Limescale is the hard, off-white, chalky deposit found in taps, kettles, hot-water boilers and the inside of some hot-water central heating systems.
Good-quality water filters are specially designed to remove the chlorine and other harmful contaminants in the water, leaving the healthy minerals behind. Limescale is a result of the minerals magnesium and calcium that are left in the water.
Many people are mistaken by the misconception that the presence of limescale means the water is unclean and unsafe and purchase “mineral” and distilled water.
Limescale is visible proof that your water is healthier than distilled water, and even when consumed in large quantities, it is absolutely not harmful!
