Why I Love Ultrasonic Essential Oil Diffusers and Why You Should too

In recent years, essential oil diffusers have gained popularity for their ability to disperse delightful scents throughout homes, creating a soothing and relaxing atmosphere. Among the various types of diffusers available, ultrasonic diffusers have emerged as a preferred choice for many due to their numerous advantages. In this article, I will explore why I love ultrasonic essential oil diffusers as I believe they are best suited for home environments and provide you with the basics of how to use essential oils in these diffusers effectively.

Why Choose Ultrasonic Essential Oil Diffusers?

Ultrasonic diffusers work by using electronic frequencies to create vibrations that break down essential oils into microscopic particles. These particles are then dispersed into the air as a fine mist, providing a gentle and consistent aroma throughout the room. Here are some compelling reasons why ultrasonic diffusers are ideal for home use:

  1. Whisper-quiet operation: Ultrasonic diffusers operate silently, making them perfect for use in bedrooms, living rooms, or offices. The absence of noise ensures you can enjoy the aroma without any distractions or disturbances.

  2. Humidifying properties: In addition to diffusing essential oils, ultrasonic diffusers also act as humidifiers. They release moisture into the air, helping to alleviate dryness and improve overall air quality within your home.

  3. Preserves oil properties: Ultrasonic diffusers use cool mist technology, which prevents the essential oils from being heated. This helps preserve the integrity and therapeutic properties of the oils, ensuring you receive their full benefits.

Understanding Essential Oils for Ultrasonic Diffusers

Essential oils play a vital role in aromatherapy, which uses natural plant extracts to promote physical, mental, and emotional well-being. These oils are highly concentrated and are extracted from various parts of plants, such as flowers, leaves, stems, and roots.

When used in ultrasonic diffusers, essential oils are dispersed into the air as a fine mist, which can be inhaled and absorbed by the body. This allows the oils' therapeutic properties to be experienced through the sense of smell and, in some cases, through the skin.

There are many benefits to using essential oils in aromatherapy, including:

Relieving stress and anxiety. Aromatherapy can help you relax and relieve stress. It’s been proven to lower blood pressure, heart rate, and muscle tension; reduce anxiety, depression, and insomnia; boost the immune system; relieve headaches; improve memory; and even fight cancer.

Improving sleep quality. The right essential oil can help you fall asleep quicker and get more restful sleep every night. Aromatherapy also helps with jet lag by promoting relaxation while traveling.

Fighting colds and flu. Essential oils have antibacterial, antiviral, antifungal, and anti-inflammatory properties that support your body’s natural defenses against germs that cause illnesses like colds and flu.

Improve memory function. Bergamot essential oil has been used for centuries to improve memory function due to its ability to stimulate brain function without causing side effects or drowsiness like prescription drugs do.

Pain Relief. Some people use the oils for pain relief, although this isn't recommended for everyone. They may also help reduce inflammation and itching when applied directly to the skin.

Each essential oil has unique properties and benefits, so selecting the right oil for your needs is essential.When selecting essential oils for your ultrasonic diffuser, choosing high-quality oils is crucial to ensure optimal results. Look for oils that are 100% pure, organic, and free from synthetic fragrances or chemicals.

The Basics of Using Ultrasonic Diffusers

Choosing the Right Water for Your Diffuser

When using an ultrasonic diffuser, the type of water you use can have an impact on its performance and longevity. Here are some considerations for selecting the right water:

Exploring the Benefits of Distilled Water

Distilled water, which has undergone a purification process to remove impurities and minerals, is often recommended for use in ultrasonic diffusers. Here's why:

a. Prevents mineral buildup: Distilled water lacks minerals like calcium and magnesium, which can accumulate and create deposits in the diffuser over time. These deposits can clog the unit and affect its ability to disperse essential oils effectively.

b. Preserves the diffuser: Using distilled water reduces the risk of mineral residue settling on the internal components of the diffuser, thereby extending its lifespan.

c. Ensures a clean mist: Distilled water produces a pure, clean mist without any impurities or residue, allowing the essential oils to disperse more evenly throughout the room.

Alternatives to Distilled Water

While distilled water is ideal, it may not always be readily available. In such cases, you can consider these alternatives:

a. Filtered water: Using filtered water can be a suitable option if you have a reliable water filtration system. It helps remove some impurities and minerals, although not as effectively as distilled water.

b. Tap water: If the tap water in your area is of good quality and not excessively hard, it can be used in a pinch. However, be aware that minerals present in tap water may accumulate over time and require more frequent cleaning of your diffuser.

c. Spring water: Natural spring water can also be used, but ensure it is high-quality and free from contaminants. Avoid using flavored or carbonated spring water, as additives may interfere with the diffuser's performance.

Remember to avoid using hot water in your ultrasonic diffuser, as it can interfere with the diffusion process and potentially damage the unit. Stick to room-temperature water for the best results.

By choosing the right water for your ultrasonic diffuser, you can ensure optimal performance and maintain the longevity of your device. While distilled water is recommended, alternatives like filtered water or suitable tap water can be used as well, depending on availability and water quality in your area.

Essential oil dilution guidelines for ultrasonic diffusers

Determining the ideal number of drops per 100 ml of water

The first step to determining how much essential oil to add to your diffuser is determining how many drops you want in each 100 milliliters (ml) of water. If you're using a small ultrasonic diffuser, you may want to use more drops per ml than if you were using a larger diffuser with a reservoir that holds more water.

Adjusting the concentration based on personal preference

After determining how many drops per 100 ml, you can adjust it based on your preference. For example, if you prefer using more drops per ml, then add more drops and vice versa.

Recommended diffusing time per session

The recommended amount of time to diffuse essential oils is 3-5 minutes per session. The average person inhales about 1 liter of air per minute, meaning it takes 5 minutes for them to inhale the same amount of essential oils that they would inhale in only 1 minute if exposed to them directly.

Factors to consider when determining diffusing duration

Here are a few things to keep in mind when deciding how long to diffuse your essential oils:

  • The size of the room you’re diffusing in

  • The number of people in the room with you (the more people, the longer you should diffuse)

  • Your personal health and safety concerns (for example, if you have high blood pressure, don’t overdo it!)

Maintenance and Care for Ultrasonic Diffusers

Ultrasonic diffusers are easy to use, but they do require regular cleaning. The oils and water in the diffuser can build up over time, reducing the effectiveness of your diffuser.

Here are a few tips for keeping your diffuser clean:

  • Clean the ceramic disc at least once a week by wiping it with a damp cloth or running it under warm water.

  • Use filtered water to fill your diffuser. Tap water contains minerals that can harden overtime on the ceramic disc and interfere with its function.

  • When filling an ultrasonic diffuser with water and essential oils, use distilled water to help keep mineral deposits from forming on the ceramic disc.

  • Do not use harsh chemicals or abrasives such as bleach or Comet® to clean your ultrasonic diffuser; these products will damage the unit's circuitry and may void its warranty.


In general, ultrasonic essential oil diffusers effectively introduce the therapeutic benefits of essential oils into your home environment. They come in various shapes and sizes, are fairly easy to use and clean, and help combat allergens. Whether you want all the benefits of aromatherapy right at home or seek to replace traditional incense with a more eco-friendly alternative, an ultrasonic essential oil diffuser is a good choice.
