Why Keeping Calcium and Magnesium in Your Water is Good For You
Limescale forms due to calcium and magnesium in hard water - minerals that are essential for our health. While limescale build up on appliances and pipes can be frustrating, these minerals offer important benefits:
Calcium: Supports strong bones and teeth, muscle function, nerve transmission, and cardiovascular health. Drinking water with calcium contributes to your daily intake, helping maintain overall well-being.
Magnesium: Involved in over 300 biochemical reactions in the body, magnesium supports energy production, muscle and nerve function, and helps regulate blood sugar levels. It’s also linked to a lower risk of cardiovascular disease.
The Water2 filter enhances water quality while preserving these beneficial minerals. By reducing limescale by around 10%, it may help reduce build up in appliances while ensuring you still get the natural health benefits of calcium and magnesium in your drinking water.

Should You Use a Water2 filter for Limescale?
If your main goal is to drastically reduce limescale, you may need additional solutions such as a water softener or descaling treatments. However, softened water isn’t recommended for drinking due to its high sodium content.
So, if you’re looking for a filter that improves taste, removes contaminants, and retains healthy minerals, the Water2 filter is a great choice. It helps reduce limescale build up slightly while ensuring you continue to benefit from the natural calcium and magnesium found in hard water.
