Regarding water filter cartridges, there are two manufacturing processes: folding and winding. Users can select appropriate water filter cartridge products based on factors such as size, micron rating, and materials.
Folded Filter Cartridge
The folded filter cartridge employs various materials like polypropylene as the filtration medium. Through the folding technique, its filtration area is expanded. It has a filtration accuracy ranging from 0.1 - 60 μm, enabling it to precisely capture minute impurities with an interception rate exceeding 90%.
Materials: Polypropylene, hydrophobic polytetrafluoroethylene, hydrophilic polytetrafluoroethylene, etc.
Applications: Industries with high water quality requirements such as reverse osmosis water systems, deionized water, and the pharmaceutical industry.


Wound Filter Cartridge
The wound filter cartridge is made by winding fibers such as polypropylene filaments around a framework, presenting a structure that is loose on the outside and dense on the inside. Generally, its filtration accuracy is between 1 - 100 μm, effectively filtering out large particles such as suspended solids and rust.
Materials: Absorbent cotton, polypropylene filaments, thread, glass fibers, etc.
Applications: Preliminary filtration in the electronics, petroleum and other industries.


In summary, there are certain differences between folded water filter cartridges and wound water filter cartridges in terms of structure, accuracy, application scenarios, etc. Users can make a choice based on factors such as water quality requirements, filtration equipment, and usage environment.
