[Replacement]We advise our customer to replace the filter after 3-4 months use (depending on usage and water quality).
[How to Use]To see a better performance, we advise user to soak a filter stick to be wet completely before inserting to the humidifier.
[Advantages]Prolong the service life of diffuser: if the diffuser/humidifier is always complete-blocked or half-blocked, it will become hot and become broken easily, we highly recommend you to use water-solubility essential oil and clearwater.
