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

Overview

Meet Membrane Solutions 5 Micron 10x2.5 Inch String-Wound Whole House Water Filter Replacement Cartridge, a universal sediment prefilter designed for well water and home filtration systems. Made with food-grade 100% polypropylene, it is lead- and BPA-free, offering a non-toxic, odorless filtration experience that minimizes the risk of unwanted leaching while you filter.

Why this filter stands out

• Four times the dirt-holding capacity and double the flow rate compared with standard PP sediment filters, which can translate to longer service intervals and steadier water flow.
• Standard universal size (5 Micron, 10 x 2.5 inches) fits most 10-inch housings, making it a versatile prefilter for RO systems and whole-house setups.

Performance and protection

This string-wound design targets sediment early in the filtration chain, helping to protect post-filters, appliances, pipes, and fixtures from clogging and buildup. It can filter out undissolved particulates such as rust, silt, and sand, which may lead to a cleaner overall water supply for daily use.

• The filter is capable of removing up to 99% of sediment (based on typical testing scenarios) and provides a reliable first stage for downstream filtration components.
• The deep, graded honeycomb structure captures larger particles near the outside and progressively smaller ones toward the core, enhancing filtration efficiency and dirt capacity.

Longevity and maintenance

Designed for long life, this cartridge supports 15,000–20,000 gallons of filtered water under typical conditions. Actual life depends on inlet water quality. For consistent performance, consider replacing the cartridge at least every six months or sooner if you notice a drop in flow or increased sediment in the output.

Material and certifications

Material quality is a key benefit: the cartridge is food-grade polypropylene, lead-free, and BPA-free, with NSF International testing focused on material requirements under NSF/ANSI Standard 42. This reflects a commitment to safer filtration materials in home use.

Real-life use cases

Whether you rely on well water or want a reliable prefilter for an RO system, this cartridge offers a practical balance of filtration capacity, compatibility, and ease of use. It’s a suitable first line of defense against sediment that can affect faucets, shower fittings, and appliances, helping you maintain cleaner-looking water and reduce maintenance on downstream filters.

What to expect in your setup

• Fits most 10-inch filter housings, simplifying upgrades or replacements.
• Useful as a prefilter in whole-house systems to extend the life of downstream components.

Note: performance depends on the incoming water quality and system configuration. This replacement cartridge is designed to offer a practical filtration solution without guaranteeing specific outcomes.
