WHY PURIFY YOUR WATER?

 

Contamination with lead, a metal harmful to health, via old pipes. Appearance of rust. Use of aluminum to treat water, a metal believed to promote the onset of Alzheimer's disease. Recurring scandals linked to nitrates and pesticides. Little-known threats such as radon, a radioactive gas. Microplastics invading our environment. And new fears about the use of drugs and endocrine disruptors. There's a lot of doubt surrounding the water in our taps today, even from the best sources.

WHICH METHOD FOR WATER TREATMENT?

The carafe filter

The best-known tool for filtering tap water is undoubtedly the carafe filter. The most widely used of these work with filter cartridges that have a maximum lifespan of 100 liters. That's not much, and it goes without saying that the cumulative cost of these consumables and the waste they generate are not negligible. ANSES urges caution in the use of filter carafes, and reminds us that they are not designed to render non-drinkable water potable(Source).

The osmosis unit

The role of the osmosis unit is to purify tap water by eliminating most of the elements present in the water, using activated carbon to capture chlorine and a membrane to separate the purified water from other undesirable elements, as well as minerals. This method has one major drawback: the osmosis unit uses an average of four liters of water to produce one liter of pure water. What's more, it is sometimes necessary to use a softener upstream to eliminate limescale and enable efficient operation. Hardly an acceptable waste of water.

HOW DOES THE BERKEY SYSTEM WORK?

The Berkey purification system operates off-grid and without electricity.

  • Simply pour the water to be filtered into the upper reservoir and gravity takes care of the rest.
  • Water enters and passes through the Black Berkey filtration elements, which capture bacteria, viruses, heavy metals and chemical contaminants.
  • The lower reservoir collects purified water ready for dispensing via the integrated tap.
