How the Minimax M3 Water Softener Works

The Minimax M3 uses twin resin cylinders to deliver soft water 24/7.

Hard water flows through the resin, which removes limescale-causing minerals through ion exchange. When one cylinder needs to recharge, the system flushes it with a salt solution while the second cylinder continues working uninterrupted.

It works automatically and runs on water pressure—no electricity or timers required.
