Why filter

Our society and industries today actively release many impurities and pollutants into the environment.

Water is known as the universal solvent because of its ability to dissolve more substances than any other liquid. That is why organic pollutants and other impurities still can be found in the water we drink, impacting the taste and odor. The BRITA® filter, which includes an active carbon made from coconut shell, strongly reduces these impurities and dispenses clean and clear, great tasting water.

The water cycle

How do substances get into the water? Water, our planet’s most precious and life giving resource, has a continuous movement on, above and below the surface of the Earth and changes different states from liquid, solid (ice) and vapour. This constant move from one state to another, and the travel of water through its different form, can impact the quality of water by numerous factors: the presence of minerals such as limestone and dolomite, the agricultural pollution with fertilizers and pesticides, various contamination like oil residues and solvents, and industrial emissions, mainly exhaust gases and dust.

  1. Condensation – Water vapour in the air is changed into liquid water, forming clouds. Clouds may produce rainfall, which is the first route for water to return to the earth’s surface within the water cycle.
  2. Rainfall – Precipitation is the water release from clouds to Earth. Rain, sleet, snow, or hail are hence several primary connections in the water cycle that provides to deliveries of atmospheric water to the earth. Cloud systems can travel immense distances and therefore be potentially a source of atmospheric pollution.
  3. Leaching – Soluble materials in the soil, like salts, nutrients, pesticide, hormones and contaminants, are washed through a lower layer of soil or are dissolved and taken away by the water.
  4. Ground water bed – This is a layer made of sedimentary rocks and mineral particles, an impermeable bed adjacent to the aquifer. This layer delays the movement of the water, because of its low hydraulic conductivity. The ground water can also be influenced by sea water intrusion, what happens in the Nordic countries.

The water coming into the tap water system has been impacted by the water cycle and the impurities it generated.

Although drinking water is one of the most highly controlled foodstuffs – with strict limits on what it can contain – water dissolves more substances than any other liquid. Consequently, water is usually more than simply H2O and its contents can vary greatly. Treatment plants play a crucial role in purifying water and removing un- desirable substances to make it safe to drink – a task they perform to consistently excellent standards. However, the resulting potable water can vary in terms of hardness, chlorine levels, aroma, taste, and more, including particles typically originate from piping. This is why a filter is needed, ensuring a clean, great tasting water at any time and situation.

 

What are the filter components?

Because water can vary widely in its composition, BRITA® developed a range of filters with inner components that suit variant needs:

  • The activated carbon
    made from coconut shells 
    reduces substances that can negatively affect taste or odor such as chlorine.
  • The particle filters
    remove particles like rust and deposits within the filter fleece.
  • The ion exchanger
    resin reduces carbonate hardness to prevent lime scale built up and absorbs metals such as lead and copper.

How does a professional water filter work?

Let’s take the BRITA® Clarity Taste for instance, to see how the filter technology provides outstanding and consistent water quality in three steps:

  1. Water flow
    All the raw water flows through the carbon block from the outside inwards.
  2. Pre-Filtration
    Before entering the carbon block, a nonwoven material retains coarse contaminants (such as sand).
  3. Activated carbon filtration
    Fine pores ensure effective particle retention. Substances that can have an adverse effect on the taste and aroma are reduced.
