The Hangzhou Teoao Environmental Protection Technology Co., Ltd.'s humidifier series utilizes bio-humidifying film technology. It employs the evaporation of water, continuously transporting water to the top of the humidifying film through a pump and distributor. Under gravity, the water returns to the main water tank, forming a circulation. When dry air passes through the humidifying film, it comes into full contact with the film, causing the water vaporization due to the moisture in the air, thereby increasing humidity to achieve the humidification goal.
