    3. 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.

    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?

    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.

Great product

Love the diffuser but it's started flashing red then shutting off, can't figure out why.

A Statement In My Room

I got the Aromatherapy Essential Oil Diffuser as a gift for my birthday, and I couldn’t be more pleased. Just a couple drops of oil into the water and my bedroom smells amazing. I like that’s its small enough to fit on my nightstand and quiet enough to leave running through the night.

With Christmas around the corner, I think PureGuardian Diffusers with make great gifts for friends and family.

PureGuardian Ultrasonic Aromatherapy Essential Oil Diffuser

This essential oil diffuser is perfect for use in any room in your home, and small and light enough to travel easily. Easy to follow directions indicate how to use the diffuser -plug the cord into the bottom of the unit then using the pre-measured small cup you add water to the center of the diffuser to the 'MAX' line that is marked in bold black print so it's easy to see. You add 3-5 drops of your favorite essential oil, place the spout on top, and then the green plastic cover on top of that. A simple push of the button gives you a soft, gentle and quiet mist. A second push of the button gives you a color-changing night light that goes while the diffuser is misting. A final third push of the button turns everything off.

The diffuser cleans easily, and holds enough water to last at least 10 hours. I was pleasantly surprised that a small bottle of lavender essential oil was included in the box with the diffuser, that was a nice little bonus. I really like the looks of it - it has an elegant yet fun design. The bottom is sturdy and wide and does not tip easily which has been a problem with my other diffuser.

Nice compact diffuser for the TV room.

When we come home from work we automatically head for the couch and recliner since we both have exhausting jobs. (OK, who doesn't??) I have other diffusers, and I must say that this is a nice one. It works quietly, and I love the color changing feature, although the colors are a tad distorted by the green of the cover. The operation is easy and efficient as long as you use another essential oil other than the one enclosed because the fragrance of it is almost nonexistent! It really does add a feeling of relaxation to the room.

A great product

What a great product! It runs silently and does last for 8 hours. Just use tap water and add your favorite scent. You can change the oil to something different daily and as long as you rinse and dry the unit, there is no overlap of aroma. You can run just the diffuser or the diffuser with lights. If you are using in a larger room (say bigger than a bedroom), just add a few more drops of oil so the smell doesn't get lost. Would make a great gift!
