Anping County Boli Hardware Wiremesh Products Factory is proud to present our Guard Filter Cartridge for RO Water Pre-treatment, designed to deliver reliable and efficient sediment filtration for reverse osmosis systems. With over two decades of manufacturing experience (since 1998) and annual export revenues exceeding US$5 million, we supply high-quality filtration solutions to markets across North America, South America, Europe, Asia, and beyond. This 5 micron, 10-inch, 1-inch NPT food-grade cartridge ensures your RO system operates at peak performance by removing rust, sand, silt, and other suspended solids before they reach the delicate membrane.
Engineered for excellence, this cartridge features a uniform melt-blown polypropylene construction that provides high dirt-holding capacity and consistent depth filtration. The food-grade material meets strict safety standards, making it suitable for drinking water applications. The standard 10-inch length and 1-inch NPT threaded connection allow easy replacement in most standard housings, reducing downtime and maintenance costs.
- High Filtration Precision: 5 micron nominal rating captures 99% of particles larger than 5 microns, effectively protecting RO membranes from fouling.
- Food-Grade Material: Made from FDA-compliant polypropylene, no chemicals or binders are added, ensuring safe and pure water output.
- Robust Construction: Melt-blown fiber structure provides excellent mechanical strength and resists deformation under high flow rates.
- Universal Compatibility: 10-inch length with 1-inch NPT female threads fits most standard filter housings and RO pre-treatment systems.
- Cost-Effective: Long service life and high dirt-holding capacity reduce replacement frequency, lowering overall operating costs.
- Easy Installation: No special tools required; simply screw into the housing and tighten by hand.
