Water Quality

Is Purified Water Bad for You?

5 min read

With water contamination issues at an all-time high, more and more Americans are turning to purified water.

But not all purified water is created equal, and research shows that some types might actually be unhealthy for regular consumption.

On the flipside, the right type of purified water can protect your family from harmful contaminants and provide nutrient-dense hydration.

Here’s what you need to know about purified water and your health:

ESSENTIAL TAKEAWAYS

Purified water is free of many different impurities, and is the norm for most public drinking water facilities.


While public water supplies are regulated and are generally deemed safe, there are some potential downsides as well.


To be safe, we recommend adding an in-home water filter. That's the only way to guarantee proper water purification.


At best, it should also be able to remineralize your tap water, such as an RO filter. That way you'll always get the minerals that your body needs!

What Is Purified Water?

Purified water is water that’s filtered and processed to remove impurities like:

  • Bacteria
  • Parasites
  • Fungi
  • Pesticides
  • Copper
  • Lead
  • Arsenic
  • Nuclear waste

In America, most public drinking water is filtered and disinfected to make it safe for consumption. Here’s how:

How Are Public Water Supplies Purified?

Compared to most countries, the process for purifying public drinking water in the US is quite thorough.

Common treatment methods include:

  • Sedimentation: Large particles are allowed to settle at the bottom of the water supply so they can be separated from the rest of the water. 
  • Flocculation: Positively charged chemicals are added to the water to attract and remove negatively charged pollutants. 
  • Filtration: Clean water from the top of the water supply travels through multiple layers of gravel, sand and charcoal to remove bacteria and chemicals.
  • Disinfection: Chemicals like chlorine are added to the water to kill any remaining bacteria and viruses.

Unfortunately, these steps aren’t always enough to prevent dangerous levels of contaminants from sneaking into your drinking water.

DID YOU KNOW?

Every year, your community water supplier has to provide an annual report, called a Consumer Confidence Report (CCR). It will tell you everything about the water quality, source, contaminants, and so on. You can check here if yours is available online!

Are There Any Downsides to Public Tap Water?

Although purified public water is generally safe enough to prevent outbreaks, it can come with several downsides…

Most treatment plants add fluoride to help prevent tooth decay, but some evidence suggests that long-term fluoride consumption can be toxic to the nervous system, especially in developing fetuses and young children. 

At the same time, chlorine and other disinfectants can accumulate in the body and increase the risk of cancer

Even worse, trace contaminants like lead and copper can wreak havoc on the gut and brain.

Benefits of In-Home Water Purification 

When it comes down to it, the only way to guarantee that your water is truly safe is with an in-home water system.

In fact, in-home systems add extra layers of filtration that public treatment centers don’t. Depending on the type of system, it can remove up to 99.9% of harmful contaminants like lead and pesticides. 

At the same time, in-home systems remove all of the undesirable chemicals added by treatment plants, like chlorine and fluoride, so that you can protect your family from their neurotoxic effects.

We need essential metals and other minerals for our body to activate enzymes. They are molecules that do very important jobs for our overall health.

Purified Water Minerals Are Healthy

Health Risks of Demineralized or Low-Mineral Water

The best home water filters also soften the water by removing excess amounts of “hard” minerals. 

This is great for the health of your pipes and appliances, but it’s not so great for your body. 

Furthermore, the importance of minerals in drinking water has been recognized by Aurvedic medicine for thousands of years, and modern medicine agrees! Minerals like calcium and magnesium boost energy, prevent muscle cramps, and support brain function. 

In fact, literally every organ in the body relies on minerals to function properly, and removing them from your drinking water can seriously hurt your health.

Side effects of drinking demineralized water can include:

  • Calcium and magnesium deficiency
  • Poor absorption of nutrients
  • Increased absorption of toxic metals
  • Negative effects on cellular metabolism 
  • Damage to the intestinal mucous membrane

Finally, drinking water that’s low in calcium and magnesium can increase the risk of bone fractures, preterm birth and heart disease.

Distilled Water vs Reverse Osmosis - What’s the Difference?

When it comes to kicking some serious toxin booty, the frontrunners are reverse osmosis and distillation. 

Boiling water and collecting the steam creates distilled water. What's left is nothing but contaminant-free water.

This process is especially effective at removing bacteria, viruses and other pathogenic microorganisms. 

Distilled water is so pure that it’s often used in medical facilities for patients with compromised immune systems. 

But there are several downsides to distillation, including:

  • Will not protect your pipes from “hard” water
  • Are less practical for producing large quantities of drinking water
  • Most systems do not include a remineralization phase

Reverse osmosis systems, on the other hand, can supply your entire family with pristine drinking water and protect your pipes year round...

What’s the Best Way to Purify Your Tap Water At Home?

High-end reverse osmosis (RO) systems combine several different stages of filtration to remove 99.9% of harmful contaminants.

In early stages, they soften the water and remove hard minerals, then in the final remineralization stage they add healthy minerals back in.

Let’s take a closer look at how RO systems work:

  • Step #1: Sediment filters remove large particles of dust, rust, dirt and debris to remove discoloration and decrease the burden on the rest of the system. 
  • Step #2: Activated carbon (charcoal) filter traps organic chemicals and disinfectants. This improves the smell and taste of your water and protects your family from the toxic effects of chlorine.
  • Step #3: Ion exchange resins remove “hard” minerals and protect your pipes and appliances from stains and calcification.
  • Step #4: RO membrane removes dangerous contaminants like lead, arsenic and nuclear waste by forcing pressurized water through a membrane with very small pores. 
  • Step #5: Polishing filter provides another layer of carbon filtration and traps any pollutants that may have snuck through.
  • Step #6: Remineralization stage adds a healthy ratio of electrolyte minerals back into the water. 

Remember, not all RO systems include this important final step. But don’t worry, there are plenty of high-end RO systems to choose from...

Should You Purify Your Family’s Water?

In the last decade, as many as 63 million Americans (that’s one-fifth of the country) were exposed to potentially unsafe drinking water. 

Rural areas where most homes are on private wells are the worst off, but municipal water supplies are also at risk. 

The 2014 Flint Water Crisis exposed over 6,000 children to high levels of lead, and similar events continue to occur across the country. 

Although the Environmental Protection Agency (EPA) regulates over 90+ contaminants, it’s ultimately up to the state and local governments to enforce them, and they often fall short. 

If you want to guarantee toxin-free drinking water, installing an RO system is usually the best option. 

Cloud Water Filters remove 99.9% of dangerous contaminants and remineralize with essential electrolytes. They also sync to an app on your phone so that you can monitor your water quality 24/7.
