The filter element materials of currently commercially available filter-type air purifiers are mainly made of plastic fiber, fine-mesh metal mesh and swimming pool filter element support non-woven materials, etc., which play a role in filtering larger dust and pollution particles in the indoor air.
The filter material is generally folded into a three-dimensional filter element to increase the filtration area, effectively filter and absorb small particles and bacteria in the air, and extend its service life.
In the traditional and practical molding of wet-process aggregate non-woven fabrics, high-concentration raw pulp needs to be diluted with white water for molding. The white water generated after dehydration during molding will be directly discharged to the sewer and cannot be recycled. At the same time, causing pollution to the environment.
