500mL provides five times the oil volume of 100mL. Compare the current price per 100mL and applicable offers; a larger size is not automatically cheaper.

Follow your machine’s fill limit and cleaning instructions. Do not pour the full 500mL bottle into a smaller reservoir or assume this retail bottle screws directly into the machine.

FAQ
Royal Serenity refill questions
What does Royal Serenity smell like?
A lemon, peach and mint opening leads into rose, violet, lily and jasmine, followed by musk, amber and woods. Choose it for a warmer floral-and-amber direction rather than White Tea’s softer tea-led character or Luminous White Dew’s bright citrus-and-basil opening.
Is this an official hotel product or a pure botanical essential oil?
Royal Serenity is sold as a JCLOUD home-fragrance diffuser oil refill. Hotel inspiration does not mean hotel endorsement or an identical formula. The fragrance name and scent notes do not establish botanical purity, ingredient certifications, suitability for skin or food, or universal safety; follow the product label.
Can I use it in any diffuser or humidifier?
Use only in a device approved for this type of diffuser oil. For compatible JCLOUD waterless models, do not add water or carrier oil. Compatibility with every ultrasonic humidifier, reed diffuser or other device is not implied. Do not apply oil directly to HVAC filters.
How long will a 500mL bottle last?
There is no fixed number of months. Consumption depends on the diffuser model, intensity and operating schedule. Begin at a low setting, observe your usage and plan refills accordingly. A larger retail bottle does not change the machine’s reservoir capacity.
How should I refill or change fragrances?
Follow the model’s fill limit and cleaning instructions. Clean the bottle, tube or atomizer as instructed before changing scents, and store remaining oil in its original closed bottle according to the label. Do not assume the retail refill bottle attaches directly to your diffuser.
