The Lelit In Tank Water Softener needs to be recharged once every 70 liters or less water passing through or minimum once per month. Fits most Lelit espresso machines and other brand espresso machines.
This water softener helps remove 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, the Lelit water softener needs should be replaced 6 months (updated May 31, 2019) minimum.
