As a professional manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory brings decades of expertise to the production of our Phenolic Resin Fiber Filter Element. Designed for water treatment and RO pre-filtration, this 20 micron cartridge delivers reliable sediment removal under 100 PSI operating pressure, making it a trusted choice for residential, commercial, and industrial systems. Our factory, with annual export value of US$5-10 million, serves markets across North America, South America, Europe, Asia, and more, ensuring consistent quality and global compliance.
This filter element is engineered from high-quality phenolic resin-bonded fibers, offering exceptional depth filtration and dirt-holding capacity. The 20 micron nominal rating captures fine particles such as sand, silt, rust, and scale, protecting downstream RO membranes and equipment. With a maximum pressure rating of 100 PSI, it withstands typical water system demands while maintaining structural integrity. Below are key technical specifications:
| Specification | Detail |
| Filtration Rating | 20 Micron (nominal) |
| Maximum Pressure | 100 PSI (6.9 bar) |
| Maximum Temperature | 120°F (49°C) |
| Diameter | 2.5 inch (63.5 mm) standard |
| Length Options | 10 inch, 20 inch, 30 inch, or custom |
| End Cap Type | Double open end (DOE), Flat, or 222 O-ring (optional) |
| Core Material | Polypropylene, stainless steel (optional) |
| Flow Rate | Up to 10 GPM (20 inch length at 20 PSI pressure drop) |
Product Features & Benefits:
- High Efficiency Depth Filtration – Phenolic resin fibers create a graded density structure, trapping particles throughout the entire depth of the cartridge, not just on the surface. This extends service life and reduces replacement frequency.
- Excellent Chemical Resistance – The resin-bonded construction resists degradation from chlorine, chloramines, and common water treatment chemicals, ensuring long-term performance in harsh environments.
- Low Pressure Drop – Optimized fiber matrix allows high flow rates with minimal resistance, saving energy and reducing pump load in RO systems.
- Robust Mechanical Strength – Withstands 100 PSI operating pressure and up to 150 PSI burst pressure (depending on length), making it suitable for fluctuating water pressure conditions.
- Versatile Applications – Ideal for municipal water, well water, rainwater harvesting, and as pre-filtration for reverse osmosis, ultrafiltration, and car wash water recycling systems.
- Customizable Options – Available in various lengths, end cap configurations, and core materials to fit standard housings (10" BB, 20" BB, etc.) or custom assemblies.

Frequently Asked Questions
- What is the life expectancy of this filter element? – Service life depends on water quality and usage. Typically, a 20 inch cartridge lasts 3–6 months under normal conditions. For heavily sediment-laden water, more frequent replacement may be needed.
- Can this filter be used for chlorine removal? – No, it is designed for sediment filtration only. For chlorine reduction, a carbon block or GAC cartridge is recommended.
- Is it compatible with standard 10 inch and 20 inch housings? – Yes, it fits most standard BB (big blue) filter housings with 2.5" diameter. Custom sizes are available upon request.
- What is the maximum operating temperature? – 120°F (49°C). Continuous use above this temperature may cause deformation or reduced performance.
- Is the material food-grade or safe for drinking water? – The phenolic resin fibers are manufactured from FDA-approved raw materials (optional certification available upon request). Please contact us for specific compliance documentation.
- Can I get custom lengths or end cap configurations? – Absolutely. We offer OEM customization for length, end cap type (DOE, Flat, 222 O-ring, 226 O-ring), and core material. Minimum order quantity may apply.
- What is the burst pressure rating? – Typically 150 PSI for 10 inch length, with reduction for longer cartridges. Test data is available upon request.
- Do you provide samples for testing? – Yes, we offer sample orders. Please contact our sales team for details.
