Zenith Ceramic Aroma Diffuser

Yes, you can use thicker essential oils in this diffuser, but you should add a few drops to water first rather than applying them directly. The ultrasonic technology is strong enough to disperse the oils, though regular cleaning is necessary to prevent the thick resin from clogging the ceramic nozzle.

The integrated LED lighting offers multiple modes, including a candle-flicker effect, a steady color, and a complete off setting. You can run the diffuser in your bedroom at night without the light disrupting your sleep while still enjoying the aromatherapy benefits.

You should unplug the unit and wipe the inside water reservoir with a damp cloth or cotton swab dipped in a mild soap solution. Because the exterior is crafted from high-quality ceramic, avoid fully submerging the entire diffuser in water to protect the internal electronics.

On the highest mist setting, the diffuser provides continuous gentle diffusion for several hours before needing a refill. Many models in this category also feature an automatic shut-off safety switch that triggers when the water level gets low.
