Disposable cartridges composed of a column of strong cationic resins for softening.
The cartridges allow to reduce the total hardness of the incoming water by preventing the formation of scaling deposits.
The resins used, certified for the treatment of drinking water, have a high exchange capacity and do not alter the pH of the treated water.
In addition to the resins, the OK57 cartridge has a 5μm carbon block element suitable to remove residual chlorine, odors, taste as well as any suspended particles larger than 5μm.
