Does Reverse Osmosis Strip Out Minerals?

QUESTION:

We are customers of an RO System from US Water.  Speaking with a long time plumber familiar with these systems he stated ours is a very good unit but RO would strip the water of important minerals?  Is this true or false?

Our unit is:

If above is true, what is your recommendation for adding this stripped minerals back into the water prior to reaching the drinking faucet?

ANSWER:

Yes, an RO system will strip out the minerals… it will also remove a plethora of chemical and bacterial contaminants.

So often, people get fixated on the wrong thing.  Reverse Osmosis removes the largest spectrum of contaminants of any water treatment process and it does remove the minerals. However, water is not a significant source of minerals.  Let me say that again: Water is not a significant source of minerals.

If you drank a bathtub full of water a day you might get 10% of the minerals your body needs.  You get minerals from foods and supplements.

It’s an illogical argument: “Let’s get less than 1% of the minerals my body needs but leave in chemical contaminants that have been proven to be cariogenic?”  Some people add minerals back to their water with special filters and go to great length to re-mineralize or attempt to make alkaline water.  IT MAKES NO DIFFERENCE TO YOUR BODY!  Once the water passes through the cell wall, whether the pH is 6.0 or 8.0, it becomes the pH of your body and on top of that, the minerals you can add are but a drop in the ocean.

Let me break it down even more.  Ask these questions:

  1. Are minerals in the water good for you?  YES!
  2. Is water a significant source of these minerals?  NO!
  3. Is water a significant source of cariogenic chemicals?  YES!

In short, it is best to remove the chemicals and minerals and just eat a good diet!  Take a supplement if you want, but try as you might, you cannot get the minerals from the water you drink, and raising the pH of the water to make “Alkaline Water” has become a Billion Dollar Industry that is built on a scientific misconception.  Water that is truly alkaline may have some medicinal benefits but simply raising the pH by remineralization and thinking that makes your water is alkaline is as erroneous as thinking you can defy the law of gravity.

Instead of being focused upon the lack of minerals in RO water, you should be more concerned with contaminants the Reverse Osmosis system is removing.  Things like lead, chlorine, chromium 6, chloramine, pesticides, herbicides, pharmaceuticals, TCE, THM, PCB, GenX and hundreds of other chemicals and contaminants… some that we may have yet to hear about.  That’s one of the best things about reverse osmosis: even if there is some “emerging contaminant” that we have not heard of, the odds are that Reverse Osmosis will remove or reduce it.

I always say “Buy a Filter or Be a Filter” and while reverse osmosis is lot more than just a “filter,” you simply cannot utilize better technology in treating your water.  Of course, some people are going to say that “Reverse Osmosis is wasteful – it wastes 3 gallons for every gallon it makes.”  That is true… and in most homes families use 2 or 3 gallons of water a day, so they might waste 6 to 9 gallons.

Your dishwasher and washing machine waste a lot more than that, and all they are doing his cleaning your clothes and dishes.  A RO system is cleaning your water, so that you aren’t the filter, storing carcinogenic chemicals in fat cells.  Yes, it wastes a little bit of water, but it adds a lot to a healthy lifestyle.  Some people say “I don’t want to waste water, so I have bottled water delivered.”  The bottled water plant wastes the water when it makes it and the smog-emitting truck that delivers it is good right?

If you are thinking about a reverse osmosis system – get the facts and remember, all of our US Water Systems are built right here in in the USA at our factory and we also have the only systems that also kill bacteria.  We think that is very important, and so every US Water Systems RO system includes the Pulsar Quantum Disinfection Polishing Filter which also eliminates the bacteria.

Cheers!

  1. Hello everyone!

    I’ve been drinking “purified drinking bottled (reveres osmosis only) water for 2 years. I found out recently that drinking this water is dangerous for health. After I found about it I taught to quit drinking purified water and start to drink spring water. I tried one day for couple of hours and I had high blood pressure. I stopped it.

    Right now I am still drinking purified water only Total Dissolve Solids (TDS) only 5.

    My question is this, how can I quit purified water, safely, and start to drink normal (spring, tap..) water.
    Please, tell me step by step how to do it.

    Thank you.

  2. Feel free to believe what you want, but there is no credible evidence that drinking water purified by reverse osmosis is dangerous to your health. There is no “normal” water. Many people drink high TDS water and live into their 100’s and many drink low TDS water and live into their 100’s as well. In my opinion, the most important thing is to remove the contaminants from the water and reverse osmosis removes a wider spectrum of contaminants than any other water treatment process.
