Our waterless ultrasonic diffusers use advanced atomization technology that differs from traditional water-based models. During normal operation, microscopic essential oil particles naturally adhere to the internal components over time.

Understanding the Issue:

As essential oils evaporate and atomize, residue gradually builds up on the inner walls and atomizing disc. This accumulation can restrict airflow and reduce mist output, but it doesn't indicate a malfunction—it's a normal part of regular use that requires periodic maintenance.

What to Do:

If you notice reduced mist production or weakened fragrance after extended use, the diffuser likely needs cleaning rather than repair. A thorough cleaning will restore full functionality by removing oil buildup from the internal components.

Prevention:

• Clean your diffuser every 2-3 weeks with regular use
• Rotate between different essential oils to prevent heavy buildup
• Use high-quality, pure essential oils without additives

Regular deep cleaning maintains optimal performance. If your diffuser stops producing mist, follow this cleaning protocol:

Deep Cleaning Steps:

1. Empty any remaining essential oil or water from the reservoir
2. Fill the tank with isopropyl alcohol (70% or higher)
3. Run the diffuser for 10 minutes, gently pressing the mist outlet periodically to help dislodge buildup
4. Remove the atomizing disc and shake it several times to release trapped residue
5. Pour out the alcohol and rinse thoroughly with clean water
6. Allow all components to air dry completely before refilling with fresh water and essential oils

Maintenance Tips:

• Perform this deep clean every 2-3 weeks with regular use
• For daily maintenance, simply wipe the reservoir with a damp cloth
• Always use distilled water to minimize mineral deposits
