Is Reverse Osmosis Water Good For You?

The reverse osmosis process allows companies to filter out every unwanted contaminant in the water and only leave something close to pure H2O.

This process is also highly used in Arab countries where freshwater is scarce. They use this same principle to filter out all the salt in their saltwater and turn it into fresh, drinkable water.

Using reverse osmosis water is good for you, but it is not recommended to consume it daily.

What is Reverse Osmosis?

Osmosis is a term that you probably had learned and studied back when you were in high school. Osmosis is the process of water passing through a semi-permeable membrane from a less concentrated solution to a more concentrated one.

In reverse osmosis, external pressure is applied. A concentrated solution containing contaminants and microorganisms passes through a semi-permeable membrane, resulting in a less concentrated solution; this is what you want your water to be.

Like many other filtration systems, reverse osmosis starts by removing all the large particles from the water like small rocks, sand, and dirt. Activated carbon then filters all the smaller particles present in the water, such as lead, radon, and chlorine.

The semi-permeable membrane then removes the sodium and other minerals present in the water. Lastly, a post-carbon filter removes all other chemicals that might have slipped through the filters.

Is RO Water Too Acidic?

Is RO Water Too Acidic?

Water that passes through reverse osmosis typically has slightly higher acidity than pure water. Pure water has a pH of just 7, but reverse osmosis water has a 6-6.5, which has the same acidity as egg yolks and cow’s milk.

But a slightly higher ph does not mean that RO water is unhealthy automatically. Reverse osmosis removes 99.9% of all the unwanted particles in our water, and its resulting pH is very close to that of pure water, which can be very hard to achieve.

Pure water does not exist because everybody of water interacts with animals, humans, and infrastructure. Not to mention other natural factors that make water acidic, like air and salt.

Is Reverse Osmosis Water Good (or Bad) For Your Health?

Water that has undergone reverse osmosis is very clean and safe to use. Reverse osmosis removes almost all of the impurities and microorganisms in our waters. Adding to this, reverse osmosis produces better-looking, clearer, and odorless water, leading to yet another benefit that has something to do with food.

Neutral-tasting water allows chefs to cook better-tasting food, and this is why most high-end restaurants use reverse osmosis water for their cooking.

You might be tempted to purchase a reverse osmosis water filtration system for your own home right now, but hold off on that thought just yet.

Recent studies have shown that reverse osmosis water does such an excellent job at removing small particles from our water that it might lead to health problems. 

Because we humans have never consumed pure water, our bodies have been accustomed to some of the minerals present in non-reverse osmosis water.

According to the World Health Organization, as mentioned on Atla, some of these vital minerals present in the water get filtered by the semi-permeable membrane, leaving us with something close to pure water that can be dangerous.

Since our bodies need these minerals that low mineral drinking waters do not have, our bodies have to get it somewhere, leading to the body leeching off of itself.

A study has shown that drinking low mineral drinking water might lead to several health problems in the long run, such as height retardation, bone mineral reduction, coronary heart diseases, and hypertension.

Can You Drink Reverse Osmosis Water Every day?

Although reverse osmosis is an excellent way of filtering impurities in water, it is not advised to drink it every day. 

The low mineral drinking water produced by reverse osmosis is not healthy for the body because it leads to several health problems stated above. The World Health Organization also warns people as it is not suitable for long-term human consumption. 

They also state that food diets or vitamin supplements cannot compensate for the minerals lost in reverse osmosis.

People Also Ask

Does reverse osmosis soften water?

Does reverse osmosis soften water?

No. There is a big difference between water softeners and water filters

Water softeners soften the water through the use of ionization. Water found in nature has high levels of calcium and magnesium ions. This type of water is called hard water, and a study has shown that hard water can lead to potential health risks such as cardiovascular disease, cancer, Alzheimer’s, and even diabetes.

Water softeners soften the water by replacing the harmful ions with salt or sodium ions. While reverse osmosis filters only remove all the unwanted contaminants and impurities in the water, leaving you with something close to pure water.

Is reverse osmosis water alkaline?

No, it is slightly above the acidic scale. And this can be a good thing. Slightly acidic pH water helps maintain the body’s natural acidity, especially on our insides.

Neutral or slightly acidic water will help kill bacteria and viruses that might enter our bloodstream. Too much alkalinity might lead to health problems such as nausea, vomiting, and even skin irritations.

What is better alkaline water or reverse osmosis?

Drinking alkaline water is far more beneficial than reverse osmosis water from a health standpoint. 

Reverse osmosis devoids natural water of its crucial minerals that are badly needed for the development of the body. If our bodies lack these essential minerals, it could lead to many problems.

On the other hand, alkaline water has all the essential minerals our bodies need from drinking water. Adding to this, alkaline water has also been shown to have more electrolytes, benefiting our hydration capacities.


Reverse osmosis is truly an engineering marvel made possible by our ever-advancing knowledge in science and technology. Reverse osmosis is a great way to remove all unwanted impurities in our waters; it leads to cleaner and clearer waters which can be great for cooking, cleaning, and taking baths and showers.

But as mentioned above, it’s not recommended to drink reverse osmosis water daily as it completely removes all the essential minerals present in water.
