Many people,when searching for the purchase of a water
filter,start their quest as they have discovered that the
water supplied by the net in their area is hard.
Indeed this is a problem,because hard water causes many
problems to the piping net ,to electric fuses of washing
machines and dishwashers,to faucet heaters,home
heating systems,boilers etc.Another problem is that hard
water makes it impossible for shampoos and soaps to
foam.When people wash their hair they realize that it
becomes blur while conditioners become less effective.
What people do not know though is that hard water is
desirable as drinking water up to a certain extent.
Let's try to explain as simply as possible what Hardness
of the Water means.
By the term Water Hardness we mainly mean the
aggregate of dissolved Calcium and Magnesium Salts.
There are two types of Hardness:
A) Carbonate Hardness(or temporary hardness)which is
caused due to carbonate and bicarbonate salts in water.
B)Non carbonate or Total Hardness which measures the
concentration of dissolved Calcium and Magnasium salts
What causes the most common problem of Salt Sediment
is Total Hardness.The best sourse of soft water derives
from rain and snow.
The water in the Amazon Rainforests is actually very soft
However,the great issue of drinking water and its
hardness is not considered as a contaminant.
Nowadays,the view point that the water with no Calcium
or Magnesium Salts may be harmful for the human
organism is established more and more,because of its
large flowing into our cells.That is why sea fish would
die if we tried to relocate them into distilled water;
because their red cells would be destroyed.
Extensive studies over the last years in very large
samples of the population have confirmed the view that
consumption of rich in Calcium and Magnesium Salts
drinking water has beneficial effects on the
Cardiovascular System and not only.
In areas where water is hard ,the cases of Cardiovascular
diseases appear to be on a decrease.Recently the World
Health Organisation introduced a research committee in
order to define the necessity of the presence of Calcium
and Magnesium in drinking water.
Below we briefly present some conclusions:
The World Health Organisation held an International
Convention about how Calcium and Magnesium in
drinking water can affect human health.In this
convention where approximately 200 medical researchers
were invited and participated,studies were presented
which indicated a possible connection between the
insufficient consumption of Magnesium and the increased
inclination towards heart diseases,high blood pressure
and even diabetes type 2,since many people who live in
areas where the water is rich in minerals have had low
percentages of heart attacks and high blood pressure.

The World Health Organisation has come to the conclusion
that the longlasting consumption of distilled water can
lead to mineral insufficiency and generally health
Therefore,it seems that the water in its natural form
enriched with all its trace-elements such as Calcium,
Magnesium,Pottasium is what human organisms during
the last hundreds of thousands of years of their develop-
ment have adjusted themselves to drinking.
