According to the national standard GB / T23332-2018, humidifiers are commonly classified into ultrasonic, evaporative, and electric heating types. Among them, the ultrasonic type has a large humidification capacity and rapid humidification, but there is pollution brought into the water source, such as scale and bacteria, and the white mist phenomenon is obvious, etc., which poses certain health risks; the electric heating type requires heating, so the energy consumption is relatively high; and the evaporative type is increasingly attracting attention for its quietness, no white mist, low energy consumption, and high safety factor, and is often called wet film humidification or pure humidification.

[0003] In order to achieve a good wet film humidification effect, the humidification filters of existing commercially available civilian humidifiers are mostly made of highly absorbent wood pulp paper, spunlace cotton, 3D mesh cotton and other materials. However, due to material and process reasons, the humidification filters often have shortcomings such as softening and deformation when exposed to water.

[0004] Currently, the humidification filter elements of commercially available civilian humidifiers often use cylindrical humidification filter screens, which are mostly made by punching and stacking humidification materials to obtain square sheets of a certain thickness, and then cutting them into a circle to obtain a cylindrical humidification screen. The processing steps are complicated, and the cutting process has a high degree of waste of raw materials. Summary of the invention
