BWT Soft Filtered Water Extra Replacement Cartridge for BWT WaterPitcher 3 Pack - 814873

The mineral calcium occurs in varying concentrations in water and is expressed in °dH (degrees of German hardness). Calcium is not visible, but forms deposits when heated, depending on the degree of hardness. These deposits damage electrical household appliances such as fully automatic coffee machines, coffee makers, water and tea boilers.

The BWT filter cartridge Soft Filtered Water Extra is specially designed to treat water with a very high degree of hardness (over 15° dH). The reliable reduction of water hardness protects household appliances from limescale deposits. The specially developed filter also reduces heavy metals (such as lead, copper) as well as odour- and taste-disturbing substances such as chlorine. This turns tap water into noticeably softer water for unrestricted enjoyment. 

Protecting household appliances. Lime-containing water leaves unsightly limescale deposits in household appliances such as kettles or coffee machines. This not only leads to poorer heat transfer and thus to increased energy consumption, but also to the fact that the function of the appliances is impaired and their service life is shortened. In addition, limescale deposits favour the growth of microorganisms such as bacteria.
