Pleated Filter Cartridge: A Complete Guide for Industrial Filtration The most advanced and surface filters are designed to control sediments, particles, and contaminants from passing through the filter media. The pleated structure, particularly increasing surface area, allows the filter to catch and hold a large amount of impurities in comparison to many conventional filters, like string-wound or melt-blown cartridges. They are known for delivering both minor and absolute efficiency. PP pleated filter cartridges are widely used in industries in which high purity and accuracy are important, including industries like pharmaceutical production, food and beverage processing, electronics manufacturing, and the production of pure water.
