Watts-(SF5-20) Watts String Wound Cartridge Standard 20 in

The Watts SF5-20 is a 20-inch string wound sediment filter cartridge built with 100% polypropylene construction for superior chemical resistance and zero media migration. Rated at 5 microns, this food-grade cartridge handles temperatures up to 140°F and pressures up to 40 psi, making it suitable for both under-counter and whole house filtration applications.

COMPATIBILITY & APPLICATIONS

Where the Watts SF5-20 Fits

This 20-inch cartridge is designed as a replacement filter for standard whole house or under-counter sediment filter housings that accept 20" x 2.5" cartridges. The 5-micron rating makes it effective for general sediment reduction including sand, silt, rust, and particulate matter in municipal or well water systems. Its polypropylene construction resists a wide range of chemicals and eliminates the risk of fiber shedding or media migration that can occur with cheaper cellulose or cotton-based filters. Use it as a pre-filter stage ahead of carbon blocks, reverse osmosis membranes, or UV systems to extend their service life. Meets FDA standards for direct contact with potable water and food-grade beverages.

💧 Pro tip: String wound filters like the Watts SF5-20 handle higher dirt-loading capacity than pleated designs at the same micron rating, which means longer service intervals in sediment-heavy applications. Replace every 3-6 months depending on water quality and flow demand.
