Description
How does it work?
Technical data
Cartridges are filled with ion exchange resin (cationite in a sodium form) with a high exchange capacity of calcium and magnesium ions.
Our ST cartridges shall help you to reduce the issue of hard water in your household. Our cartridge was designed by UST-M engineers to enable the longest possible time in which water stays in touch with the bed. Water flows through the cartridge axially (upwards), remaining longer in touch with the filtration bed. In combination with high ion exchange capacity of the resin it deprives water which has passed through the cartridge of practically all calcium and magnesium ions. As a result, you consume less detergent while doing your laundry, your tea tastes better and there are no unpleasant stains on your mugs and fittings.

- remove calcium and magnesium from water
- prevent from scale formation
- 5 μm pre-filtration
- partially remove sediments
- dissolve existing scale deposits
Hard water (which contains large quantities of calcium and magnesium salts) passes through the ion exchange resin which can be found in our cartridge. As a result, Ca2+ Mg2+ ions are replaced with sodium ions from the resin and water becomes softened. This way, you can solve the problem of sludge and unpleasant stains on kitchen appliances.
Material used: polypropylene, ion exchange resin
