What is an oil diffuser?

The most effective wellness routines are those that fit easily into your daily life. Think of oil diffusers as a low-effort entrée into self-care, as they bring elements of wellness into your home, transforming your space into a tranquil nest where you can (sometimes literally) breathe easier. These aromatic room fresheners require minimal effort for you to recharge your decor and up your self-care game in the process. Proceed with caution, though—diffusing essential oils can be super powerful, and not everyone should do it. Here, everything you need to know about oil diffusers.

What Is an Oil Diffuser?

To put it simply, an oil diffuser is essentially a device that breaks essential oils down into smaller molecules, dispersing them into the air for a pleasant or calming effect—depending on the oil that's been put into the diffuser. Different essential oils have different claims, for example, lavender is supposed to support sleep. The diffuser's job is to evenly disperse the particles at a comfortable concentration that's easy to breathe and doesn't overbear the room.

What It's Used For?


Plain and simple, a diffuser is used to fill the air in a room with tiny, breathable particles of beneficial essential oils—giving the room a calmer, more pleasant-smelling ambience.

“It's well known that scent is associated strongly with memory,” says wellness expert Esme Benjamin. “When I diffuse lemongrass oil it reminds me of Thailand, my happy place, and I instantly feel a vacation level chill come over me. Oils just set a tone for your space and the activity you're performing that day.”

Who doesn’t love a wellness tip that offers immediate benefits with minimal effort? “Using a diffuser gives you an instant effect because the essential oils will get to work straight away,” says Jo Kellett, a member of the International Federation of Professional Aromatherapists and the in-house aromatherapist for Tisserand Aromatherapy. 

Plus, “Diffusing oil as a daily ritual can help encourage good habits associated with particular scents,” adds Benjamin. “For example, using lavender oil when I get home from work has become a signal it's time to start winding down, get off technology, run a bath, read a book, and so on.”
