  • How Do I Clean the Unit After Each Use?

    1. Turn the device OFF and unplug the unit from the electrical outlet. Lift off the top cover and the inner water tank cover.
    2. Drain and rinse the water tank thoroughly to remove any sediment and dirt. Wipe clean and dry with a clean soft cloth or paper towel.
    3. Remove water and clean the water tank after each use.
    IMPORTANT: Do NOT fill with HOT water as this may cause leaking. Remove the water from the tank when the diffuser is not in use.

    Are there any filters that need cleaned or replaced?
    No. There are absolutely no filters to clean or replace.

    Can the Essential Oil be used with any of the PureGuardian® Humidifers?
    NO. The essential oils should NOT be used with any of the Pureguardian® Humidifiers as the plastic needs to be specially treated for the oil. They are meant for use only with the PureGuardian® Aromatherapy Diffusers.
