Frequently Asked Questions

AI
Ultrasonic diffusers use high-frequency vibrations to create a cool mist, often doubling as humidifiers. Ceramic or stone diffusers rely on passive evaporation, releasing scent slowly without water or electricity, making them quieter but less potent for large spaces.
To prevent mold and maintain oil quality, clean your diffuser at least once a week. If you use oils daily, a quick rinse with water and mild soap after each refill is recommended. Deep clean monthly with white vinegar to remove oil buildup.
Most modern diffusers feature auto-shutoff safety switches that turn the unit off when the water tank is empty, making them generally safe for overnight use. However, it is best to use them in well-ventilated areas and follow manufacturer guidelines for continuous operation.
