Why Filter Drinking Water
Why should we filter our drinking water?
Consumers are realising that the quality of their drinking water is below, and in many areas, significantly below, the standard ideal. Increasingly, consumers are taking control of the water they, and their families drink
How does a water filter work?
Simply, water pressure quitly forces water through the filter cartridge where chemicals and impurities are removed - thus producing a more healty and more benficial quality of drinking water.
What is it that removes chemicals and impurities?
Carbon. Carbon has a long history of being used to absorb impurities and is the most powerful absorbent known. One kilogram of carbon granules has a square area of 250 acres and can absorb thousands of different chemicals. Granular Activated Carbon (GAC) is by far the world's most widely used and widely recommended water filter process. GAC is excellent for the removal of Chlorine - thus removing the swimming pool taste from your water.
How finely does the filter work?
Sapphire Water Filters have adopted 1 micron as their standard of cartridge specification. Many brands use 5 or 10 micron and some even greater. 1 micron is one thousandth of one millimeter. A human hair is 64 micron on average. The human eye can see 32 micron.
Chlorine:
The use of Chlorine as a water quality control method has gained wide acceptance because of it's low cost and high efficiency in killing just about anything hazardous in the water. The problem with Chlorine is that it is a known poison and the safety of drinking this poison over the long term is highly uncertain.
Chlorine also combines with natural organic matter to form other potent, health threatening compounds. Chlorine is an irritant to our bodies and it's functions. Research continues on this subject. The removal of chlorine from our drinking and cooking water is a powerful health advantage.
Giardia and Cryptosporidium:
Giardia is 7 to 14 microns in size and Cryptosporidium is from 3 to 5 microns. When the environment becomes inhospitable (like when in the presence of chlorine) both parasites can go into the cystic form. The cyst is resistant to chlorine and very hard to kill.
Water filtered to one micron will remove almost all of the above parasites.
NB: It is very important to change your filter cartridge at least once per year... more often if the water quality is doubtful.
