Drinking water filtration

As a rule, BRITA water filter systems comprise a mixture of activated carbon and ion exchange resin that is particularly well-suited for drinking water optimisation.
Where the focus is only on enhancing the taste of water, filters with pure activated carbon technology are used.

How BRITA water filters work

BRITA water filters optimise the mains water for preparing hot and cold drinks and dishes. Hot beverages that have been prepared using BRITA optimised water, such as tea and coffee, can develop their full flavour in this way. In addition, limescale will no longer build up as quickly in kitchen appliances used for heating water. Advantages of the original BRITA water filter at a glance:

  • Carbonate hardness (limescale) in the mains water is reduced.
  • The concentration of free and bound chlorine - where present - is reduced.
  • The concentration of lead or copper in the mains water that may be present due to relevant domestic installations is reduced.

Actual filtration occurs through gravity; the water flows through the cartridge from top to bottom, or in the case of filters connected to the water mains, through the water pressure that pushes the water through the cartridge.

As soon as the water comes into contact with the ion exchange resin of the cartridge, it reduces the carbonate hardness (limescale) and, where present, metals such as copper and lead from domestic plumbing. The activated carbon that has been added largely removes existing substances that can impair the taste, such as chlorine and chlorine compounds. The filter material used in BRITA filter cartridges is regularly tested for food grade quality and efficiency by independent institutions.
