How do I hang the diffuser on the mount? Do I need to use screws?
Frequently Asked Questions - 09/05/2026
Response Notice-Facile

No, you do not need screws to directly hang the Vevor A305M diffuser on the mount. The mount is designed to hold the device in place simply by hanging it, with no additional screws required.

Wall mount installation:

  • Mark the position of the mounting bracket on the wall
  • Drill holes at the designated location
  • Insert the expansion bolts (wall plugs) provided into the holes
  • Attach the mounting bracket to the wall with the fixing screws
  • Once the bracket is securely installed, simply hang the diffuser by placing it on the bracket

Essential precautions: According to the Vevor A305M manual, always keep the device in a strictly vertical position. Tilting or placing it flat will cause essential oil leakage, which will damage the diffuser and internal components (atomization core, seals, etc.).
