The USTM replacement filters are made from high-quality polypropylene yarn. By applying a special method of winding the yarn around the core, we have created a product with a gradient structure. The density of the fibers increases towards the inside.

The contaminated water flows through the filter towards its core. The sediments present in it are trapped by micropores, whose diameter decreases towards the inside. Large particles are blocked near the surface, while smaller ones are trapped in deeper layers. This increases the filtration levels, filtration efficiency, and the lifespan of the filter.

Modern technology and masterful craftsmanship allow the filters to stop contaminants such as rust, sand, sludge, and airborne particles, with a diameter of less than 1 micron.
