String-Wound Polypropylene Sediment Cartridge - 4-Pack (5 Micron, 10x4.5) - Compatible with Various Brands - Made in USA

Proudly manufactured in the USA, the USWF-SW5-1045 is a 5 micron 10"x2.5" string wound sediment replacement filter. This filter is constructed from FDA Title 21 compliant polypropylene string wound around a polypropylene core, ensuring a high quality product that has been independently tested to NSF/ANSI standards 42, 61, and 372.

String wound filters, such as the USWF-SW5-1045, are commonly used in well water applications due to their ability to handle a wide range of particle sizes. The unique design of string wound filters provides a large surface area for dirt holding, with the string being wound tighter at the core than at the surface, allowing for excellent dirt holding capacity for non-uniform sediment.

Unlike many string wound cartridges that contain cotton fibers made up of over 90% cellulose material, the USWF string wound filters are made only with polypropylene fibers. This makes them the ideal choice for sediment filtration in untreated well water.

The USWF-SW5-1045 is a compatible replacement for popular string wound sediment filters such as the Pentek WP5BB97P, Culligan CW5-BBS, and Hydronix SWC-45-1005. It is easy to install, fitting into most standard 10" x 4-1/2" filter housings including Pentek, Culligan, and American Plumber.

Constructed with durable FDA Title 21 compliant polypropylene fiber string, the USWF-SW5-1045 offers superior filtration with a gradient structure that has a tighter weave at the core than at the surface, maximizing dirt holding capacity and extending filter life.

By choosing the USWF-SW5-1045, you are not only investing in a high quality product, but also supporting American workers as this filter is proudly manufactured in America. Trust in the USWF-SW5-1045 for superior sediment filtration in your well water system. Compatible with SWC-45-1005, SWC451005, SWF-45-1005, CW5-BBS, 355214-43, 355217-43, WPX5BB97P, WP5BB97P, and SF5-10-425.
