Tips

The string insert, also known as a nonwoven insert, is one of the popular types of inserts used in water filtration. It operates on the principle of mechanical filtration, where impurities are trapped by the dense weave of fibers of the strings.

✔️ Traps all impurities up to 10 microns in size
✔️ Features a gradient structure, ensuring more precise and effective filtration
✔️ The USTM insert is characterized by a higher density of fiber weave compared to other inserts available on the market
✔️ Works great in whole house or apartment pipe filters and in kitchen water filters under the sink
✔️ Recommended for protecting plumbing systems, household appliances, and fixtures
✔️ Has PZH certification
✔️ Manufactured in Poland

By changing the density and type of fibers along the insert, it is possible to better capture various types of impurities. Fibers of different densities can effectively trap impurities of varying sizes, leading to better quality of purified water.

Thanks to the gradient structure, string inserts can have a longer service life before clogging, which translates into less frequent replacements and lower maintenance costs for the filtration system.

✔️ filter height: 25 cm
✔️ diameter: 5.5 cm
✔️ lifespan: up to 14000 L/ up to 6 months*
✔️ flow rate: up to 25 L/min
✔️ filtration accuracy: 10 Microns
✔️ number of pieces in the set: 1
* the lifespan of the insert depends on the quality of the incoming water
