*Diffuser cleaner (sold separately), absolute ethanol, or rubbing alcohol is also applicable.
Diffusing part: Gently remove the dirt adhering the diffusing part with a cotton swab. Excessive force may cause damage to the diffusing part. If it is dirty, please immerse the swab into the diffuser cleaner (sold separately) or absolute ethanol or rubbing alcohol and clean it.

7. Diffusion seems to have become weak. What are the solutions?
(1) Is the oil stick properly installed?
Open the cap at the bottom of the stick holder and install the stick correctly and put the cap back. It may take up to 10 minutes for solo to start diffusing when using this product for the first time or after replacing the oil sticks.
(2) Is 'piezo diffuser aroma oil' missing in the tank?
Please refill 'piezo diffuser aroma oil'. The diffuser may not start diffusing instantly with a small amount of piezo aroma oil since it takes more time for the oil stick to absorb the oil.

Using a cotton swab, lightly wipe the diffusing part. Soak a cotton swab with diffuser cleaner (sold separately) or absolute ethanol or rubbing alcohol to clean the diffusing part if it persists.

Replace oil sticks if you still see a weak diffusion even after (1) (2) (3) procedures above. Contact the sales outlet where you purchased the product if none of the above works.
