Limescale is actually a form of calcium called calcium carbonate. Not only is it rich in calcium but also in dissolved magnesium (essential minerals for health). Calcium is naturally present in water. It enters into the water when it passes through the soil before being pumped and made drinkable. Limestone is a natural element, and tap water can provide up to 25% of the daily calcium intake. So why would you want to eliminate it?

Well, Berkey® filters do not eliminate it! The mineral salts remain present in the filtered water for your well-being, unlike pollutants which are removed.

However, if deposits build up in the tanks due to very hard water, it is best to occasionally clean them with white vinegar and warm water, for example. As for the filters, they can, according to recommendations, be scrubbed on the outside with a soft brush or a Scotch-Brite® sponge to clean them and remove any blocked pores.
