Frequently Asked Questions - AD90G Stirling
How do I clean my Stirling AD90G aroma diffuser?
To maintain optimal performance, unplug the device and empty any remaining water. Use a soft, damp cloth and a mild detergent or white vinegar to wipe the inner tank. Avoid submerging the base in water. Let it dry completely before the next use.
Which essential oils can I use?
The AD90G works with most 100% pure essential oils. Please avoid synthetic or thick oils as they may damage the ultrasonic membrane. Add just a few drops per tank fill.
What is the correct water level?
Fill the tank up to the maximum water line indicator. Typically, this is about 150 ml. Do not overfill to ensure proper mist output.
Why is the mist output weak?
A weak mist often indicates mineral buildup or low water level. Clean the transducer with vinegar and ensure the tank is filled to the recommended level.
Can I leave the diffuser on overnight?
Yes, the auto shut-off feature turns the unit off when water runs out. You can also set a timer for 1, 3, or 6 hours for controlled operation.
How often should I clean it?
For daily use, rinse once every 3 days and do a deep clean weekly using water and vinegar to prevent mold and scale.
Is it safe for pets and children?
The device uses cool mist, making it safe when placed out of reach. Always supervise the device in rooms with children and don't block the mist outlet.
What should I do if the LED light doesn't turn on?
Check the power adapter connection and ensure the plug is secure. If the light still fails, contact Stirling support for the replacement of the AC adapter.
Can I use the diffuser to humidify a dry room?
While it provides some moisture, it is primarily an aromatherapy diffuser. For best results, use it in small to medium-sized rooms (about 25 m²).
Where can I purchase replacement parts?
Visit the Stirling official website or contact their customer service. Replacement AC adapters and internal ultrasonic discs are commonly available.
