What is reverse osmosis is a common question these days and to also answer what does reverse osmosis do, we need to look at how they work and why they could be harmful to your long term health.

This is a process that exposes water under pressure to a semi permeable membrane with a very fine pore structure. Because most inorganic contaminants have a larger molecular size than water, the membrane rejects certain contaminants, minerals and a large part of the water.

But many synthetic chemicals like pesticides and herbicides have a smaller molecular size than water, they can pass through the filter so another carbon filter is also needed. So what is reverse osmosis good for?

They are quite effective for removing chlorine but when you ask what does reverse osmosis do, it strips out vital minerals like calcium and potassium which we need to remain healthy, otherwise we run the risk of becoming mineral deficient. Many people disagree and say we can get these from our diet, but we absorb them much better from water than any other source.

In fact, the World Health Organization actually sates that we should all drink water with the minerals in.

In addition these systems will discard around 2-3 gallons for every 1 gallon they use and many require a large storage tank and expensive maintenance.

The most effective on the market today, if you want to get rid of 99.9% of all the harmful contaminants and still have those essential minerals left in, are activated carbon filters. The very best have a multi-stage process and ion exchange.

These do not waste water, are very inexpensive to buy starting at around $120 for a countertop, and will leave your water purer and safer than any other system on the market today.

So what is reverse osmosis, well in my opinion it is outdated technology that is best avoided.
