Limescale is the minerals calcium and magnesium, and is responsible for the hard white gunk that clogs up your coffee machine. Using a coffee water filter that reduces this hard water extends the life of your machine. The filters also ensure other impurities are reduced from your water, improving taste. By improving the taste and quality of your water, the base of your coffee, you improve the overall taste of every cup you make.
