Melt-blown Polypropylene Sediment Filters. The main function of a sediment filter is to remove large and fine particles from our drinking water, such as sand, dirt, silt, and rust particles.

Our Sediment filters are made of fine melted polypropylene, which is then blown and spun in a cylinder-like form.  These filters have a lower density at the surface of the filter with progressively higher density toward the center which enables to capture of particles throughout the entire filter depth.
