  • Our home is a tranquil, spa-like oasis. We have four children and two dogs.

With the right blend of fragrances (and our eyes closed), could we not recreate that captivating scent, and the emotions that go with it?

While scented candles are an option, I was attracted to the idea that essential oils could be diffused. Our house would smell amazing, and we could all benefit from the aromatherapy. Maybe there would be some humidifying bonus.

I tried a lot of diffusers in my quest to find one that actually works. I interviewed a variety of aromatherapy experts as well as representatives of various diffuser companies.

This is what I discovered during my deep dive into diffusing. It also includes my recommendations for the best diffusers.

What is a diffuser?

A diffuser is a device which breaks down essential oils or synthetic oils into small molecules that can be evenly distributed into the air. This creates a beautiful aroma and other effects.

Essential oils have many benefits, including calming, soothing and invigorating effects, as well as stress-relieving properties. There are also personal associations.

“Different smells can elicit different emotions as our limbic system (seat for emotion and memory) is directly in communication with olfaction,” Kara Montgomery, a member of the Bloomy Lotus team, said.

Here’s an interesting fact: Our sense of smell can trigger emotions, even before our nose identifies the scent. Our sense of smell is so powerful. It’s more than the smell, it’s how we perceive it.

Different types of diffusers

There are many options available in the world of diffusers. However, most can be divided into three main categories.

Ultrasonic diffusers

These devices are made up of an oscillating plate, which vibrates to produce and release cool, odorless mist.

Trevor T’uytemken Ellestad (education and communications manager, in house herbalist and aromatherapist at Saje Natural Wellness) describes it as “like the mist around a waterfall.”

“When essential oils are added to water, the vibration breaks down the essential oil into smaller particles which are released into the mist.”

Nebulizing diffusers

These diffusers do not use heat or water. Elisabeth Lemieux, ECO, explains that these diffusers “atomize essential oils into fine particles.” Modern Essentials.

“Nebulizers use more essential oils for a shorter time. She says that the essential oils in the air are much higher.

Passive diffusers

This diffuser does not use heat or water and is also non-powerful. It does not require any cords, outlets or batteries.

Bella Martinez, Edens Garden’s lead aromatherapist, says that passive diffusers include reed diffusers and gentle oil warmers. Diffusers that use porous clay to naturally emit essential oils in the air are examples of passive diffusers.


Ultrasonic and Nebulizing diffusers come with many bells and whistles. These include ambient lighting, automatic shutoffs as well as scent intensity and interval settings.

Diffusers are safer than candles because they have these features. Diffusers can be used to create a relaxing atmosphere or to bring in the aromas when you return to your home.

Diffusers don’t only have to be about the scent. Sara Panton, co-founder of Vitruvi, says that a diffuser can be used as decor to tie together a space.

Panton states that diffusers with specific textures or colors can enhance the space’s mood, which in turn makes it feel and look great.
