PATENTED OIL FLOW SYSTEM: 12 Hours of Consistent Scent & Aromatherapy with OneFill technology. With one single fill (around 1.5ml / 30 to 40 drops), the scent will last 11 to 15 hours in low mode and 6 to 10 hours in high mode. With other diffusers, oil must be added constantly due to diminishing scent
WHISPER QUIET: Designed on the base of the principle of hydrokinetics to operate below 30dB which will not affect your sleep or your work
AUTO SHUT OFF FUNCTION: Automatically shuts off in 5 seconds after running out of water as a safety feature. You have the option to set timer (1Hr/4Hrs/8Hrs), and the diffuser will turn off accordingly
