“REVERSE OSMOSIS IS THE ONLY WAY TO FILTER ……..” (SOMETHING – FILL IN THE BLANK)

March 23, 2011

This line is endlessly repeated by individuals and all over the web.  Don’t believe it.

Reverse osmosis is a fairly effective way to separate contaminants from the water you want to use.  Membranes allow pure water through while holding back water with contaminants in it, like fluoride, chlorine and heavy metals. 

As Wikipedia says:  “Reverse osmosis (RO) is a filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane.” 

It seems clear to us that it is far better to use filter materials selected and fashioned to naturally remove the contaminants you don’t want, and leave the trace elements that you do.  The technology has existed for decades and is very affordable for home unit.

Health Issues for Reverse Osmosis

  • Reverse osmosis removes nutritional minerals (trace elements like magnesium, potassium and calcium) that the body needs
  • Removing minerals drops the pH of your drinking water, which reduces free radicals, shown to increase risk of cancer
    • So you should rebuild your water if you use ro
  • Because reverse osmosis removes trace elements from the water, when the water is in your body, it tries to replenish itself – by taking trace elements from you! (see footnote *)
  • It seems that many drugs, which we know are in the water, are not removed by reverse osmosis
  • Reverse osmosis is not particularly effective on many synthetic chemicals like herbicides and pesticides
  • RO lets molecules and ions through, or not, based on size.  This is not the best basis to ‘sort’ on.
