A PP (Polypropylene) pleated filter cartridge is a depth-type filter made from 100% polypropylene media. It is designed to remove particulate contaminants from liquids in various industrial processes. The pleated structure significantly increases the surface area compared to traditional melt-blown filters, allowing for higher dirt holding capacity and longer service life.
These cartridges are manufactured without adhesives, binders, or surfactants, ensuring chemical compatibility and purity. They are widely used in applications requiring high cleanliness, such as reverse osmosis pre-filtration, pharmaceutical manufacturing, beverage production, and electronics.
PP pleated filter cartridges are available in various lengths and micron ratings. They are compatible with standard filter housings, making them easy to install and replace. Whether in municipal water plants or industrial cooling systems, they play a vital role in protecting downstream equipment and ensuring process integrity.
High Dirt Holding Capacity: Pleated design increases surface area, extending service life.
Wide Chemical Compatibility: 100% polypropylene construction resists most acids, alkalis, and solvents.
Thermally Bonded Structure: No adhesives or binders, ensuring pure and clean filtration.
Broad Micron Range: Available in 0.1μm, 0.22μm, 0.45μm, 1μm, 5μm, 10μm, 20μm, 50μm.
Compatibility: Fits standard DOE, 222/flat, and 226/fin filter housings.
Consistent Flow Rate: Uniform media distribution ensures stable flow and minimal pressure drop.
FDA-Compliant Materials: Safe for use in food, beverage, and pharmaceutical industries.
PP pleated filter cartridges are widely used in diverse industries due to their versatility and chemical resistance. Typical applications include:
Water Treatment: RO pre-filtration, DI water systems, and municipal water purification.
Food & Beverage: Filtration of beer, wine, mineral water, and soft drinks.
Pharmaceutical: Filtration of bulk chemicals, APIs, and injectable water.
Electronics & Semiconductors: Process water and cleaning solution filtration.

Q1: What is the lifespan of a PP pleated filter cartridge?
A1: Lifespan varies depending on the application, feed water quality, and operating conditions. Typically, it ranges from 3 to 6 months. Regular pressure drop monitoring helps determine when replacement is needed.
Q2: Can PP pleated filters be reused after cleaning?
A2: These filters are primarily designed for single-use. Although physical cleaning may be attempted, it may not fully restore performance. For critical applications, replacement is recommended.
Q3: What’s the difference between melt-blown and pleated filters?
A3: Melt-blown filters have a smaller surface area and lower dirt holding capacity. Pleated filters offer more surface area and a longer service life, making them more cost-effective over time.
Q4: Are PP pleated cartridges compatible with all housings?
A4: Yes, we offer various end cap styles including DOE, 222, and 226 to match standard housings. Custom options are also available.
Q5: Do you offer samples for testing?
