REVERSE OSMOSIS ('RO') : What's The Catch?

There is now growing empirical evidence that RO processed water does not hydrate humans and animals!!! This can result in a progressive dehydration. Dehyration can be dangerous, very dangerous to longer term health. Read what medical Dr F Batmanghelidj MD says about dehydration HERE. There is more about dehydration HERE.

Imagine if one drinks 8 glasses of RO processed water EVERY day, and yet perhaps is still dehydrated at a cellular level? All water used in the Auckland drinking system, which has been sourced from the Waikato River, has been RO processed/refined/treated.

This RO process has widespread use today, as a part of modern 'state of the art' filtration/purification systems, to try to get many nasties out of drinking water. Indeed it has in recent times become a sort of 'revelation'. RO began as an invention to separate salt from seawater - to create drinking water from the sea. It has now gravitated to become one of todays most used processes: by city councils, in industry, with much bottled water, and in some homes as so many people try and try to clean extremely polluted water, and others do so with an unrealistic imagination that it somehow makes even reasonable ok water 'better'.

BUT AT WHAT RISK to the drinker of using any RO process with drinking waters?

  • Dr Mercola suggests the RO process will remove chlorine, inorganic and organic contaminants in your water, about 80 percent of the fluoride and most DPBs. A major drawback he suggests is the expense of installing an RO filter, as most need a plumber to get up and running --- although he also warns about incorrect installation being a potential danger .  He uses an RO system himself, but notes he then re-mineralises his RO treated water, so it is not distilled state when he drinks it and he also cools it to try to get strucutre back. He is not as negative about the RO process (at this time) as are some other water researchers and health practitioners.
  • Dr Theo Colburn suggests the RO process WILL NOT delete from ex sewerage any of the tiny endocrine disruptors, which can act negatively on humans at as low as parts per trillion --- see her videos HERE.

  • Dan Vitalis on danger of Reverse Osmosis- see in our Cinema video 1.1 HERE.
    Dan Vitalis says in that video:
    “RO water is also not my favourite, and here are a couple of reasons.  Water molecules are pushed through a very fine membrane, it scrambles and dis-assembles molecules-water coming out at end of RO process has no structure- I cannot get hydrated from this water”.

  • Doctor G (Doctor Gerhauser)  on danger of Reverse Osmosis- see in our Cinema video 1.2. HERE Doctor Gerhauser also writes about RO on his website, with this warning:
    “Reverse osmosis water treatment removes the important macro, micro, trace and ultra-trace minerals and may otherwise damage the water. RO can inadvertently add toxins by causing leeching of compounds into the water from anything that contacts it and from the plastic filter. Numerous studies show the adverse effects of low mineral water, although most of these are old. In practice, it has been noted that people hydrating with RO don't do well on our nutritional balancing program, so we avoid it.”

  •  The web site Aqua Technologies state some biochemists suggest a pentagon shaped or five sided structured cluster of water molecules (instead of the hexagon shaped cluster) might be the residual structure of water treated by reverse osmosis processing/treatment. 

    The web site Aqua Technologies  ( also state what one can conclude at this point is that there seems to be a distinct, "un-natural" structure to the all-important aspect of cellular water in both illness prone humans, disease producing proteins and reverse osmosis water.

    While the process of "osmosis" is a known NATURAL phenomena, the process of "reverse osmosis" is EXACTLY OPPOSITE to that original, natural(osmosis) process. In other words, REVERSE osmosis is an un-natural process---and appears to be producing a relatively clean but un-natural type of water.

    It is possible that in the rush to produce water treatment systems(for drinking) which produce water which is relatively free of inorganics, heavy metals and organic contaminants, the equipment engineers have overlooked perhaps the most important aspect of water itself---its intrinsic, natural structure and its healthful aspects for the body.

WHAT RISK with REVERSE OSMOSIS WATER --- This information about RO and these  telling points are summarised by Lawrence Wilson BSc on:

Reverse osmosis or RO is by far the most common man made method of purifying water on earth.  It involves passing water at high pressure through a plastic membrane with tiny holes in it.  Most minerals and chemicals are too large to pass through the membrane and remain behind, resulting in the formation of a largely mineral-free, chemical-free and pathogen-free water.

The design of most RO units includes a way of back flushing the membrane constantly to hopefully prevent excessive buildup of solid matter on the plastic membrane.  This is important or the membrane would be destroyed quickly.  The membrane usually lasts about a year, at which time the water quality deteriorates and the membrane must be replaced.

Gases, such as chlorine, can pass through the membrane.  For this reason, most reverse osmosis units also usually contain pre- and post-filters.  The pre-filter extends the life of the membrane by removing larger particles and certain chemicals.  The carbon post-filter further purifies the water, removing chlorine and other gases that may pass through the filter.

RO is the most commonly used methods of producing pure water on planet earth.  It is used in almost all home and commercial "drinking water" machines such as those in water stores, supermarkets and health food stores.  It is also used industrially in bottling plants for soda pop, soups, juices, beer and many other drinks.  It is also used on all ships, some aircraft, and in many other applications.  It is much cheaper than distillation.

Advantages of reverse osmosis water.  

These include its low level of toxic metals, toxic chemicals and pathogens, and its low cost.

Disadvantages of reverse osmosis water. 

Unfortunately, RO water has many disadvantages:

1. RO water, in general, does not hydrate the body well.  This is its worst aspect.  It is unfortunate, but we see it over and over again.  The plastic membrane must damage the water in some subtle way that I do not understand.

2. A residue from the plastic membrane seems to find its way into the water, and then into the body.  This is a consistent finding in everyone who drinks RO water.  So it adds a new toxin to the body, even though the water is quite pure in other ways.

3. The water is extremely yin in Chinese medical terms.   This may be because it lacks minerals and because it is contaminated with plastic from the RO membrane.  The yin quality is harmful and best avoided.

4. There is evidence from a few clients that RO water damages the third energy center or chakra.

5. There is no simple way to test the quality of the water.  As the plastic RO membrane and pre-and post-filters age in a reverse osmosis machine, the water quality declines.  A simple total dissolved solids or TDS meter may not detect chemical contamination.

6. Carbon and other filters in RO systems can become contaminated with bacteria and viruses easily.  Manufacturers suggest replacing the carbon filters at specified intervals or after a certain number of gallons have been produced.  However, these are just averages.   Other than the taste, it is most difficult to assess the cleanliness of the carbon filters.

7. Reverse osmosis water is severely mineral deficient and has an acidic pH.  As with distilled water, it does not supply the body with needed trace minerals, and it may have a mild chelating effect.  This means that it may remove some vital minerals from the body.

The acidic pH is also a slight problem.

8. RO wastes a lot of water that must be used to backflush the system.  It also causes pollution because the plastic membranes do not biodegrade quickly. The polycarbonate plastics degrade slowly in the landfills.  Filled with toxic substances, they represent a source of long-term pollution. Extremely high-temperature incineration, which is gaining in popularity, is the best form of disposal of the membranes that I am aware of.

Summary.  Water filtered by reverse osmosis or RO is not good drinking water, in my experience. Its effects can be terrible, including even kidney failure.  I know that sounds extreme, but several cases have occurred that I know about.

It does not matter if someone has added minerals back to the RO water, boiled it, or done other things to it like praying over it or “energizing” it in any way that I have seen, so far.  These methods do not seems to undo the damage to the water that occurs due to passing it through the plastic RO membrane.  Please avoid all water made this way for best hydration.

Bypassing the RO membrane on a home water filtering system.  

Many people have an RO filter on their home or just their sink.  If you wish to use this system for carbon filtration, it is fairly easy to bypass the RO part of your filtering system, in most cases.  This will allow you to keep using the carbon filtration part of the system, which is fine.

Open up the cylinder or container on your filtration system that contains the RO membrane.  Then remove the RO membrane, and close up the container tightly.


  • Very few people know which minerals they need to add.  Commercial preparations such as electrolyte solutions often do not contain optimal mineral levels for each person.
  • Adding salt or sea salt to water may detoxify the body a little, but is a dangerous practice, long term, because the high sodium content can unbalance the minerals in the body by competing with other mineral absorption.
  • Most mineral preparations are not pure enough and many, such as coral calcium, can contain some toxic minerals as well.
  • Reverse osmosis  water, in particular, is extremely “hungry” and adding minerals to it will cause them to be absorbed into the water easily, and then cause them to be absorbed into the body cells quickly and thoroughly.  This is good if the minerals are pure, but most are not pure enough, no matter what they say on the bottle.  As a result, the person is slowly but surely poisoned by the toxic minerals.
  • ASK if your drinking water has been RO treated - our spring water has NOT.
  • Many researchers/writers today are beginning to warn about Reverse Osmosis systems used in processing......see some in videos shown now on our Cinema page HERE
