Based on my studies, the best way to purify water is to distill it.
Distilled water is prepared by boiling the water and then condensing the steam. This removes all contaminants but the volatile gases, which need to be removed by carbon filtration. Minerals can be added back to the water.
Some will say that distilling water removes the beneficial minerals, but these can either be taken as separate supplements or can be added to water later. And that, in fact, is what many manufacturers of bottled water do.
Distilling creates water with a neutral pH, kills all microorganisms even viruses, and removes fluoride as well as other harmful metals. The one problem is the volatile chemicals, which are condensed in the final water container.
The better distillers have a carbon filter to remove these volatile gases during the condensation process.
Other ways to filter water include reverse osmosis, ceramic filtration, silver impregnated filters, and multilayered filter systems, all of which have their advantages.
The big problem with most filters is that they do not remove fluoride. The reverse osmosis filters remove fluoride but they have to be changed every three months because the fluoride burns holes in the filter. There are people, mostly from the American Dental Association, who are campaigning to have fluoride added to all bottled water, despite clear evidence that fluoridating drinking water not only fails to prevent cavities but actually ruins the teeth, a condition called dental fluorosis.
Most physicians have observed that adults, the elderly in particular, do not drink enough water. This can lead to a number of problems, including a higher risk of kidney disease and a greater risk of sudden heart attacks or strokes.
When you are dehydrated, the blood is sluggish and tends to clog the microscopic vessels in the organs, especially the brain. It also makes the blood more likely to clot, which is what happens with both a heart attack and a stroke. The elderly avoid drinking water, especially in the evening, because they want to avoid late night trips to the bathroom. This is a very bad and dangerous practice.
Many strokes are silent and can occur repeatedly without outward signs, except for a gradual loss of mental abilities and memory. These “mini strokes” involve the small blood vessels in the brain, the very ones that fall victim to dehydration.
