IS Drinking RO Water Safe?

Reverse Osmosis, or RO for short, is a popular water filtration method used in many homes for drinking water. It takes out the largest spectrum of contaminants when compared to any other water filtration method. Well, technically deionized water systems take out more, but DI water is not something you would want in your home for drinking water. RO water is like having bottled water comes directly out of your faucet. Recently some people are voicing a growing concern about using reverse osmosis water - this is because they have been told that reverse osmosis removes all of the beneficial minerals. So, is RO water safe and healthy to drink, or are the risks not worth the reward? Let's discuss.


Again, a RO system takes more contaminants than regular filtration. Bacteria, lead, chlorine, sodium, fluoride, pharmaceuticals, arsenic, and a whole list of other contaminants.  But, one downside is that while all those unwanted contaminants are being removed, the reverse osmosis membrane also removes 90 percent of the minerals in the water. Now first off let’s be clear – water is not a sufficient source for your daily minerals. If you drank a bathtub of water a day, you might not get 10% of the minerals your body needs. Water is just not a major source of your body's minerals. However, there are lots of things about drinking water that should concern you. Things like lead, chromium 6, arsenic, chloramine, and about 35,000 other chemicals. Now, on the flip side, the World Health Organization released a study that the 90 plus percent of minerals that Reverse Osmosis removes can have long-term health risks. While the science is still out, they warn that the lack of minerals in the water can negatively affect the minerals your body gets from your diet and even supplements. Here is a quote from their study: "reduced mineral intake from the water was not compensated by their diets...low-mineral water was responsible for an increased elimination of minerals from the body."  Pretty much what they are saying is lack of minerals like calcium in the water may cause your body to leech away any others that it consumes, meaning your body may not get all of the beneficial minerals that it needs.


So what do you do? Should you avoid a RO system and risk drinking unwanted contaminants to make sure that your body gets enough minerals? Places like Flint, Michigan have proven that to be a risky gamble. I encourage everyone to do their own research to decide if a reverse osmosis system is right for them, but if the lack of minerals is a concern for you then there is a way to have the best of both worlds. Remineralization filters can be added to reverse osmosis systems, these filters attempt to add the mineral content back into the water. It’s clean crisp RO water but with all the minerals. Unfortunately, most remineralization filters on the market that are placed after an RO are highly ineffective. Tests have been done that show while the pH has been raised after the RO water runs through the filter, very few minerals have effectively been added.

Our Solution

We at US Water Systems, believe that RO systems are the safest choice for drinking water in your home becomes of the harmful contaminants that it removes, but if you are worried about the lack of minerals, we offer our All American Reverse Osmosis System with a Livation filter as an add on option. This made in the USA filter not only adds minerals back into the water but also raises the pH and increases hydration absorption by lowing the water's ORP (oxidation-reduction potential). So in closing, if you want the benefits of RO water but still want the minerals – know that there is a technology out there that can give you both. Thanks for reading.
