Home » Filter Cartridges

Polypropylene spun filter cartridges are core components in industrial water treatment, chemical liquid filtration, and household water purification systems.

The “loose outer, dense inner” pore structure ensures deep-bed filtration. It traps large particles on the surface and smaller particles deep within, which significantly prevents premature clogging and dramatically boosts dirt-holding capacity.

The unique fibrous, plush surface finish combined with randomly interwoven microfibers dramatically reduces fluid resistance. It maintains an exceptionally low operating pressure drop while ensuring a particle removal efficiency of up to 98%.

Constructed from 100% virgin, food-grade polypropylene. It is non-toxic, odorless, and completely free of media migration or fiber shedding, guaranteeing zero secondary pollution and full compliance with strict sanitary standards.

By precisely controlling fiber thickness and density distribution, the coarser inner fibers form a highly rigid matrix. This provides superior structural integrity, allowing the cartridge to withstand high differential pressures without requiring an inner support core.

Typical Applications

Acts as an essential guard filter to protect expensive Reverse Osmosis (RO), Ultrafiltration (UF), and Nanofiltration (NF) membranes from fouling.

Ideal for residential, commercial, and municipal water purification systems, water softeners, and point-of-use (POU) drinking water filters.

Widely used for cooling water, process water, and wastewater treatment in power generation, electroplating, metallurgy, and petrochemical industries.

Clarification and pre-filtration for bottled water, beverages, beer, wine, syrups, liquid sugar, and edible oils.

High-efficiency pre-filtration for Ultra-Pure Water (UPW) loops, chemical reagents, acids, alkalis, and photoresist developing solutions.

Filtration of organic solvents, inks, paints, coatings, plating baths, and various chemical fluids.
