In fact, it is more suitable to use aromatherapy humidifier in the south. Although it is humid in the south, you still need aromatherapy humidifier to relieve your worries if you often sit in the air-conditioned room. The air in the air-conditioned room is not circulating and breeds bacteria. At the same time, your skin will be dry and uncomfortable if you stay in the air-conditioned room for a long time The aromatherapy humidifier uses advanced atomization module and air duct design, coupled with ultrasonic vibration technology, so that each aromatherapy humidifier can produce water mist with one fog volume, high consistency and lightness, so as to ensure that the water mist particles are fine and uniform and stay in the air for a long time, so that the human body can better and fully absorb each essential oil molecule. The ultrasonic vibration technology adopted by the aromatherapy humidifier can atomize water molecules to the nano level, and effectively disperse essential oils into the air. Most of them have been absorbed or volatilized by the human body and will not stay in the air for a long time! Therefore, after knowing the principle of the aromatherapy humidifier, you can have the courage to bathe in the fragrant air.
