I’m glad you’re interested in the best ultrasonic essential oil diffusers.

A diffuser like one of these is an easy, inexpensive way to do aromatherapy.

But there are other essential oil diffuser benefits.

An ultrasonic diffuser will fragrance your home to make it more comfortable and welcoming.

It can also reduce germs during cold and flu season.

That’s right. Science shows that sufficient humidity gets rid of the flu virus (1).

But how do you know which is the best ultrasonic essential oil diffuser?

How to Choose the Best Ultrasonic Diffuser

To avoid disappointment after purchasing a diffuser, make sure you consider these features first.

• Coverage area – how far can the vapor reach? Most diffusers specify the square footage.
• Convenience – is it easy to refill and clean?
• Controls – does it have a timer, adjustable mist, and a way to manage the mood light?

After you find a diffuser that matches your needs with regards to those points, then think about your décor. There are so many essential oil diffusers on the market that you are sure to find exactly what you want.

For example, consult my article about the best essential oil diffuser for a large space. You’ll see that there are several different types and styles, including smart diffusers.

How Do Ultrasonic Diffusers Work?

Ultrasonic diffusers and cool mist humidifiers are very similar, but you can’t use a regular humidifier to disperse essential oil. You’ll gum up the works if you try.

Ultrasonic models are very quiet. They emit a visible mist that contains water vapor and tiny particles of essential oil.

Inside, there is a ceramic disk that vibrates at ultrasonic frequencies. It breaks up the liquid into tiny droplets that emerge into the air (2).

If you use distilled or filtered water and clean the tank regularly, you should be able to enjoy years of reliable service. [Read more…]

How do you determine what size diffuser you need?

Which kind of diffuser is best-suited to large spaces?

These are the questions I hear from people shopping for the best essential oil diffusers for large rooms.

Let’s look at the answers now.

What Is the Best Diffuser for a Large Room?

To cover a large room, you need a diffuser with sufficient output.

Passive diffusers (like reed diffusers) won’t be strong enough.

But the size of the tank isn’t as important as how much mist it produces.

A compact nebulizing diffuser may be more powerful than a large ultrasonic humidifier.

That’s because a nebulizing diffuser puts out pure essential oil that’s undiluted by water vapor. The aroma spreads throughout a large area.

Meanwhile, an ultrasonic diffuser emits water vapor that’s fragranced by essential oils. It adds moisture, but not as much scent to the air (1).

In either case, it’s smart to have good ventilation wherever you use a diffuser. As nice as it may smell, essential oil is very concentrated and potent (2). Limit your exposure to no more than an hour at a time, and make sure pets can leave the room.

When you choose a diffuser, look at the specifications for how much square footage it can cover. Compare that to the size of the space where you intend to operate it.

I’ve divided the reviews below into two categories: nebulizing and ultrasonic diffusers. These are the two types that are best for large rooms.

Nebulizing Diffusers for Large Rooms

How do nebulizing diffusers work?

They have a pump inside that sends a stream of high-speed air to atomize essential oil into tiny particles. The particles emerge from the diffuser into the room air (3).

The best nebulizing diffusers can handle thick essential oils like those made from resin. They hum quietly as they run intermittently according to a timed schedule. [Read more…]

The selection of aromatherapy diffusers on the market is frankly overwhelming.

How is a person supposed to know which are the best room diffusers?

This confusion is why I’m going to tell you about the best glass essential oil diffusers.

Some are waterless, also known as nebulizers or atomizers.

Others have a water tank as they are ultrasonic humidifiers.

I’ll point out the differences and similarities to help you find what you want.

What Are the Benefits of Essential Oil Diffusers?

I may be preaching to the choir, but I need to put in a good word.

Diffusers are beneficial for several reasons.

Not only will they fragrance your home, office, or car, but they also promote well-being.

Diffusing essential oils benefits your mind and body.

Aromatherapy can dispel bad moods, reduce stress, help you focus, improve your breathing, and get rid of germs.

But your experience is definitely impacted by the quality of your diffuser.

The best essential oil diffuser on the market is the one that you will use and enjoy.

Therefore, let’s quickly go over the features you’ll want to consider.

Features Found on the Best Glass Oil Diffusers

As you begin to look for a diffuser, think about the questions below:

• Coverage – how far does the aroma reach?
• How long does it run before it needs a refill?
• Is there a timer?
• If there’s a mood light, can you alter the color or turn off the light completely?
• How noisy is the diffuser?
• How easy is it to clean?
