This is a titanium - gold alloy replacement ultrasonic disc for the doTERRA Lotus diffuser.
If your diffuser is not producing an acceptable amount if mist or not functioning at all, then it's time to replace the ultrasonic disc.
Replacing the disc is a fairly simple process, just disassemble the unit and unscrew the retaining ring that holds the disc in and replace.
Re-assemble the unit in reverse order. If you do not already have a tool set we recommend purchasing the 3mm screwdriver along with this disc. (SKU:0000015)
