An oil diffuser is 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 meant to support sleep.1 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.

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 ambiance. “It’s well known that scent is associated strongly with memory,” says 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.”

Ideo Rama9 Asoke organized an activity to make incense with a diffuser with customers participating in the event on February 11, 2023.
