Everyone knows we should drink at least 8 glasses of purified water every day for optimum health. However, really drilling down to the source of this abundant and vital source of life - some of us could very well be doing more harm that good. It is important we really get this one right.
The age old debate still stands with regards to water sanitation. It does seem contradictory that our water supplies are made safe to drink by adding poisonous chemicals to it. The long-term safety of both chlorination & choramination has not been conclusively proven. Although these substances have been used to disinfect water for 70 years there have been few systematic health studies of the effects on humans, and the studies that have been undertaken have raised more questions than they have answered.
I don't want to freak anyone out, by all means, drinking water from an unfiltered tap is definitely more beneficial than chugging down a can of coca cola. But there are ways to ensure we are getting the premium drop of our H2O. All water filters use a substance to trap, absorb or modify pollutants from the water that flows through them. Some work by trapping the pollutants mechanically with an ultra fine sieve or strainer, while others use a process called adsorption in which the contaminants are retained within the microscopic pores of the medium.
In deciding on a water filter it is best to consider four factors:
- The quality of the tap water to be treated
- The degree of refinement required - which contaminants do you wish to eliminate?
- How much you are prepared to spend on the equipment - prices vary from $30-$1500, depending on the degree of purification required
- The frequency and ongoing cost of maintenance
All hail the original fountain of youth!
