The Hangzhou Teo Enviro-Tech Co., Ltd. humidifier series utilizes biological wet film technology for humidification. It takes advantage of water's evaporative property, continuously transporting water to the top of the wet film via a pump and distributor. Under gravity, the water flows back to the main water tank, forming a circulation. When dry air passes through the wet film, it comes into full contact with it, causing the water to evaporate due to the humidity in the air, thereby increasing the humidity to achieve the humidification goal.
