If you live in Poole, Bournemouth, or Christchurch, you're no stranger to hard water. The high levels of calcium and magnesium in our water supply cause limescale buildup in kettles, taps, and plumbing fixtures. If you're looking for ways to reduce limescale, you might be wondering: Do Water2 filters reduce limescale?

How Much Does the Water2 Filter Reduce Limescale?

While this isn’t a complete solution for softening the water coming out of your kitchen tap, it helps reduce build up slightly while preserving essential minerals like calcium and magnesium, which are beneficial for your health.
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.
