What is the working principle of Air Filter ?

Polypropylene (PP) Cartridge Filters are widely used in water treatment, air purification, and chemical filtration. Made from thermally welded polypropylene, they effectively remove particles in liquids, such as in pharmaceuticals and beverages, while extending the lifespan of sterilization filters. These filters use physical, fiber, and depth filtration mechanisms to capture larger and smaller impurities, with micron-level filtration precision (as fine as 0.1μm). PP's chemical inertness prevents contamination, making it suitable for varying pH levels. With advantages like high filtration efficiency, long lifespan, chemical resistance, low cost, and ease of maintenance, they are commonly used in water treatment, food and beverage industries, pharmaceuticals, and air filtration systems.
