Is Coway Reverse Osmosis Water safe to drink?

Are you looking to buy a water filter for yourself and your family?

If so, you have probably done some research online and know some basic information about Reverse Osmosis (RO) water filtration technology. You probably still have a lot of questions too.

While opinions differ greatly on the benefits of different water filtration methods, reverse osmosis seems to often get targeted unfairly by articles written and posted online. Why is there such negativity towards reverse osmosis water treatment and can we trust these articles to be accurate? Are they telling the truth or just spreading misconceptions and lies?

In this lens, I will discuss both the positives and negatives of RO systems to help you sort through all the myths, half-truths, and falsehoods associated with the technology.

Myth #1 - Reverse Osmosis Water is Unhealthy to Drink

Truth: Reverse Osmosis water is very clean and good for our bodies.
Reverse osmosis has been called dead water because of its purity. Detractors say it is man-made, unnatural and unhealthy. They claim that RO water can only be used for industrial applications and not for human consumption. They say that RO water is too pure and clean to be good because such perfectly clean mineral-free water does not exist naturally on earth. They forgot about a little thing called RAIN.

Rainwater is water that has been stripped of all minerals and is one of the purest and cleanest water on earth. Human beings have relied on drinking rainwater for thousands of years without any negative health effects. Only recently has rainwater been polluted by the industrial age and man's pollution of the skies. Ask yourself this. What can be more natural than mother-nature's life giving rain?

With all the scientific research that has been done over the years on reverse osmosis water, none has ever documented any negative health effects from water treated by this method. In fact RO technology was actually invented by the US military and our military personnel still use it currently for drinking water.

Some more facts to consider.

1. Bottled Water = RO Water
When you drink many
 brands of bottled water, you are actually drinking RO treated tap water.

2. Soft Drinks = RO Water
When you drink soft-drinks and soda, you are drinking mineral-free treated RO water. Vitamin water, sports drinks & energy drinks are also made from RO purified water.

3. Tap Water = RO Water
Some US city and municipal water facilities (Orange County, CA) are already providing RO treated water to their communities. Los Angeles county is also
 considering RO systems as we speak. Even Beverly Hills 90210 is using RO water. Hey if reverse osmosis is good enough for the OC and the Hollywood elite that must tell you something!

4. GE & DOW water = RO Water
General Electric and DOW chemical are two of the largest and most respected companies in the scientific community and both sell and
 endorse reverse osmosis technology for drinking water.

5. Arrowhead & Culligan water = RO Water
Arrowhead, Culligan, Aquafina and Dasani are just a few brands that sell reverse osmosis water.

6. Google Campus Water = RO Water
Google employees have on-site doctors, massage therapists, nutritionists, yoga classes and volleyball courts at their finger tips. They also have delicious
 reverse osmosis drinking water too.

The truth is many of us have been drinking reverse osmosis water all our lives without even kno
wing it.

Myth #2 - Reverse Osmosis Removes Healthy Minerals from Water

Truth: Reverse Osmosis removes inorganic minerals which are UNHEALTHY.
RO systems do remove minerals from tap water. However, we humans get the vast majority of our minerals from the foods we eat, not from drinking water. For example, 1 glass of orange juice has the same amount of minerals as 30 gallons of tap water. Try drinking that for your morning breakfast!

Another thing they don't mention is the type of minerals found in water. Tap water contains only inorganic minerals which cannot be properly absorbed by our bodies. Human beings need organic minerals which are only available from living organisms like plants and vegetables and are easily absorbed by our systems. The inorganic minerals found in water has little to no benefits to people and in fact are actually detrimental to our health.

It is estimated that over a 60-year lifespan, a person drinking tap or mineral water will be ingesting about 200 to 300 pounds of rock that their body cannot use.
 (These are the so-called "healthy minerals" that RO detractors complain are being taken out of the water!) While most of these minerals will be eliminated, some will be stored in our tissues becoming toxic. The primary culprits are calcium salts and over time they can causegallstones, kidney stones, bone & joint calcification, arthritis, and hardening and blocking our arteries.

"What the human body cannot utilize or excrete, it must store. Consequently, the inorganic salts (inorganic minerals) are stored and in time take their toll in the form of hardening of the arteries, stones within the kidneys, urethras, gall bladder, joints and an etiologic factor in enlargement of the adipose cell (fat cell). To be one hundred percent healthy, the human body must be free of inorganic minerals."

World Renowned Nutritionist, Pioneer in America's Wellness movement
Paul promoted and drank mineral-free water all his life and died at age 81 from complications after a surfing accident!

Revere osmosis water purification simply delivers the cleanest, purest drinking water on the market. In fact, reverse osmosis is the only purification system that can remove dangerousPharmaceuticals & Drugs
 from our drinking water. According to AP news reports provided by this USA Today article & Fox News report - "Reverse Osmosis removes virtually all pharmaceutical contaminants".

According to the WQA & WHO(Water Quality Association - World Health Organization) we get the
vast majority of our minerals from food not from drinking water.
Water Quality Association (WQA) Technical Services Consultant Regu Regunathan, PhD, and WQA Technical Director Joseph F. Harrison, PE, CWS-VI, both spoke at the April symposium. Harrison said he agrees with the WHO report's major conclusions:

1. Both calcium and magnesium are essential to human health.

2. Food is the principal source of both calcium and magnesium.

3. Suppliers of water - including municipal, purified bottle water, and POU/POE treatment water providers - may make information on the mineral content of their water available to the consumer.

The lack of minerals in your water should not keep you up at night. The increasing amounts of chemicals and drugs found in tap water should!

Myth #3 - Reverse Osmosis Produces Very Acidic Water with Low pH

Truth: Reverse Osmosis produces mildy acidic or neutral water
Reverse Osmosis may reduce pH levels somewhat as it removes unhealthy inorganic minerals from tap water. However the reduction is not certain and would be very small and not detrimental to human health. The truth is, water pH will automatically change when it is ingested and comes into contact with the food in your stomach. Even on an empty stomach, your stomach acid alone is already several times more acidic than RO water with a pH level of 2.

The human body regulates pH levels constantly to find balance and equilibrium. Therefore under normal conditions it will always maintain a neutral 7.4 pH balance. Even eating very acidic foods (very low pH) only alters the body's pH by a very tiny amount and only for a short time. The healthy body is very robust and it will restore homeostatic pH fairly quickly and easily.
As long as you eat a well balanced diet which includes vegetables and fruits, you can pretty much drink whatever you want without ever worrying about your pH balance.

Water pH Levels (May Fluctuate)
Sea Water = 8.6 pH (alkaline)
Mineral Water = 7.4 pH (mildly alkaline)
Tap Water = 6-8 pH (Varies constantly)
RO water = 5-7 pH (Depends on pH of input water)

Beverages pH Levels
Sodas and Cola Drinks = 2.5 pH
Sports Performance Drinks = 2.9 pH
Orange Juice = 3 pH
Coffee = 4 pH
Beer = 4.5 pH
Milk = 6 pH

Healthy Human Body pH levels
Blood = 7.4 pH
Stomach = 2 pH
Mouth = 6.7 pH

Myth #4 - Water Experts Disapprove of Reverse Osmosis Systems

Truth: Water Experts = Affiliate Salespeople!

Do not trust the majority of articles posted online by so-called "Water Experts" that attack RO water filtration as unhealthy. About 90% of them were written by the sales affiliates of a single countertop filter company which competes directly against RO sellers.

How do I know this? Well 90% of these articles all link back to websites that sell and promote only one brand of countertop filter. Their articles are posted all over the internet with the sole purpose of pushing people into buying their filters. They never back up their claims with sources or links because the primary purpose of these articles is to make money for the affiliate.

As stated above, the water scientific community believes that RO water is healthy to drink. So who are you going to trust? The EPA & WQA, or a bunch of affiliate salesmen on the internet?
