Water is a highly processed product, as it comes out of the tap. It has been filtered, sterilised, chlorinated, fluoridised, - and pressed through pipes of sometimes questionable quality.

Water is in every cell of our body, it is the solvent of life.  We can live without food for a while, but not without water. It is too often ignored, as a fundamental ingredient of a healthy life.

Ideally, we want clean water, which still contains the natural minerals and life forces.

You can either buy spring water, but then there are the issues of how they clean their bottles, whether bottles are BPA free, etc. which need to be resolved.

Alternatively, you can use a filter.

Available are a number of filtration technologies, as you can read, below. 

It also is  good idea to consider a whole-house filter, especially if your water is highly chlorinated.  The chlorine fumes under the shower can be toxic, and many people complain about skin conditions, caused by tap water.

Below, I copied information from the Ecodwell Newsletter of the International Institute for Building-Biology and Ecology, to give you a summary of filtration techniques..

I'd just like to add that there are products on the market, that claim to revitalise the water, after filtration. For water to be healthy, it needs to be much more than clean.  

There are also water energisers, like the models based on Viktor Schauberger's or Johann Grander's research. 


'Seven Water Filtration System Basics':

1) Activated Carbon/Carbon Filters:

These vary in effectiveness, but generally carbon filters remove contaminants such as lead, mercury, asbestos, and several other volatile organic compounds (VOCs). Activated carbon chemically bonds with contaminants and removes them from the water but it also has its limitations. These do not remove inorganic compounds such as fluoride. Additionally, depending on the NSF certification, some are effective at removing chlorine whereas others only remove chlorine taste and odor. Here are the two most common:

Carbon Block:These filters have a larger surface area than that of granulated activated carbon fiber which makes them more effective. This type of filter is made by heating activated carbon into blocks. Keep in mind though, that the speed at which water flows through the filter also determines how effectively filtered it is.

1) Granulated Activated Carbon:

Carbon block filters work better than this type of filter. Granulated Activated Carbon contains tiny grains of activated carbon and they have a small (I think, they mean HUGE) surface area. Their performance is also affected by how fast water flows through them.

2)Ultraviolet (UV):

Ultraviolet light can be used to kill certain microorganisms and bacteria; however, this process can not remove chemical pollutants.

3) Distillation:

This type of filter uses heat to vaporize water and then the steam is condensed back to water. A large number of bacteria are removed this way, as well as chemicals and viruses. Distillation does not remove volatile organic chemicals (VOCs), chlorine or trihalomethanes.

4) Mechanical Fibers:

These work like ceramic filters by removing solid contaminants. In order to clean the water more effectively, they are used in combination with other types of filters.

5) Reverse Osmosis:

This can be effective at removing contaminants such as arsenic, fluoride, nitrates, hexavalent chromium and many other contaminants. In order to filter the contaminants, water is pushed through a semi-permeable membrane, where particles larger than water molecules are blocked out.

6) Deionization:

In case you would prefer a more complex form of filtration, deionization removes electrically charged molecules and iron salts through an ion exchange process. Microorganisms and non-ionic compounds (ie: many VOCs or trihalomethanes) can not be removed through an ion exchange process.


According to the EPA, Bromate occurs when bromide in the water reacts with the disinfectant, ozone. It is great at killing bacteria and additional micro-organisms, but works best when paired with other filtration methods as it is not effective at removing chemical contaminants. 

Which System to Choose:When filtering drinking water for your home, youorganisms and compounds, all of which require advanced filters to remove.

POU (Point-of-Use) -

These types of filtration devices introduce water at a single water connection (e.g.: kitchen sink) and include under-counter (eg: Reverse Osmosis), countertop e.g.:

Filtration never before available in a pitcher and Berkey) or faucet mounted filters (eg: PUR or Aquasana shower filters).

POE (Point-of-Entry)

These are installed at the main water line where water enters the home. They are also referred to as Whole House Water Filters, because they provide filtered water to all sinks, baths, showers, dishwashers, refrigerators, washing machines and toilets basically, the entire house (eg: Rhino whole house water filter).

No single filter can remove all undesirables from your drinking water but using a filter lowers the risk of infection or long-term exposure to chemical contaminants. In order to get healthy water for your home, you may need to combine two or more filtration systems. Be sure you understand what the filter removes and test your water (if necessary) before purchasing the appropriate filter for optimal health.

Don't forget:  Change your Filters!

No filter will give you consistently good performance over the long term unless it receives regular maintenance. As contaminants build up, a filter can not only become less effective, but actually can make your water worse by starting to release harmful bacteria or chemicals back into your filtered water.
