When you're choosing a glass diffuser, one number matters more than almost any other: the tank size. It quietly decides how long your diffuser runs, how often you refill it, and even where it fits best in your home. So which one is right for you — a compact 120 ml, or a full-night 230 ml? Here's how to decide.
The quick comparison
| Bellflower (120 ml) | Golden Branch (230 ml) | |
|---|---|---|
| Continuous mist | up to 4 hours | up to 8 hours |
| Intermittent mist | up to 8 hours | up to 18 hours |
| Best for | Nightstands, desks, small rooms | Full nights, larger bedrooms |
| Material | Hand-blown glass shade | Frosted glass + solid wood base |
| Light modes | 4 (including candlelight) | 3 soft modes |
Choose 120 ml if…
The Bellflower Glass Diffuser holds 120 ml and runs up to 4 hours continuous, or 8 hours intermittent. That's the right size when you want:
- An evening companion. Perfect for a few hours of reading, winding down, or a calm dinner — then it's done.
- A smaller footprint. It sits neatly on a nightstand, a desk corner, or a bathroom shelf without dominating the space.
- Softer lighting choices. Four light modes including a warm candlelight glow make it a favorite for cozy evenings.
If you tend to run a diffuser for part of the evening rather than all night, 120 ml is often the smarter, less wasteful choice.
Choose 230 ml if…
The Golden Branch Glass Diffuser holds 230 ml and runs up to 8 hours continuous, or up to 18 hours intermittent. Reach for this size when you want:
- All-night coverage. One fill before bed carries you from lights-out to morning — no midnight refills.
- A larger room. More mist output suits a bigger bedroom or an open living space.
- Fewer refills overall. If topping up a small tank every few hours annoys you, the bigger tank simply asks less of you.
What if you're still unsure?
Ask yourself one question: do you mostly want fragrance for the evening, or through the whole night?
- Evenings and desktops → 120 ml Bellflower
- Full nights and larger rooms → 230 ml Golden Branch
Both are hand-blown glass rather than molded plastic, both run on whisper-quiet ultrasonic atomization, and both include waterless auto shut-off — so the only real decision is how long you want the mist to last.
The bottom line
Tank size isn't just a spec — it's how you'll actually live with your diffuser. Match it to your routine, and you'll refill less, waste less, and enjoy it more. Browse the Bellflower for cozy evenings, or the Golden Branch for full-night calm.
