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.

With its long-life changing LED lights, it will set the mood being with a loved one and help the kids to get to sleep. Set the light to your one favorite color, turn it off, or let it cascade through all the colors.

The unit is whisper-quiet at about 36 dB with no beep tones setting it on continuous with the red light or green light for intermittent settings. When it is low on water, it will shut off automatically.

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.

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.

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!
