Everyone experiences stress; after all, it’s a normal part of life. Whether you have too much on your honey-do-list or you just need more sleep, the HoMedics® Ultrasonic Aroma Diffuser will help boost your energy level as it quiets your mind and eases your spirit.
The Aroma Diffuser’s color-changing glow creates a peaceful ambience while delivering a fine mist of natural aroma to transform any environment. Its humidifier feature helps alleviate dry air to create the ideal moisture level in your space. Plus, a convenient remote control allows you to customize your aroma experience from a distance.
Simply fill the diffuser to the max fill line and add 5-7 drops of 100% pure, therapeutic-grade essential oil (2-pack sampler included) to the water. Then revel in 7.5 hours of continuous runtime, or 15 hours of intermittent use. Enjoy a library of relaxing sounds without worry — the diffuser will power down on its own when the water tank needs to be refilled.

Customer Reviews
Ultrasonic Aroma Diffuser is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Bought 1 and went back and bought 2 more! Like a previous reviewer said, she bought hers at Ross and so did I! 2 were priced for $24.99 and one was priced for $ I bought the cheaper one :) I opened it maybe 3 hours after I purchased it and I immediately fell in love with it! I have one I travel with, that was given to me as a gift and I love it (different brand). Anyway, I wanted to go back to the store and buy the other 2 I saw. 20 minutes before closing, i zoomed to the store. I took the box and receipt to show the price difference and the lady brought the price down for me! I am so happy, now I have an amazing Christmas gift to give! It is totally worth buying!

Rated 5 out of 5 by from Such Fabulous little spa find ! I bought this little diffuser at Ross for $24.99 regular $60! I wasn’t sure what exactly I was getting. I had purchased one on the past and wasn’t impressed. This little spa machine was impressive. It has 6 different soft ambient color changing features. It plays 3 lovely relaxing sounds, relaxing spa, lovely relaxing piano and soothing ocean waves.And it has volume control as well.One of the great features is the 7.5 hours of running time. Such a great find you will be IMPRESSED!

Q & A

Just opened and set this up. The colors and sounds work, but not the diffuser. What could the problem be?

Asked by: Susan Y
We would recommend cleaning the reservoir with a 50/50 vinegar and water solution. Sometimes the diffuser will have a small amount of dust that settles in the reservoir from the packaging. We also recommend making sure the water is not able the "max" fill line located inside the reservoir.
