The Lelit In Tank Water Softener needs to be recharged once every 70 liters, less water passing through, or monthly. Fits most Lelit espresso machines, including the Lelit Bianca, and other brand espresso machines.
The Lelit In Tank Water Softener removes limescale causing agents and minerals, such as calcium and magnesium, from the water. This softener does NOT filter the water for chlorine, other mineral particulates, etc just as most water filters do not soften the water.
Please remove this softener when descaling to avoid damage. In most cases, you should replace the Lelit water softener every 6 months at minimum.
