They actually don't filter the water in exactly the way that's best for your health.
And, they potentially don't leave your water tasting as good as it should.
Let me explain why.
Let's explore my first point.
Reverse osmosis water filters are not the best for optimum health.
What is the best filtered water? What does it contain? Does the purest water as far as health is concerned only contain two parts hydrogen to one part oxygen? Or are there other elements that need to be present? In other words, does reverse osmosis make water safe to drink? To answer this question, we can look at what naturally occurring pure water is like.
After all that's what we evolved to drink.
(Or were designed to drink.
) Naturally occurring pure water contains not only "H2O", but also a host of trace minerals that our bodies need for the proper maintenance of our health.
Now, here's the problem with reverse osmosis.
When you filter water with reverse osmosis, the water comes out demineralized.
That is, naturally occurring minerals like calcium, potassium, and magnesium are all taken out of the water.
There are several reasons demineralized water should be suspect.
And this gets right back to the disadvantages of reverse osmosis.
One, there's no natural water supply on earth that's demineralized.
We did not evolve to drink water without these trace minerals in it.
Our bodies have to have these minerals in small amounts.
Take calcium, for instance.
Your body uses calcium for several important chemical processes.
As a matter of fact, if your body doesn't get the calcium it needs through your food and water, it will actually take it from its own bones! One result of not having enough calcium in your body is osteoporosis.
With the fact that hip fractures are one of the major causes of death in older people, you can see why maintaining a healthy amount of calcium in your body is so important.
The same can be said for potassium, magnesium, and indeed for all of the trace minerals routinely found in water.
There are some scientists who believe that long-term consumption of demineralized water can result in other health issues, including cancer.
The World Health Organization, for instance, states that "drinking water should contain minimum levels of essential minerals.
" This is actually one the big disadvantages of reverse osmosis--it results in water that's not as healthy for you as it should be.
Potentially it results in water that's damaging to your health.
So, does reverse osmosis make water safe to drink? Not necessarily! The other big disadvantage is that demineralized water tastes flat.
Minerals are what give our water its distinctive taste.
When you take those minerals out, all you have left is a flat tasting, unsatisfactory water.
How long do you think you're going to drink that?
