What is an Essential Oil Diffuser?

Aromatherapy essential oil diffusers are small devices that send the essential oil elements into the air. This favorite method for air purification is to use the wellness approach for receiving the benefits of aromatherapy.

When we breathe in the gentle vapors of the aromatic oils, the fresh, earthy, or fragrant scent not only smells wonderful, but also the relaxing air surrounding us is healing. You do not need a spa or Japanese garden to realize the benefits of aromatherapy softly diffused into your living environment. Not all aromatherapy diffusers are created equal. Look for a quality essential oil diffuser here for the antiseptic and anti-bacterial properties infused within the oils.

What are the Differences Between Humidifiers and Diffusers?

People will sometimes confuse aromatherapy diffusers with humidifiers. Actually, these are two different things. Home humidifiers increase the moisture in the air using large humidifiers that moisturizes the air in large rooms or one that is integrated into the heating system to humidify the entire building or home. They are more often used in dry states in the western United States to add humidity (moisture) to the air, especially in the winter. They are also used in humid climates in the wintertime when the furnace is putting dry air into the house.

Too much humidity can reduce the health benefits of the vital oil components in the diffuser by having too much moisture in the air. A diffuser delivers a micro-fine mist to deliver the healing oil’s essential elements. Dry air can stuff you up, so the diffuser would help to un-stuff your nose.

Top 13 Best Essential Oil Diffuser Comparisons

We have compiled comparable reviews for the top 13 very best essential oil diffusers for you to consider. Many aromatherapy diffusers are extremely good, and many others are second-rate. There are many of these available in the marketplace today; however, the reviews here are based upon the most effective ones evaluated by the marketing team.

  • Diffusers are not machines. A machine is a lawn mower or sewing machine—and maybe a futuristic time machine! These are small units using electricity to emit and diffuse oils into your environment.
  • These units are not air conditioners and do not function as an air conditioner. Air conditioners remove moisture from the air to make the air dry and cool. These cool-mist diffusers provide moisture to the air.
  • Ultrasonic units do not use filters. They disperse essential oils with water into the air providing a cool mist.
  • Diffusers do not mask odors; the oils eliminate odors.
  • Being a cool-mist diffuser, there is no heat to destroy the benefits of your 100% pure essential oils.
  • The diffusers operate on alternating current (A/C) not direct current (D/C). D/C uses batteries (direct current) and these are not that type.
  • 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.

Do you want moisturizing benefits for dry skin? Essential oils can be used in many ways. You can pour a few drops into your tub for a soothing and great smelling bath.

On the other hand, use this diffuser to fan out the vapors with a cooling mist, permitting the extraction of the plant’s chemical properties that have been used for thousands of years by our distant ancestors. The oils will elevate your mood, help you to relax, heal dry skin, and is spiritually uplifting. Below are the many benefits from using a moisturizing diffuser.

1. Air Purification—The diffusing units are not “machines.” A lawnmower is a machine. Therefore, when you read “machine” at other websites, you might get a visual impression of something large. These units are small, portable, and marvelous for breathing clean, purified air, for removing tobacco smoke and other disagreeable odors. The essential oils have anti-microbial and anti-bacterial components derived from Mother Nature’s wonderful plant kingdom to benefit health happy people.

2. Dust Removal—Diffusers are ionizers. Negative ions attract dust particles, allergens, and other substances. With a diffuser, you will have cleaner air. Diffusers can help those people who suffer from dust allergies, dust mites, asthma, and other allergic ailments. Negative ions are another of nature’s laboratory of wonderful things!

A Side Trip About Negative Ions. Negative ions are in the air and might not be love, but are close to it. Colorless, odorless, and tasteless, they are invisible molecules we inhale abundantly. Think about the outdoors—beaches, waterfalls, mountains, the woods, the forests—these are rich negative ion areas and they are around us when it is raining. In the bloodstream, negative ions produce biochemical happenings that increase our levels of the mood enhancing brain chemical, serotonin that helps to remove stress, depression, and increase energy.

3. Help Uplift Mood and Eliminate Stress—Specific essential oils are known to lift a down mood up. These oils also relieve stress and mild depression.

Within a few minutes, you will be experiencing your experience.

6. HumidifierPeople exposed to pollen in the air are sometimes sensitive or allergic to their influences. Nasal allergies are miserable. The mucosa in the nose becomes inflamed and mucous is secreted. Humidification can help with that. The diffuser puts out moist air to alleviate the symptoms with its fine spray mist. It can raise the humidity up to 40% more than the current ambient level. You can use the diffuser with water alone to have more humidifying moist air effects.

7. Removes Foul OdorsThe diffuser used with your favorite essential oil will remove last night’s fishy odor, smoky smells from tobacco products, and any other offensive or stale smells. Your area will smell fresh in no time.

9. No WasteMost oil diffusers have an automatic shut off feature. This permits no waste of your essential oils in that you used them for their purpose and the unit has now shut down. If you do not want to use the full reservoir, shut the unit off and the oils will be there for the next time you turn it on. The oils do not just evaporate into thin air. They are either consumed or waiting to be consumed.

Types of Essential Oil Diffusers

There are several types of diffusers available in the marketplace. Here, we have tried to categorize them to their specific functions. The commonly available types of aromatherapy diffusers are: Nebulizer, Ultrasonic, Evaporative, and Heat.

1. Nebulizer Diffusers

Nebulizer Essential Oil Diffusers

These diffusers are considered the most powerful. They are cold-oil diffusers that disperse pure essential oils by breaking them into tiny molecules. Later these airborne molecules are misted out to create a fragrant atmosphere. The Nebulizer aroma diffusers are ranked higher due to their therapeutic qualities. Since this type of unit does not require adding water, a heavy concentration of aromatic oil is diffused into the atmosphere.


These diffusers use 100% pure essential oils making them more health-friendly. They also have a built-in timer that keeps you informed. No light system is provided with the Nebulizer diffusers.


Nebulizer aroma diffusers are considerably noisy and that can be a turn off for many. It is more expensive and that can be considered a negative to some users. These diffusers scatter larger quantities of oil at one time, consequently they need refills more often, and that can prove costly for many buyers. To control the extra emittance of oil, Nebulizers are now provided with a built-in timer with settings.

2. 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 Ultrasonic diffusers due to the mild concentration of oil.


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.


Since water is added with essential oils in the Ultrasonic diffusers, these are not as efficient in their healing power as Nebulizers. Sometimes, these wellness devices come with a light setting that cannot be turned off. You need to keep it clean and avoid using citrus essential oils in these diffusers.

3. Evaporative Diffusers

Evaporative Essential Oil Diffusers

These basic aromatherapy diffusers scatter essential oils with a fan blowing method with an attached filter. Its evaporating functioning style has given it the name Evaporative Diffusers.


This type of aromatherapy diffuser works perfectly in diffusing fragrance in a smaller area. Another benefit of buying evaporative aromatherapy diffusers is their relatively low cost. These diffusers are easy to carry and come in pleasing designs.


Evaporative diffusers do not disperse the complete blend of essential oils at one time. They tend to portion out the oils. Lighter components are evaporated quicker than heavier components. This apportioning of the components (oils/water) cuts down on the overall therapeutic value of the essential oils. Another drawback of these diffusers is that they have shorter running times.

4. Heat Diffusers

Heat Essential Oil Diffusers

This is also a basic oil diffuser, but instead of evaporating essential oils with the help of an air fan, it uses heat for diffusion. Heat diffusers also create a lovely fragrance inside a closed area.


These are considerably the least expensive of all the aroma oil diffusers readily available to purchase. Most heat diffusers are so small that you can keep them in your vanity kit or purse. They indeed effectively aromatize a specified area.


Since heated oil diffusers also function by evaporating essential oils, they also portion out the components of essential oils. It affects both the healing benefits for oil and the intensity of the fragrance. Some of these diffusers use high levels of heat to produce an extra strong aroma that can change the chemical bonding of the essential oils. Therefore, a diffuser that uses very low levels of heat is considered better.

All 4 Diffuser Types Compared and Reviewed

To know the most efficient category of aromatherapy diffusers, we compared all of the differences regarding the aspects of aroma diffusion, therapeutic value, longevity, and price.

Dispersal of Aroma

Nebulizing diffusers distribute the essential oil by breaking them into smaller molecules allowing it to diffuse fragrance in a shorter time in a larger area. Ultrasonic diffusers also diffuse oil similarly and they equally aromatize an area effectively while evaporative and heat diffusers work well in scattering the fragrance in a smaller area.

Therapeutic Value

Since the Nebulizing diffuser is a cold aroma-dispersing device, it uses the purest form of essential oils. It ranks higher than all other aromatherapy diffusers with heating. The Ultrasonic diffuser is second best while heat and evaporative diffusers are not considered the best for aroma healing because essential oils work best when used cold.


Ultrasonic diffusers are the winner when it comes to running time. These diffusers use a blend of water and a few drops of essential oil. Their higher capacity helps them in diffusing aroma for hours without any breaks in time. Nebulizing diffusers disperse a greater amount of essential oil at one time and might need to be refilled more often. Similarly, evaporative and heat diffusers need to be refilled more quickly.


When it comes to price, heat diffusers are the clear winner, followed respectively by evaporative and ultrasonic diffusers. Nebulizing diffusers are the costliest of all.

So, Which One is Best?

After weighing all criteria of aromatherapy diffusers, ultrasonic diffusers are the best. Nebulizing diffusers are second to the Ultrasonic one but the biggest drawback is the cost. Low longevity, greater energy consumption, and the irritating sound made it a disadvantage.
