String Wound Whole House Sediment Filter Cartridges in 10- and 20-Inch Sizes, 2–6 Packs by PUREPLUS
String-wound whole-house sediment filter cartridges use polypropylene microfibers in a graded structure that is denser inside and more open outside. This construction captures sediment, sand, rust and discoloration before those particles reach later filtration stages, plumbing or household equipment.
The listing offers 10 by 2.5-inch, 20 by 2.5-inch and 20 by 4.5-inch formats in two-, four- or six-count packs. Detailed performance evidence covers the 5-micron 10 by 2.5-inch cartridge, including 2.5 GPM flow and a three-to-six-month or 13,000-gallon service estimate. Match dimensions and housing requirements before selecting a variant.
