The humidifier is powered by a USB cable, with no battery-in.
Please use mineral water or clean tap water, it is not recommended to use distilled water or pure water to avoid the mist port residual water droplets affecting the spray.
Do not add essential oils directly without water; add a maximum of 1~2 drops of essential oil each time; the essential oil composition may affect the life of the humidifier or clog the atomizing piece.
Before use, make sure both ends of the cotton filter are soaked to fully absorb water (about 5-10 minutes at the first time or long-term storage).
It is recommended to replace the cotton filter in 1~2 months.
