Thread Spun filter 20""

A 20-inch Thread Spun filter is a common water filter cartridge, typically made from polypropylene (PP) fibers spun together, used for whole-house or pre-filtration in water purifiers to remove sediments like sand, rust, and dirt, available in various micron ratings (e.g., 1, 5, 20 micron) for different levels of filtration, fitting standard 20-inch housings. These filters offer deep filtration with density gradients, catching larger particles on the outside and finer particles deeper within, and are designed to be replaced every few months depending on water quality.
