Product information

Description

USTM ST 10 Softening 4302086 is a 10" in-line water filter element with an ion-exchange softening layer designed to reduce water hardness by removing calcium and magnesium ions.

The element offers up to 2,000 litres or 6 months of service life under recommended conditions and supports flow rates up to 6 l/min.

Under-sink point-of-use softening (e.g., FS2/FS3 type systems)
