Why some Water Purifiers/ Dispensers / Ionizers could cause more harm than regular tap water?
90% of rival water purifiers and dispensers are unable to remove fluoride nor pass this Heavy Metals test
One of the main reasons you should get a water system is to remove the Heavy Metals in your drinking water, which can be caused by corroded water pipings, incompetent maintenance of water storage etc. These Heavy Metals damages our DNA structure, affects cognitive functions & development, induces cancer and many other acute and/ or chronic disease, taking away the quality of our life.

HEAVY METALS ARE also part of the TDS in water.

The best way to know if your drinking water is good enough is by running electrolysis water test, recognised by the Food & Drug Administration (FDA) of the US as the simplest and most efficient water quality test for the presence of Heavy Metals. A short 30-60 seconds would do the job in letting you know what your drinking water contains.

For Coral Pure’s filtered water, we put it to the test and we’re proud to share that test shows abundance of rich natural alkaline minerals present in the water, turning yellow during the electrolysis, while other water samples turned black, indicating presence of Heavy Metals!

​Coral Pure filtered water remained yellow even after 2 rounds of Electrolysis conducted!

Our Key Advantage
How Coral Pure Removes Heavy Metals, Harmful TDS & Fluoride, and remineralises your water

TDS is easily removed through our Reverse Osmosis process. Reverse osmosis is a method for treating water and wastewater by applying pressure to the water to filter out salt ions. This process allows us to remove up to 98% of TDS through its 0.0001 micron membrane. (Also certified as highest filtration Spec due to its finest pore size)

Filtering harmful TDS can only be achieved by USA NSF ANSI 58-certified Reverse Osmosis (RO) Filtration, but only about 5% of water purifiers in the market incorporate RO system.

If you’d like to use water purifiers to remove the TDS in your drinking water in Singapore, you must know that about 90% of water purifiers in the market do not have the capability to remove TDS from tap water.

Meanwhile, Coral Pure Natural’s water purifiers remove up to 98% of TDS in the water that you consume.​

Filtering harmful TDS can only be achieved by USA NSF ANSI 58-certified Reverse Osmosis (RO) Filtration, but only about 5% of water purifiers in the market incorporate RO system. Coral Pure Premium 9 series system has that, plus remineralising Pure RO water into Premium natural alkaline hydrogen mineral water.

The following link is from Australia and USA Government official website, advisory on suitable water filter for home. (Both recommended Reverse Osmosis (RO) filtration to remove toxic impurities from water supply effectively)

Why you need to Remove Heavy Metals, Fluoride and Harmful Total Dissolved Solids

What are the most TOXIC impurities in drinking Water which more than 90% of water purifier / water dispenser cannot remove?

The answer is Fluoride & Heavy Metals.

Both of these are the most difficult to remove. The majority of Korean or Japanese water purifiers don’t fulfil the removal task. USA NSF ANSI 53 CERTIFIED filter removes only some of the Heavy Metals but is unable to remove Fluoride and TDS.

Only NSF 58 Certified Filter removes FLUORIDE AND HEAVY METALS effectively including 98% of TDS, and generate close to distill pure water.

***NSF 42 certified to remove chlorine and improve taste. It doesn’t remove heavy metals and fluoride.

Meanwhile, Coral Pure Natural’s water purifiers remove up to 99.9% of fluoride in the water that you consume. Our Premium 8++ water purifier can achieve up to 95% fluoride removal with 0.0001-micron filtration while our latest Premium 9 water purifier can achieve up to 100% fluoride removal due to our fluoride removal water filters and reverse osmosis filtration.

What is Total Dissolved Solids (TDS)?

Total Dissolved Solids (TDS) is a measure of the total concentration of dissolved solids. It is essentially a measure of harmful impurities, minerals, or anything dissolved in water that is not an H2O molecule. TDS in water can come from anywhere, including natural water springs, chemicals used to treat the water supply tanks, and even from your home plumbing system.

The common types of total dissolved solids, heavy metals and their chemical names include Aluminium, Cadmium, Arsenic, Chloride/Chlorine, Copper, Fluoride, Herbicides, Iron, Lead, Sulfate, and Mercury. In fact, there are more than 24 types of toxic heavy metals in water supply.

Here is an official quote from the World Health Organization (WHO) about the health effects of heavy metals in water:

“Heavy metals are toxic elements that can damage the brain, central nervous system, blood, kidneys, liver & other organs. They can also interfere with the immune system & the normal development of children. The health effects of heavy metals depend on the type of metal, the dose & the duration of exposure. Some heavy metals, such as lead & mercury, can accumulate in the body & cause long-term health effects, even at low levels of exposure.”

Note: There’re about 24 types of heavy metals which are high risk to human bodies

Harmful Effects of Fluoride, Coral Pure Eliminates it!

Many developed nations do not fluoridate their water. Fluoridation of tap water is banned in most developed countries such as Europe, Japan, Korea, China and Russia. In western Europe, for example, only 3% of the population consumes fluoridated water. Only 11 countries in the world have more than 50% of their population drinking fluoridated water:

Over the past two decades many communities in Canada, the USA, Australia, and New Zealand have stopped fluoridating their water supplies. In Israel, the Minister for Health announced in April 2013 the end of mandatory water fluoridation.

Fluoridation of tap water is banned in most developed countries such as Europe, Japan, Korea, China and Russia. Research also shows that fluoridation can cause slower development for children and affect their IQ or cause autism.

Fluoride which is more toxic than Chlorine is also most difficult to remove from tap water.

Yet, about 95% of water purifiers in the market cannot effectively remove fluoride as their filtration pores size is bigger than 0.0001 Micron. For fluoride and Heavy Metals removal, look out for Certified Reverse Osmosis membrane (0.0001 Micron) in compliance with USA NSF ANSI 58.

More Harmful Effects of Fluoride
Fluoridation can cause slower development for children and affect their IQ or cause autism. A 2012 study by the Harvard School of Public Health found that children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.​
Dental fluorosis occurs when you consume too much fluoride while having teeth that are still encased and growing under your gums. This is particularly common for young children who are still having their baby teeth. Children are also more likely to ingest toothpaste, which is also another concentrated source of fluoride. This may result in white spots forming on the external layer of your teeth, making your teeth look less aesthetically pleasing.
Skeletal fluorosis is similar to dental fluorosis, but it involves the damage of bones instead of teeth. Early symptoms may cause joint pain. Over a longer period, skeletal fluorosis may further damage the bone structure and the skeletal system.
Evidence shows that male rats that were given high fluoride content to drink for two years have an increased risk for bone tumours. This type of bone tumour is known as osteosarcoma. This risk was not witnessed or seen in female rats (PMC, 2018). Boys also have an increased risk than girls of developing osteosarcoma when exposed to fluoride drinking water (PMC, 2011).
From Straits Times Article: Fluoride Levels May Pose Risks to Children

Dr Wuang Shy Chyi, domain lead for water technology at Temasek Polytechnic’s School of Applied Science, said that due to their natural sources, mineral water can contain trace amounts of elements. While some elements such as arsenic, can be beneficial in tiny quantities, Dr Wuang notes: “Some minerals, like fluoride, may also be present in quantities that are not acceptable to certain groups of people.” These include infants and young children, who already get fluoride that is added to tap water.

A 2012 study by the Harvard School of Public Health found that children in high-fluoride areas had significantly lower IQ scores than those who lived in low-fluoride areas.

Does Boiling Water Remove Fluoride & Heavy Metals?

The short answer is no as fluoride and heavy metals do not evaporate or boil easily as chlorine does. This chemical element’s boiling point is much higher. Also, the volume of water decreases as it boils, increasing the concentration of fluoride, heavy metals and TDS in the water.

    All our testimonials and reviews on health improvement are of Type E (Premium 8 and 9 series)

    They fulfill the capabilities of removing all kinds of toxic impurities, especially Fluoride, Heavy Metals and bacteria which more than 95% of water purifiers cannot achieve.

    Almost 100% of our users who drink min 3 litres of our Type E system experienced health improvement or maintained their health better.

    For Type B (Premium 4, 5 and 7) and Type A, C and D, we do not recommend drinking more than 2 litres, as harmful TDS are not removed. This includes heavy metals and fluoride which is only partially removed. For Type D, it is Pure distilled or RO water without minerals, which can cause health deterioration.

    Thus, the type of water also determines the amount you should drink!

    good drinking water

    We wish to emphasize that Singapore PUB tap water is well regulated. The heavy metals and fluoride contents are within WHO Guidelines. Although many developed countries banned fluoride, Singapore is one of the few countries that fluoridate tap water, still within the safe limit for consumption. (Only around 5% people worldwide drink artificially fluoridated water)

    Frequently Asked Questions

    Reverse osmosis is regarded as one of the most effective ways of removing water contaminants to create pure and healthy drinking water. Installing a reverse osmosis system for your home is worth the investment as it can remove 99% of asbestos, lead, and other contaminants from water, providing your household with mineral-rich alkaline drinking water.

    Having clean and healthy drinking water is important in every household. A reverse osmosis purifier can help filter even the most elusive water contaminants out there. The cost of installing a RO water purifier in your home varies and will depend on your specifications and requirements. For more information on pricing and installation costs, you can send us a message. We will answer your enquiries as soon as possible.

    There are a few RO water purifier brands available in Singapore. However, Coral Pure Natural is the only company in the country that is NSF-certified. Our water filtration and purification systems have the highest filtration specifications that can provide healthy, clean, and mineral-rich water.

    Tap water contains contaminants; therefore, purification is necessary, and it is not possible to obtain pure water without RO filtration. However, it is not ideal to drink water without minerals. Look for a filtration system that includes both RO and remineralizing filters. Coral Pure comes with 3 to 6 remineralizing and restructuring filters that have crystal-energizing hydrogen after the RO filtration.

    Due to the harmful health impacts that fluoride can have, many adults and children have switched to using fluoride-free toothpaste. The latest medical research has shown that fluoride may cause more harm than good to human body and teeth.

    Drinking pure RO water is not ideal.

    RO water is acidic and can be harmful to our bodies. However, without RO filtration, it is impossible to obtain clean and pure water. RO filtration has the finest membrane pore sizes of 0.0001 micron, making it the only filtration type capable of removing fluoride, heavy metals, and other toxic impurities.

    Coral Pure includes 3 to 6 remineralizing filters after the RO filtration process. These filters generate antioxidant crystal-energized alkaline hydrogen mineral water that has been proven to benefit the health of users of all ages, from toddlers to the elderly.

    Natural Alkaline Minerals such as calcium and magnesium are essential for our bodies to stay healthy. These minerals are necessary nutrients that support the proper functioning of our bones, teeth, and blood. However, our bodies cannot produce them internally, so they must be obtained from external sources, such as food and water.

    Antioxidant Hydrogen Water has smaller cluster size molecules, it allows the natural alkaline minerals to be absorbed by our bodies faster than minerals. That’s why drinking alkaline water is the best way to supplement our bodies’ mineral deficiencies and enjoy the multitude of benefits they provide.
