Membrane Solutions 50-Micron 10x2.5-Inch String-Wound Whole House Water Filter Replacement Cartridge — 6 Pack

Meet the Membrane Solutions 50-Micron 10x2.5-Inch string-wound replacement cartridge, designed as a reliable first line of defense for well water and whole-house filtration. Built with food-grade polypropylene, it is lead- and BPA-free, and odorless, ensuring a clean, consistent filtration experience.

This cartridge uses a string-wound construction that offers four times the dirt-holding capacity and double the flow rate compared with standard PP sediment filters. In homes with feed-water that carries a noticeable amount of sediment, this can mean longer intervals between changes and a steadier supply of filtered water.

Universal size and versatile use

Standard 50-micron, 10 x 2.5-inch dimensions make this cartridge compatible with most 10-inch filter housings. It performs well as a prefilter for RO systems and whole-house filtration setups, as well as in a range of commercial and light industrial applications.

• Fits most 10-inch housings, simplifying replacement without new housings.
• Ideal as a prefilter to reduce sediment before RO membranes or post-filters.
• Supports protection for pipes, faucets, and appliances by reducing sediment ingress.

Performance and lifespan

The deep-graded honeycomb structure helps the filter trap larger particulates toward the outer layer and finer particles closer to the core, which enhances dirt-holding capacity and helps maintain steady flow. When water quality is moderate to heavy in sediment, it can help extend the life of downstream filters.

• Long-life filtration: up to roughly 15,000–20,000 gallons depending on inlet water quality.
• Longer replacement intervals when sediment load is moderate, with a practical six-month guideline.
• Odorless and stable materials reduce risk of leaching and maintain water taste consistency.

Safety, standards, and care

Materials are NSF International tested against material requirements (NSF/ANSI 42), confirming a focus on safety and quality in the components. This lead- and BPA-free polypropylene composition is designed to be odorless with minimal risk of secondary pollution.

What you can expect in real use

In everyday homes with well water or municipal water carrying sediment, users often notice clearer water and less frequent clogging of filters and fixtures. The cartridge is designed to be a cost-efficient way to begin or augment whole-house filtration while preserving household water quality.
