Ultrasonic Essential Oil Diffusers – The Best Choice By Far

When you use aromatherapy, you will find it refreshing for home or anywhere when you use it with an Ultrasonic Essential Oil Diffuser. This remarkable diffuser is the best by far in today’s marketplace. This particular Ultrasonic diffuser receives reviews of praise for its therapeutic benefits and pleasant aroma.

The Ultrasonic diffusers are a special type for dispensing essential oils into the air. Using high frequencies, the unit separates the essential oils into small particles producing a micro-mist that is circulated into the atmosphere in your favorite room. Negative ions are released that give you a sense of well-being, mood is uplifted, and stress is lessened. The mist stays in the room environment for many hours depending on how long you set the timer on the unit.

Compared to the cold unit, nebulizer unit, and heat unit diffusers, the Ultrasonic diffuser uses less oil than does cold diffusers. Nebulizers use more oil, and heat diffusers do not do as good a job for therapeutic results. The advanced Ultrasonic diffusers are leaders in the marketplace and for good reason. Ultrasonic diffusers purify your environment wherever you use it and they deliver therapeutic results. The essential oils used in an Ultrasonic diffuser purifies the area, removes offensive odors, moisturizes dry flaky skin, soothes and moisturizes dry sinuses, and is refreshing to mind, body, and soul.

Why Should You Choose the Ultrasonic Diffusers Over Others?

There are many reasons for doing just that—choosing an Ultrasonic diffuser before all other diffusers. Diffusers are not created equal, as you will see from the information we have compiled for you below.

Ultrasonic diffusers—

  • Use smaller amounts of essential oils to achieve a powerful fragrance result.
  • Purify and deodorize the air you breathe in. This helps allergies, hay fever, respiratory, and asthma sufferers.
  • Improve well-being producing negative ions that communicate with serotonin in the brain known for relieving stress, anxiety, headache, and fatigue.
  • Dispense a mist full of moisture that humidifies the air you inhale. This is a benefit in dry climates or when heat sources operate in the wintertime drying out the air. Air conditioning also dries the inside environment removing the ambient moisture from the air surrounding you.
  • Separate the essential oil particles into micro-particles to circulate with water then disperse into the room area for a micro-fine mist.

The Ultrasonic essential oil diffuser is the best of the best in your home, bedroom, bathroom, office, spa, salon, or professional setting.

Add water to the Max line never overfilling. Purified or distilled water is best to use to avoid plugging up the unit from tap water with minerals. Tap water creates mineral and lime scale build up. If this happens, unplug the unit from the bottom base and wall outlet. Use a little distilled clear vinegar with water and run it through the unit for about 10 minutes and with a cotton swab, carefully clean corners, and rinse thoroughly, air dry, and start using the unit again. Another method is after you use your unit about 3 times, first unplug the unit from the base. Fill the water reservoir up to the Max line with water and one tablespoon of citric acid (sour salt) or two tablespoons of distilled vinegar. Use a cotton swab to clean after letting the mixture soak 5 to 10 minutes. Pour out the solution being careful not to let it get into the air outlet hole on the side. Never submerge the unit in water. Allow the unit to air dry or use a towel to dry it inside and out. Mildew and bacteria will grow in your diffuser if you let water sit inside for days and weeks. Always leave it clean and dry when not in use.

The dimensions are 6.42-inches high x 3.94-inches in diameter and weighs about 1 pound.

    Have you heard of the Saje line of Nebulizer products? They are a Canadian brand. I am looking to buy one as I am a big fan of all of their other products. If you have any info on their nebulizers (if you’ve used them or know anyone who has) that would be great! Thanks!

    1. Melissa

      Hi Roxanne,

      Saje® is indeed a Canadian company since 2015 with 34 locations across Canada and a growing web presence. Their products are not listed on Amazon our affiliate. You will have to purchase directly from Perhaps others know the nebulizer and will discuss it here for you to see.


    2. Lori Conner

      I just Looked at some at Wanderlust. What do you think of the Saje line.

      1. Melissa

        Hi Lori,

        I do not know of the Saje line. Sorry.


  2. Rose Forgy

    I am looking for an ultrasonic diffuser that has no plastic parts that the oils will touch. something that is made of glass, stainless steel or ceramic

    1. Melissa

      Hi Rose,
      Most diffusers are made with BPA-free plastic for holding the water. The Aromyst™ Ultrasonic Glass Diffuser at our website here is glass.
      Another page here shows more diffusers that will give you other options than plastic.

      Best regards,

      1. Stathis

        Unfortunatelly the inner water reservoir is made of plastic….

  3. David

    Your article/reviews came up in a search, but I’m looking for something more specific.
    Can you/others recommend a diffuser that can hold a larger capacity, can be set to run at least 4 hours or -more- apart?

    Basically: it’s for a senior, who’s not always mindful, and family would take care of refilling every 2-4 weeks. Usage is low / not a lot of square footage.

    Would a terra cotta ring, hanging, or on a lamp be a better choice?

    Thank you,

    1. Melissa

      Hi David,

      I’m not too familiar with terracotta rings or anything that hangs. You might look at diffusers here for capacity and length of running time. Refilling is when the water is gone and that depends on how long it runs. Read these, look at the pictures, and one of them will work.

      Best regards,

  4. Lisa z Kendra

    I saw the DōTERRA Aroma Lite list the microns. Can I assume the other diffuser is around 1-4 microns?

  5. Melissa

    Hi Kaytie,

    I will choose Amir 100ml.


  6. Yolande

    I just received a Saje ultrasonic diffuser as a gift and it doesn’t always mist. The water is just below the max line and it’s bowling and has a lot of mist when I lift up the top part of the diffuser but the mist doesn’t come out of the hole on top!!! It is not block… worked yesterday but not working now. Help!

    1. de

      Take a spoonful or two of the water out. I’ve had this problem when water was just at the max line, lots of mist inside but not exiting the opening. Removed a bit of the water, added another drop of oil and whalla, it worked!

  7. Vinny

    Do any of these work off a wall switch? I’m into home automation and want it to turn on when I get home.

  8. Kerrilyn
