More info

Practical and discreet, you can take this ultrasonic diffuser with you for days in the office, on the move, at home or even in some cars.

The Keylia diffuses your essential oils right next to you while maintaining all their benefits.

With its 3 different diffusion power levels, it emits small jets of mist at regular intervals and lets you adjust the diffusion effect.

Thanks to its misting technique, it can diffuse over up to 10m².

User tips for the Keylia USB diffuser

Remember to check that the tank isn’t empty if you see no more mist coming out.

Point the outlet upwards for better diffusion.

Do not allow to diffuse for more than 20 minutes so as not to saturate the air.

Do not put your diffuser or wick anywhere they are likely to corrode.

Looking after your Keylia USB diffuser

To clean your diffuser, you must first disconnect the USB key. Then, with a cotton swab soaked in pharmaceutical alcohol, clean the outer parts, the cap head and bottle space. Finally, remember to wash your hands after replacing and cleaning your diffuser.


Do not activate the diffuser in the presence of children under 3 years or pregnant women. In a child's room, we recommend that you do it when they are not there, and at least 30 minutes before they come in.
