General Filtration’s HSF, PP6 and PP7 high purity polypropylene cartridges are made of 100% FDA-compliant polypropylene resin, free of any additives or binders, making them inert and chemically resistant. The density gradient formed by the spun polypropylene fibres allows for true depth filtration with enhanced dirt holding capacity. Our polypropylene depth cartridges are available in a variety of micron ratings (1 – 200), lengths, and end-fittings to ensure the perfect fit for the application.
