A Look at the Benefits and Downside of RO Bottled Water

Bottled Water as a Source of Contaminant-Free Water

Because of the ever-increasing levels of pollution, quite a number of our natural water sources are getting contaminated with dangerous chemicals at an alarming speed. This raises the question of the safety of drinking water that isn’t treated thoroughly to remove such contaminants.

Realizing this, an increasing number of concerned people have been working on improving the quality of purified drinking water available to us. Bottled water as a source of clean, uncontaminated water seems to be gaining popularity nowadays.

In fact, according to the International Bottled Water Association (IBWA), the U.S. bottled water consumption in 2015 is a whopping 11.7 billion gallons. This is a testament of how more and more people are drinking bottled water now more than ever.

We can attribute this increasing demand to the fact that bottled water is indeed one of the “cleanest” sources of drinking water. Thanks to the technique called Reverse Osmosis or RO that many bottled water brands employ to purify water.

This technique might be familiar to you as it’s heavily advertised as the best method to clean water. If you ever want to dig deeper on what exactly this technique is and how it’s done, you are in the right place.

Reverse Osmosis Explained

Basically, reverse osmosis is a filtration process with a more efficient principle compared to the regular filtration process—filtration happens at a molecular level. Thus, it can get rid of almost all the dissolved contaminants present in tap water.

The RO process uses a component called “semipermeable membrane.” This is a filtration mesh that can selectively allow the passage and capture of different molecules in tap water based on their sizes.

Despite being invisible to the naked eye, dissolved chemicals have different molecular sizes than water. Most of these dissolved contaminants are larger than water molecules.

When contaminated tap water passes through the semipermeable membrane in the RO process, contaminants whose molecules are larger than H2O are filtered successfully.

Most purification processes (like that of distilled water) do not employ molecular filtration. While they may remove most of the undissolved contaminants, they can’t do much to get rid of the dissolved impurities.

In contrast, reverse osmosis can filter as much as 99% of all dissolved contaminants in tap water. The RO process produces a pure quality of water making it the preferred filtration process of many companies in the bottled water industry.

Benefits of Reverse Osmosis

  • The biggest advantage of RO water is the rate of purity.
  • Reverse osmosis can filter out lead, pesticides, heavy metals, and other organic components.

Downsides of Reverse Osmosis Water

While reverse osmosis water might be pure, there’s more to it than meets the eye:

  • Reverse osmosis water is devoid of essential minerals.
  • Reverse osmosis water can leach minerals from your bones over time.

Since this process filters 99% of all dissolved chemicals from water, it also removes beneficial minerals.

We get a percentage of our calcium and magnesium requirement from drinking water. In its purity, reverse osmosis water is devoid of minerals including these two.

This might not look like a big deal but prolonged consumption of reverse osmosis water can affect one’s health negatively.

A 2002 World Health Organization study in the Czech Republic found that people who exclusively drank reverse osmosis water developed lower levels of calcium and magnesium. This translates to higher risks of heart and other complications.

  • RO water flushes out other stored minerals in the body.

Additionally, since water contains no dissolved solids, it leaches away stored minerals too as it runs through the body. These minerals are eventually excreted through urination.

The lack of calcium and magnesium intake and the increased erosion of the stored reserves in the body lead to a deficiency.

  • Filtered RO water leaves out waste material.

The process of reverse osmosis itself is not exactly self-sustaining. The membrane used to filter out chemicals and bacteria, for the most part, gets clogged with salt, chlorine, and unsafe microorganism residues.

So even if you end up having clean drinking water, you leave the environment — especially marine life — with toxic waste when you rely on reverse osmosis to filter your home water.

  • RO water takes longer to produce.

Other home filtration systems perform their purpose faster than reverse osmosis set-ups.

RO systems usually take 3 to 4 hours to produce 3 liters of clean drinking water. This means that it may take a day to produce enough water for the whole family.

  • Reverse osmosis water is actually acidic.

As minerals that make it alkaline are removed in RO water, its pH drops. Drinking it, then, poses risks to the body.

If the extracellular fluid (where our cells are exposed to) becomes too acidic, the body’s defense mechanism weakens. The consequences manifest as biological symptoms like stomach pain and headache.

Drink reverse osmosis at your own risk. The said downside might be prevented by increasing mineral intake through diet or consumption of supplements.

Or, better yet, install a water ionizer for your home or buy a portable water alkalizer for when you’re out and about.
We’ve laid out the considerations—it’s pure but this same benefit is also the cause of its disadvantage.

Drinking reverse osmosis bottled water with its purity is generally safe but there is a caveat. It calls for the uptake of minerals from other food sources or supplements to prevent the development of deficiencies.
