Waterless essential oil diffusers operate differently from water-based ones.

As the essential oil evaporates inside the diffuser over time, it inevitably adheres to the inner walls.

Over time, this can clog the diffuser, preventing the mist outlet from discharging properly.

If there is no fragrance or mist after using it for a while, you can try cleaning the aromatherapy machine first.

It may be that the inner wall of the machine is clogged due to long-term atomization.

It does not mean that the function of the machine itself is damaged.Does the sound inside the machine mean it's broken?

No. The sound inside the machine is due to the leak proof bead design inside the machine. All of our machines have this sound. The function of leak proof beads is to prevent essential oils from leaking out of the atomization hole in a short period of time.

All of our machines produce this kind of sound, you can check out our video:
