Questions about this diffuser
How big a room can the 4L tank handle?
The 4-litre tank is sized for whole-room use — living rooms and larger bedrooms — rather than a single desk. Turn the mist up to fill a dry room, or ease it down for a gentler background scent.
How long does one fill last?
That's the point of the 4-litre tank: it runs for hours on a single fill, so you're not topping it up through the day. Actual run time depends on how high you set the mist output.
How do I refill it — do I have to tip it over?
No. It's a top-fill design, so you just lift the lid and pour water straight in. Add five to ten drops of fragrance oil and you're set.
Can I leave it running overnight?
Yes. Use the sleep mode and timer to run it while you fall asleep, and it shuts off automatically when the tank runs dry — cool mist, no heat, whisper-quiet.
