibration rather than heat, so it disperses oils without warming them, and it shuts off automatically when the water runs out. It also claims a negative-ion output that may help settle airborne dust. It suits anyone scenting a bedroom, office or small living space who wants set-and-forget operation. Against larger tank rivals it trades capacity for a compact 100 mm x 140 mm body, so expect more refills than a 300–500 ml unit.

Rated 4.8 out of 5 from 79 ratings, buyers are largely positive. They like the gentle, even mist and the long intermittent runtime, and the auto shut-off is a common reassurance. The main grumble is how often a 100 ml tank has to be topped up.
This ultrasonic essential oil diffuser disperses oil blends into the room as cool steam. It uses no heat, so the oil's properties are not altered. The mist spreads gently and evenly through the space.
It also generates negative ions, which may help reduce airborne dust and particles. It shuts off automatically when the water is used up. You can set it to continuous or intermittent mode and change oil blends easily.
On intermittent mode it diffuses for up to 12 hours. On continuous mode it runs for up to 6 hours.
