Ultrasonic diffuser — a versatile choice
An ultrasonic diffuser disperses oil as a fine mist while lightly humidifying the room's air. It's the most commonly chosen option for home use — quiet, usually equipped with a timer and different modes, making it easy to match to the time of day.
Wood-finish diffuser
Wood-finish diffusers combine function with aesthetics — they look great as part of a room's decor. They typically run quieter and more subtly than ultrasonic models, making them a good choice for smaller rooms or a desk.
Car diffuser
A compact diffuser that plugs into a car's cigarette lighter or USB port lets you enjoy your favorite scent (Peppermint on a long drive, for instance) without opening the bottle or applying oil directly to your skin.
What to consider when choosing
- Water tank capacity — larger means longer run time between refills.
- Noise level — especially important in a bedroom or office.
- Auto shut-off once the water runs out — improves safety.
- Room size — larger spaces need a stronger diffuser.
