In 1984 Healthy Water for a Longer Life was published and later, a summary of the book called Healthy Water. Along the way people wanted to know what water treatment systems I recommended to help create a better, healthier drinking and bathing water.
In my mind there are several good filters and water treatment systems available. The Healthy Water booklet outlines what to look for and explains how to evaluate the performance tests to make an informed choice.
The bottom line: a proper, decent drinking water filter needs to pass what is called the ANSI/NSF for Standard 53. Many filters only test for Standard 42--- for aesthetics, taste and odor removal. That is not good enough.
The Standard 53 test is for a host of commonly found volatile chemicals, heavy metals, pesticides and other harmful agents. Make sure the fliter you purchase meets this standard.
Beneficial minerals like calcium and magnesium are not part of the Standard 53 protocol. In genereal, water filters do not remove healthy, dissolved minerals.Here's a list of contaminants removed by filters that meet Standard 53:
ethylene dibromide (EDB)
heptachlor (H-34, Heptox)
