The wet film humidifier utilizes the evaporative nature of water. Water is continuously delivered to the top of the wet film via a water pump and distributor. The water is evenly sprayed onto the top of the wet film, and the sprayer ensures that the water is evenly distributed across the wet film material. As the water percolates downward through the wet film material, it moistens all the layers within the film and is absorbed by the material, forming a uniform water film. When dry air passes through the wet film, it comes into full contact with the large surface area of the wet film. The sensible heat in the air causes the water to vaporize, thereby increasing the humidity and achieving the purpose of humidification.

Clean and noiseless. It has a washing and filtering effect on the air. It has a humidifying and cooling effect. It humidifies with cleanliness and constant enthalpy, without producing "white powder" phenomena.
