FAQ
Questions before you start your scent ritual?
Find quick answers about JCLOUD diffusers, oils, refills, shipping, warranty and everyday use.
Before You Buy
Start with the room, then choose your diffuser and oil.
JCLOUD is designed as a scenting system. Choose the machine based on room size, the oil based on atmosphere, and the refill size based on your usage routine.
Which JCLOUD diffuser should I choose?
Choose a compact diffuser such as AP-353 for bedrooms, bathrooms, hallways and smaller everyday spaces. Choose a stronger diffuser such as JC002 for larger rooms, open spaces and whole-home scenting routines.
What is the difference between waterless diffusers and ordinary ultrasonic diffusers?
JCLOUD waterless diffusers are designed to disperse fragrance oil without adding water or heat. Ordinary ultrasonic diffusers usually mix oil with water, which can create a lighter scent impression.
Should I buy oil with my diffuser?
Yes. Your diffuser needs compatible diffuser oil to create the scent experience. For a first full-size scent routine, 100ML oils are the clearest starting point.
Should I start with 100ML or 500ML oil?
Choose 100ML if you are starting with a new scent. Choose 500ML after you know your favorite scent and want a long-use refill format.
Are discovery sets the same as starter kits?
No. Discovery sets are for trying different scent profiles or gifting. A true starter kit should include a diffuser plus a full-size 100ML or 500ML oil.
Diffusers
Questions about JCLOUD machines.
Use these answers to understand basic setup, daily operation and which diffuser fits your space.
Do JCLOUD waterless diffusers need water?
No. Waterless diffusers are designed to work without adding water. Add compatible diffuser oil as directed by your machine instructions.
Do JCLOUD diffusers use heat?
No. JCLOUD focuses on waterless cold-air diffusion, so the scenting process does not rely on heating the oil.
Where should I place my diffuser?
Place your diffuser in an open area with good airflow. Avoid blocking the mist outlet or placing objects directly above the diffuser.
How strong should I set the scent intensity?
Start with a lower setting, allow the scent to develop in the room, then adjust based on room size, airflow and personal preference.
Can I use one diffuser for my whole home?
It depends on your diffuser model, room layout, airflow and usage settings. Larger spaces usually need a stronger diffuser than compact bedrooms or bathrooms.
Oils & Refills
Questions about scents, sizes and refill routines.
JCLOUD oil shopping should feel simple: choose 100ML for a first full-size scent, 500ML for long-use refill routines, and discovery sets for exploring scent profiles.
Which scent should I choose first?
Choose White Tea for a clean and soft atmosphere, Luminous White Dew for a fresh and bright impression, or Royal Serenity for a warmer hotel-inspired feeling.
What is 100ML oil best for?
100ML oils are best for your first full-size JCLOUD scent routine or for choosing a new daily scent for your diffuser.
What is 500ML oil best for?
500ML oils are best for customers who already use their diffuser consistently and want a longer-use refill format.
Can I switch between different scents?
Yes. Clean the bottle, tube or atomizer area according to your diffuser instructions before switching oils to help avoid scent mixing.
Can I use non-JCLOUD oils?
Use oils that are compatible with your diffuser. For the best experience, pair JCLOUD diffusers with compatible JCLOUD diffuser oils and refills.
