Ultrasonic Diffusers

Similar to nebulizing diffusers, ultrasonic diffusers also disperse oils by breaking them into smaller particles. The only difference is the addition of water. These diffusers use a mix of water and essential oils to create a cool mist. They are, however, not as powerful as the nebulizer diffusers due to the mild concentration of oil in water.

Ultrasonic and Nebulizers Diffusers

Ultrasonic diffusers double up as humidifiers in wintertime. This is a great advantage for this type of diffuser. They come with a music setting that cuts down on the noise they make. These aromatherapy diffusers are less expensive than Nebulizers are.

Check out the comparisons done below for the top 5 best ultrasonic essential oil diffusers. Most aromatherapy diffusers are quite good today. Usually any problems will be in the working parts and most manufacturers will guarantee their products when you send them back with your concerns.

All ultrasonic diffusers are 5-in-1 units; they are an essential oil diffuser, a small humidifier with or without oils, a night light, air purifier, and an ionizer producing negative ions that are beneficial in the bloodstream increasing our levels of serotonin in the brain to relieve depression, anxiety, and stress, boosting our energy levels.

Here are a few thoughts for beginners and others who are new to essential oil diffusers:

  • Diffusers are not machines! Ultrasonic diffusers use water, yet manufacturers call them “waterless,” a misnomer that is misleading. Nebulizers are waterless using only pure essential oils.
  • Back to “machine”—sewing machines and lawn mowers are machines. Maybe one day we will invent the time machine and go into our past or future!
  • Diffusers are small units using electricity to emit and diffuse oils into your environment.
  • A small diffuser actually adds a small amount of moisture (humidity) to the air.
  • A diffuser is not an “air conditioner” and do not function As that. Air conditioners are large units usually attached to a furnace to make the house or building cool removing moisture.
  • Ultrasonic units do not use filters.
  • Diffusers emit a cool-mist and have no heating element. Besides, if they did warm the water, it would be cool by the time it hits the air.
  • Being a cool-mist diffuser, there is no heat to destroy the benefits of your 100% pure essential oils.
  • Odors are not masked with diffusers—they are eliminated.
  • Diffusers operate on alternating current (A/C) not direct current (D/C). Direct current uses batteries and these listed here do not operate in a vehicle that uses a battery.
  • Direct current (D/C )is unidirectional (one direction) of flow of an electric charge. Direct current is produced by sources such as batteries, power supplies, thermocouples, solar cells, or dynamos. The current in your home is alternating—it flows back and forth; thus, the name, alternating.

It comes in dark brown made of plastic PP (polypropylene) and ABS (acrylonitrile-butadiene-styrene) and is BPA (bisphenol A)-free. The plastic is a faux wood grain and not real wood.

5. ASAKUKI Ultrasonic Cool-Mist Essential Oil Diffuser, 300 mL

ASAKUKI™ Ultrasonic Cool-Mist Essential Oil Diffuser, 300 mL

The ASAKUKI—Japanese for air in the morning—is a lovely form for a diffuser with a faux wood grain base and a white chimney influenced top. It’s so elegantly designed as shown on Amazon.com®, item model number ASKDF0130, is affordable and you want one!

The diffuser is not “waterless” using 300 mL (10.14 ounces) of water to the max line to cover about 450-square feet. For a heavenly fragrance and therapeutic benefits, add 2-8 drops of 100% pure essential oils (not included).

The 7 LED lights cascade through all the colors of the rainbow that I love! You can also set it to one color that you or your child will love. If you like a pitch black dark bedroom as I do, turn them off. They can be set to dim or bright to your liking.

The water will give you negative ions the same as rain, a shower in the bathroom, and waterfalls do. Negative ions lift your mood and many essential oil essences do as well. Enjoy the calm and peaceful feeling you will have.

The device is a 5-in-1 unit: diffuser that is a small humidifier, an ionizer, an air purifier, and a night light. All ultrasonic diffusers using water are 5-in-1 devices!

It will never overheat causing safety issues because it shuts off automatically when the water is gone.

The diffuser is useful in many places with its many functions.

ASAKUKI™ Ultrasonic Cool-Mist Essential Oil Diffuser

Stale food odors will disappear along with pet and smoke odors. The whisper-quiet unit can run 24/7 if you want it to. It will mist your area for 8-hours with you selecting the hours you want on the front buttons.

It is made of PP (polypropylene), ABS (acetyl butylene styrene) and PC (polycarbonate) plastic and is BPA-free being safe for babies and youngsters and you too. Even though you don’t drink from it, most people like plastics to be BPA-free.

My side note: Baby bottles are made from these plastics, but its smarter to use glass for infants and babies. When you breast feed your baby, the source of milk is the purest and best. When you use a breast pump to store your milk, I recommend glass—I’m a mom too!

Set the timer to run continuously, or 60- 180- or 360-minute cycles as you like it best. It does beep for some of the functions and the sound is very low.

The measurements are 4.76-inches tall x 6.6-inches across the bottom base.

Plug the UL® listed cord into a 110/120-Volt, 50/60-Hz receptacle in North America for USA and Canadian users. All other countries will need to buy a 220/240-Volt adapter to have it operate.

Gift-wrapping is available for friends and loved ones. It comes with a User’s Manual, A/C adapter, measuring cup, and manufacturer’s 6-month money-back guarantee with a 1-year Warranty. There is no risk with this, so you have nothing to lose. It’s made in China.

Final Thoughts

The first thing I want to mention is the word “waterless” that the manufacturer’s use in their Amazon description. An ultrasonic diffuser is not “waterless” because it uses oil with water. What they think they mean is that when the water is gone (“water-less”) it shuts off automatically.

I hope you like this review I did for you and that you find the best ultrasonic diffuser just for you or someone at Christmas, other holidays, or any occasion. These are really pretty to look at while dispersing essential oils into the air. Happy shopping!
