Membrane Solutions 20-Micron 10x2.5-Inch String-Wound Sediment Filter – Whole House, 6 Pack

Meet Membrane Solutions 20-Micron String-Wound Sediment Filter

Designed for whole-house filtration and RO prefiltration, this universal 10"-long cartridge brings a practical, maintenance-friendly solution to homes and well-water setups. Built with food-grade polypropylene, it is lead-free, BPA-free, and odorless, helping maintain a clean, consistent water-filtering experience without added flavors or smells.

What makes it stand out

• Four times the dirt-holding capacity and a higher flow than standard PP sediment filters, enabling longer service life and steadier water flow.
• Deep, string-wound construction creates a filtration path that captures larger particulates first and finer matter closer to the core.
• Standard universal size: 20-micron, 10 x 2.5 inches, fits most common filter housings and serves as an excellent prefilter for RO systems or whole-house setups.
• Protects downstream filters, water appliances, pipes, and fixtures from sediment buildup, helping maintain cleaner water supply to kitchens and bathrooms.

Performance and durability

• Long-life filtration capable of handling up to 15,000–20,000 gallons, depending on inlet water quality and sediment load.
• Deep filtration with a dense inner core and a more open outer edge to maximize dirt capture while encouraging a steady flow rate.
• NSF International testing covers material requirements to support safe, stable filtration in residential applications.

Versatility and maintenance tips

This cartridge is ideal as a first-stage filter in well-water or city-water systems, and it also functions well as a pre-filter for RO units. Use in 10-inch filter housings to protect post-filters, faucets, and appliances from sediment-related issues. For best results, replace the cartridge at least every six months or sooner if your water is high in particulates.

Packaged as a six-pack, it offers a convenient, cost-efficient option for households with multiple housings or a proactive replacement schedule, helping you stay ahead of sediment buildup across fixtures and appliances.
