Water filter which prevents limescale in the Beurer LB44
Lime scale is a chalky, hard substance that builds up due to calcium carbonate deposits in water.
Approximately 70% of the water used throughout various countries is naturally hard, meaning it contains a high mineral content, including calcium as well as various other salts. It is true that these help to maintain health (for example, calcium promotes healthy bone growth); however, calcium deposits and build up can have disastrous effects on devices that use water frequently. Although Calcium carbonate is soluble in water, it becomes increasingly difficult to break down the composition when it is exposed to temperatures higher than 70 °C, thus leading to more deposits where water is heated, or warmer. This becomes problematic with certain appliances as the build-up may prevent energy efficiency due to a lack of water flow. This results in higher costs for running water, and ultimately leads to energy being wasted.
