Keep the unit away from any electonics sensitive to water.

    To Fill:
    Make sure unit is unplugged.

    1. Separate the top cover from the main body of the unit.
    2. Using standard tap water, use the measuring cup to fill the water into the water tank. DO NOT fill the water beyond the MAX level mark of measuring cup. Diffuser will not work if filled beyond the MAX level. Important: Do NOT attempt to fill water into the diffuser without removing the top cover.
    3. Add 3-5 drops of essential oil. Important: Avoid adding too many drops of oil.
    4. Return the top cover.
    5. Connect the power adapter to the unit. Plug into electrical outlet.
    6. Press the power button to turn the diffuser on.

    The unit operates using Ultrasonic Technology:
    The advanced ultrasonic technology used produces vibrations at a high frequency, turning the water into mist, creating a soothing atmosphere.

  • How Do I Clean the Unit After Each Use?
    To clean the unit and prepare it for use again:

    1. Turn the device OFF and unplug the unit from the electrical outlet. Lift off the top cover.
    2. Drain and rinse the water tank thoroughly to remove any sediment and dirt. Wipe clean and dry.
    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.

Cute & Simple

Works great and is super cute!

Remains Clean and Emits Glorious Lasting Aroma Evenly

For all you "Diffuser Pals" I have some good news tried and true by me ... Dottie! I have a Pureguardian spa ultrasonic Essential oil diffuser ... and I use it every day and every night. I use a q-tip with alcohol to clean the little circle plate inside at the bottom of diffuser. I will also put a little alcohol on a napkin and gently wipe the inside. Sometimes if I notice the stream isn't full throttle I will clean and put in plain filtered water and add just a tiny pinch of pink Himalayan salt and run the diffuser to remove any oil that might be partially plugging the steam port. By caring in this way it will keep your machine efficient and quiet and last longer. This is a really wonderful machine and does not stain when using oils and evenly disperses throughout the room with so much healthy scent and satisfaction. Pureguardian is a dollar worthy purchase and less expensive than other machines I have used in the past. My husband bought me a new one for Christmas because I love it so.
