The USTM replacement filters are made of high-quality polypropylene threads. By applying a special wrapping method of the thread on the core, we have created a product with a gradient structure. The density of the fibers increases towards the interior.

The contaminated water flows through the filter towards its core. The impurities present in it are covered by micro-pores, whose diameter decreases towards the interior. Large particles are obstructed near the surface, while smaller ones are trapped in deeper layers. This increases the filtration levels, permeation efficiency, and the filter's lifespan.

Modern technology and exquisite craftsmanship allow the filters to remove pollutants such as rust, sand, mud, and airborne particles, with a diameter smaller than 1 micron.
