Built in the USA, the USWF-SW10-2025 is a 20" x 2.5" string-wound sediment cartridge rated at 10 microns. Polypropylene string meeting FDA Title 21 requirements is wrapped around a polypropylene core, and the filter has been independently tested to NSF/ANSI Standards 42, 61, and 372.
Well water systems commonly rely on string wound cartridges because they capture sediment across a broad range of particle sizes. The wound string provides extensive surface area for holding dirt, and because the winding is denser near the core than at the outer layers, the filter traps uneven sediment loads effectively.
Many private well owners avoid cellulose filters on non-chlorinated water, yet the cotton fibers found in many string-wound cartridges contain more than 90% cellulose. USWF uses only polypropylene fibers, a synthetic material that better resists bacteria, making this cartridge an ideal sediment filter for untreated well water.
