As a trusted manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been delivering high-quality filtration solutions since 1998. Our 5 Micron Melt Blown String Wound Water Purifier Filter Element (4.5" x 20") is engineered for use in Big Blue style housings, offering reliable sediment removal for residential, commercial, and industrial water systems. With over two decades of experience and an annual export value exceeding US$5 million, we ensure that every cartridge meets rigorous standards for performance and durability.
This filter element combines two proven filtration technologies: melt-blown polypropylene for depth filtration and string winding for enhanced dirt holding capacity. The 5 micron rating effectively traps fine particles such as sand, silt, rust, and scale, protecting downstream equipment and improving water clarity. Designed for standard 4.5" x 20" Big Blue housings, it provides a cost-effective solution with long service life.
Key Features
- Dual Filtration Technology: Melt-blown core provides consistent pore structure, while outer string winding adds mechanical strength and high dirt loading capacity.
- 5 Micron Absolute: Removes 99% of particles larger than 5 microns, including sediment, rust, and sediment.
- Standard Big Blue Size: 4.5" diameter x 20" length, compatible with most 4.5" Big Blue housings (e.g., Pentek, Ametek, etc.).
- High Temperature Resistance: Operates effectively up to 125°F (52°C), suitable for hot water applications.
- Low Pressure Drop: Optimized design ensures minimal flow restriction, maintaining water pressure.
- Food-Grade Materials: Polypropylene components are FDA-compliant and safe for drinking water.
- Customizable Options: Available in different lengths and micron ratings upon request.

Benefits for Your Application: This filter element is ideal for whole-house water filtration systems, pre-filtration for RO systems, irrigation, and industrial process water. Its high dirt-holding capacity reduces replacement frequency, saving you time and money. The 5 micron rating ensures that fine sediments are captured without excessive pressure drop, maintaining consistent water flow.
The string wound construction creates a gradient density that traps larger particles on the outer surface and finer particles deeper inside, maximizing filter life. Additionally, the melt-blown inner layer provides structural integrity and uniform filtration. This combination makes our cartridge suitable for both municipal and well water supplies.
We offer customization options including different lengths (10", 20", 30", 40"), micron ratings (1, 5, 10, 20, 50), and core materials (polypropylene or stainless steel). Contact us for bulk pricing or private labeling services.

Frequently Asked Questions
Q1: How often should I replace this filter element?
A: Replacement frequency depends on water quality and usage. Typically, for average municipal water, replace every 3-6 months. For well water with high sediment, you may need to replace more frequently. Monitor pressure drop – when it increases significantly, it's time to change.
Q2: Is this filter suitable for hot water?
A: Yes, it can handle temperatures up to 125°F (52°C). For continuous hot water applications, ensure your housing is rated accordingly.
Q3: Can I use this cartridge in a standard Big Blue housing?
A: Yes, it is designed for 4.5" diameter Big Blue housings. It fits most standard sumps and caps. Please double-check your housing's internal dimensions.
Q4: Is the material food-grade?
A: Yes, the polypropylene used is FDA-compliant for drinking water contact. It does not leach harmful chemicals.
Q5: Does this filter remove bacteria or viruses?
A: No, 5 micron is not fine enough to remove bacteria or viruses. It is a sediment filter for physical particles. For microbiological reduction, you need a finer filter (e.g., 0.5 micron or UF/RO).
Q6: Can I wash and reuse this filter?
A: No, this is a disposable filter. Washing may damage the string winding and compromise filtration. We recommend replacement for optimal performance.
Q7: What packaging options do you offer?
A: Standard packaging: individually shrink-wrapped or bulk pack. We also offer custom labeling and private branding for volume orders. Please inquire.
Q8: Do you provide samples for testing?
A: Yes, we offer free samples for qualified buyers. You only need to cover shipping costs. Contact us to arrange.
