Need a new oil cup for your Whisper diffuser? Here it is! Fill this cup to the fill line with water, add a few drops of your favorite essential oil, and diffuse! If the cup gets dirty, just empty it and wipe it clean with a soft cloth.

The oil cup is made from highest grade PET-1 plastic, and is BPA-free.

IMPORTANT NOTES:

1. The Whisper diffuser requires water both in the base and in the soft cup. (It will not run if the oil level in the base gets too low)
2. Place essential oil in the soft cup only, not in the base. (Oil in the base may clog the diffusing mechanism and damage the diffuser.)
