Why do we need to clean our aromatherapy diffusers regularly?

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.

Because the air pump tube is prone to detachment during transportation. So you need to disassemble the machine, reinstall both ends of the air pump tube, and the machine will be able to produce fog normally. If you need a video, please search for the link on the image to view the video
