A PP pleated filter cartridge is a depth filtration device made using polypropylene membrane or melt-blown media that has been pleated to increase the surface area. These cartridges are widely used for filtering particles and contaminants from liquids, especially in industries requiring high purity and consistent filtration.
Polypropylene (PP) is chemically resistant, thermally stable, and inert, making it an ideal material for critical filtration tasks in water treatment, food processing, and pharmaceutical manufacturing.
Pleating the filter media significantly enhances the filtration area compared to traditional cylindrical filters, enabling longer operational life and higher flow rates. The cartridges are available in a range of micron ratings, from ultra-fine 0.1 micron up to 50 microns, and are suitable for pre-filtration, final filtration, or as part of a multi-stage filtration system.
PP pleated filter cartridges are available in various lengths (10″, 20″, 30″, 40″) and end cap configurations (DOE, 222, 226, Fin, Flat, etc.), making them compatible with a wide range of standard housings.

PP (Polypropylene) Pleated Filter Cartridges Technical Guide
Q1: What is the difference between pleated and melt-blown PP filters?
A1: Pleated PP filters have a larger surface area due to their pleated design, providing higher dirt-holding capacity and longer life than melt-blown filters. They are ideal for high flow and low pressure drop applications.
Q2: How often should I replace a PP pleated filter cartridge?
A2: It depends on your application, but generally every 3 to 6 months or when pressure drop exceeds recommended levels.
Q3: Are these filters compatible with all filter housings?
A3: Yes, we offer various end cap types (DOE, 222/Flat, 226/Fin) to fit most industry-standard housings.
Q4: Can I get custom branding on the filters?
A4: Absolutely. We support OEM/private label customization, including packaging, logo printing, and product specifications.
Q5: What is your MOQ and lead time?
A5: Our MOQ is typically 100 pcs, and standard orders ship in 3–5 days. For custom orders, delivery is 7–10 days.
