Short answer: Choose a 500ML diffuser oil refill when you already know the scent you like and use your diffuser regularly. 100ML oils are best for first-time scent testing. 500ML refills are better for larger spaces, frequent routines, commercial machines, and long-term refill planning.
Why 500ML refills matter
The diffuser creates coverage, but the oil creates the atmosphere. Once you find the scent that works for your home, office, studio, or commercial space, a larger refill makes the routine easier to maintain.
When to start with 100ML
Start with 100ML if you are choosing your first scent, testing a new fragrance profile, or using a diffuser in a smaller space. It is also useful when comparing several hotel-inspired scents.
When to move to 500ML
Move to 500ML diffuser oil refills when you use your diffuser regularly, scent a larger space, or want fewer small-bottle replacements.
